Sustainability in Cannabis Packaging: Balancing Preservation and Environmental Impact

By Jack Grover
No Comments

Even a cursory review of cannabis reveals that the market has been notoriously wasteful, polluting the environment with chemical fertilizers, misused pesticides, contaminated plants, and—perhaps most problematically—thoughtlessly excessive packaging.

The industry is in dire need of sustainable practices, and the easiest way to start an impactful new trend is from the outside in: a.k.a., adjusting how you’re parceling your products.

Honing in on sustainable packaging isn’t just a good move for the environment. It’s also more cost-effective, less labor-intensive and allows you to provide consumers with the best possible version of your flower—no matter how far through the supply chain it’s had to travel before hitting retail shelves.

Cannabis has progressed: It’s time for its packaging to do the same

By the time legalization began sweeping the nation, the industry already had several decades of experience operating underground. With that discretion came a lot of built-in habits around not attracting attention, and for packaging, the focus was solely on not looking like a cannabis product.

An overabundance of plastic isn’t cutting it anymore—not only when it comes to environmental friendliness, but for the integrity of the product itself.

Today, increased legalization grants operators the freedom to expand without the fear of being seen, and as a result, there’s no longer any excuse for wasteful packaging to be the industry’s norm. Glass jars, Ziplocks and an overabundance of plastic isn’t cutting it anymore—not only when it comes to environmental friendliness, but for the integrity of the product itself.

“I’ve been designing packaging in the cannabis industry since 2013, and a lot of trends have come and gone. We used to put flower in plastic Rx jars and paper envelopes. In general, there was a lot of waste: excess boxes and jars that all get thrown away,” says Legacy’s Chief Cannabis Officer Ryan Hedrick. “And when consumers pull the products out of those containers, your marketing doesn’t remain intact. The box gets thrown away, and now they’re just carrying around a labelless jar. Not only is it bad for the environment, but it isn’t helping you promote your brand at all.”

How sustainable storage optimizes curing and shelf life of flower

As for the curing process, Hedrick used to use airtight buckets, which both took up a lot of room and wasn’t at all effective for maintaining cannabis’s ideal humidity levels. He’s since switched to passive atmospheric packaging, which utilizes increasingly popular technology to keep humidity—and sustainability—in mind. “The buckets weren’t letting any moisture out. On top of that, you can imagine how much room 165 five-gallon buckets takes up in a grow space,” Hedrick says.

The same goes for long-term storage. With humidity-controlled bags, operators can rest assured that their product will maintain its efficacy, because as soon as that pack is sealed, the humidity level is guaranteed to stay the same.

Cannabis brand Lava Leaf Organics relies on passive atmospheric packaging for efficient storage—mainly because of the reduction in carbon footprint and increase in terpene preservation.

“When we think about the energy involved in packaging and shipping large amounts of heavy glass jars compared to TerpLoc bags, it was an easy decision for us,” said Lava Leaf Organics CEO Tony Martinez.

“The bags are recyclable, and compared to glass jars with child-resistant lids, they’re much better at preserving terpenes. Using sustainable packaging allows us to put our best foot forward and to better control our customer’s brand experience.”

Tips for making sustainable storage work for you

Sustainable storage is an environmentally-responsible move for the cannabis industry to make, but when weighing the pros and cons of a big switch like this, operators should also keep in mind how positively it will impact their end product, consumer’s experience, and, subsequently, their industry-wide reputation.

Some product packaging examples in the market today

Placing your products in eco-friendly bags is just the start. There are definitely more tips and tricks operators can take advantage of to prolong the use of sustainable materials and ensure they’re leaving as small a footprint as possible. For example, Hedrick’s team reuses their passive atmospheric packaging for maximum efficiency—especially when it comes to bulk storage or curing.

“We mark all of our storage bags with the original strain, so we can reuse that bag for the same strain as long as it passes testing along the way. When I do so, I take a mixture of SaniDate and water to make sure everything is sanitized and clean,” Hedrick said. “That allows me to reuse them for about 3-4 months’ worth of curing and storage. You can reuse a bucket in that same way, but when it’s time to replace it, you’re still spending another $15-$17.”

Sustainable, humidity-controlled packaging is also ideal for testing consistency. If you send in five buckets of the same strain to be tested, you run the risk of them all sitting at wildly different humidity levels, which means some might pass, and others might be rendered trash.

All of the environmental benefits aside, using sustainable packaging just makes cents—literally. “Essentially, I’m saving a minimum of half a million in packaging every year. That’s my entire staff’s salary for two months. That’s incredible, impactful, significant savings that can make a huge difference for a business trying to expand.”

How the Supply Chain Crisis Impacts Cannabis

Since early 2020, the pandemic has shined a spotlight on the global supply chain and its shortcomings. Supply and demand have changed so much and so quickly that it has fostered shortages and delays for many of the world’s goods.

Much of this crisis is due to manufacturing plants in countries like China working at half-capacity or being forced to shut down to curtail the pandemic. A lot of those shortages can also be blamed on companies with a lack of foresight, choosing to lower costs with thin inventories rather than keeping warehouses full.

The global supply chain crisis has impacted nearly every market on earth that relies on international shipping. Everything from clothing and turkeys to cars and computer chips is in short supply, causing prices and wait times to increase.

John Hartsell, CEO & co-founder of DIZPOT

The cannabis industry is no exception; the supply chain crisis very much so impacts cannabis products getting to consumers. According to John Hartsell, CEO & co-founder of DIZPOT, a cannabis packaging distributor, the worst, when it comes to the supply chain affecting the cannabis market, may still be on its way. “Supply chain issues will continue to be challenging and may even become more challenging for cannabis companies over the next several months due to the holiday season coming up with many packages coming for Christmas, Hanukkah and other holidays,” says Hartsell. Many of those gifts arriving during the holidays are coming from overseas, which further exacerbates any current supply chain backlogs.

John Hartsell will be speaking on this topic and more at the Cannabis Packaging Virtual Conference on December 1. Click here to learn more.Adding to those issues even more is the Chinese New Year coming on February 1, 2022. “The Chinese New Year can often be a three-week downtime for manufacturing in China, causing even more significant delays,” says Hartsell. “Ultimately, these issues are only a problem for organizations that are incapable of planning a logistical timeline that meets demand.”

So how can cannabis companies get ahead of supply chain planning? Hartsell says they are working with customers to establish timelines up to eighteen months out to prevent any disruptions. “We need to stay hyper-focused on logistics, moving freight all over the world, to prevent issues that result from shortsightedness.”

The supply chain crisis impacts nearly every market on earth that relies on international shipping, and cannabis is no exception.

With new markets coming online and legacy cannabis markets expanding, the cannabis supply chain is certainly maturing and this crisis may be kicking things into high gear. In states on the West Coast, distribution channels have expanded, rules have allowed for curbside pickup and delivery and a lot more ancillary businesses are supporting a thriving market.

Still though, the cannabis supply chain falls short in other areas, namely interstate commerce, with the federal government to blame for that. Hartsell expects to see some more interstate commerce in the coming years, and with that comes a much more sophisticated supply chain. He says using logistics software to manage supplies will be the key to continued success.

“Keep the Buds Fresh” – Packaging & Paraphernalia Laws

By Justin T. Starling, Michael C. Tackeff

Cannabis law in the U.S. is currently incoherent. What is illegal under the federal laws on the books bears little relation to what is actually happening in cities, states and counties where cannabis is legal for medical and adult use. Although legislators, lawyers and business interests are focused primarily on whether it is legal to buy, sell or grow the cannabis flower itself, the industry’s emergence is also affecting another manufacturing stalwart: packaging. If you can grow it, you can transport it. And if you can transport it, you need a container to sell it in.

As cannabis growers and retailers begin to recognize that attractive, compelling and moisture-retentive packaging can help market and sell their products to a wider audience, packaging companies are presented with an opportunity to expand into this Wild West industry. Seth Rogen is living proof that there is money to be made here: his cannabis company, Houseplant, trades on antique vibes, limited edition releases, celebrity artist sponsorships and old-school tobacco-adjacent products, splashing its unique and charismatic packaging across its website homepage.

But what do packaging industry executives need to know before venturing into the cannabis industry? Although manufacturing packaging that could be used to contain or transport cannabis products is not entirely risk-free, U.S. courts have generally refused in the past to hold manufacturers liable for making products that can be used later as drug paraphernalia. For packaging executives, two questions are of utmost importance. First, could I be held liable for producing drug paraphernalia? And second, what packaging standards must my company follow? This article will address these questions.

Criminal Status of Cannabis Under Federal & State Law 

All cannabis containing more than 0.3% THC remains illegal under federal law and under the laws of many large states, including Texas, Georgia, Tennessee and Iowa. But that’s not the full story. While facilitating cannabis production or trafficking is illegal, the federal government has enforcement priorities and restrictions on its resources. And many state and federal law enforcement officials have little incentive to pursue industries supplying trucks, packaging or lighting to a cannabis retailer in another state, as such products and services are not illegal and can be used for other industrial purposes. No law enforcement official is going to sue Staples for selling paperclips to a cannabis retailer.

Cannabis is still a “Schedule I” substance under the federal Controlled Substances Act, which is defined as substance having a high potential for abuse, no currently accepted medical use in treatment, and no accepted safe use.1 Cannabis was always a poor fit for this definition, given its efficacy in helping oncology patients cope with symptoms like nausea, but its continued classification as a Schedule I substance means that cannabis remains illegal under federal law. Despite this federal illegality, the federal government has little power—legally, practically and politically—to prosecute those engaged in the cannabis industry through activities that are legal under state law.

First, since 2014, Congress has banned the Department of Justice (DOJ) from spending a dime enforcing the federal cannabis law against individuals complying with state medical cannabis law via an appropriations rider.2 Courts have interpreted this language to mean that the DOJ may not prosecute individuals complying with state medical cannabis law,3 although there are still instances where individuals are convicted of violating the federal ban because they were found to have been out of compliance with state law.4 Though the rider only pertains to medical cannabis laws, the federal government has historically treated adult use cannabis regimes by states in a similar way.

Second, from a practical standpoint, no federal agency has the manpower to pursue even a tiny fraction of medical and adult cannabis users who are in compliance with state law, much less the industries providing support, logistics and inventory management. Though the federal ban is still on the books, no one has the power or the money to enforce it. The federal ban is thus becoming a dead letter.

Drug Paraphernalia Laws

Drug paraphernalia laws were written to provide law enforcement with other offenses to charge drug users and producers in addition to simple possession. The idea was to criminalize every aspect of the process of consuming and producing cannabis. While drug paraphernalia laws are written incredibly broadly, courts have been reluctant to apply them to companies producing packaging products.

Most packaging companies would have a defense to a suit alleging they are producing paraphernalia

Federal law explicitly defines drug paraphernalia as “any equipment, product, or material of any kind which is primarily intended or designed for use in manufacturing, compounding, converting, concealing, producing, processing, preparing, injecting, ingesting, inhaling, or otherwise introducing into the human body a controlled substance, possession of which is unlawful under this subchapter.”5 There are 15 categories of items listed as “per se” paraphernalia, including roach clips, electric pipes, and bongs.6 Packaging products do not fit any of the “per se” categories. The statute also specifies that, in determining whether an item constitutes drug paraphernalia, the court must consider “whether the owner, or anyone in control of the item, is a legitimate supplier of like or related items to the community, such as a licensed distributor or dealer of tobacco products[,]” among other factors.7

In addition, federal courts have been reluctant to apply the drug paraphernalia laws to packaging products.8 In addressing the predecessor statute to the current federal paraphernalia law,9 the Second Circuit ordered an indictment dismissed against a producer of glass vials commonly used for crack cocaine: “Since congress in enacting the Paraphernalia Act deliberately omitted ‘packaging’, ‘containing’, and ‘cocaine vials’ from its definition of drug paraphernalia, we conclude that the plastic containers produced by Lin were not ‘drug paraphernalia’ as defined by the act.”10 The law is not uniform, but even if a zealous federal prosecutor wants to crusade against a cannabis supplier, he must contend with the appropriations rider and this adverse case law.

Nevertheless, the federal Controlled Substances Act does allow property used to manufacture narcotics to be seized.11 It is possible that if a company created packaging for cannabis products, and the customer then used that packaging to pack cannabis, the inventory and packaging could be seized by federal law enforcement. But the same obstacles to enforcement discussed above would apply.

Every state has different paraphernalia laws, but most packaging companies would likely have defenses to a suit alleging they are producing or possessing paraphernalia, including lack of intent to use the paraphernalia for illicit purposes and applying federal caselaw as a defense.

Packaging Laws

State law is the primary vehicle for regulatory guidance on cannabis packaging. Any packaging company selling to cannabis retailers will need to consider both state law and federal packaging standards, which are often incorporated by reference into state law.

Federal Packaging Law

Producing a product that complies with all state standards at once might be a challenge, but adhering to individual state rules is doable.

The Poison Prevention Packaging Act is the primary source of child-resistant packaging law.12 This law does not currently apply at all to any sales of cannabis because cannabis is illegal in the eyes of federal law. There is no private right of action under this statute.13 That means that a packaging company cannot be sued by a private individual for violating the statute. At some point, if Congress chooses to loosen restrictions on cannabis, this would be a very easy statute to simply make applicable to sales of cannabis. The law already has a specific provision for liquid nicotine containers.14 But currently, this statute does not apply to cannabis at all.

State Packaging Laws

State laws are a different matter – each state that allows sales of medical or adult use cannabis has enacted different requirements for cannabis packaging. A comprehensive survey of state cannabis packaging law is beyond the scope of this article, but some state cannabis regulatory regimes explicitly incorporate provisions of the federal Poison Prevention Packaging Act.15 California has a similar requirement, as does Washington state.16 Producing a product that complies with all state standards at once (i.e., a “national” standard) might be a challenge. Contracts with buyers could include a representation that the packaging complies only with the laws of state X or Y.

Products Liability Issues

A detailed assessment of products liability is beyond the scope of this article. But in short, as this industry matures, packaging companies undoubtedly will be subject to the usual kinds of products liability issues for cannabis packaging. In other words, in a cannabis-tolerant state, a packaging company could theoretically be sued under a products liability theory if the cannabis is somehow spoiled by a manufacturing defect in the packaging or if the packaging product permits mold to grow and eventually be consumed by a user. Cannabis contract litigation is a complex subject given its unique legal status. One strategy to avoid these issues is to include a very specific dispute resolution procedure (e.g., mediation, arbitration or the like) in any contracts with cannabis companies in the U.S. It is also important to include a waiver of any defenses of the contract being against public policy due to the uncertain legal status of cannabis.

No transaction in the cannabis industry is entirely risk-free, and packaging executives should consult with local counsel in the states in which the packaging is manufactured and in the states in which they intend to sell products to ensure compliance with the law. But this industry is rapidly growing, and opportunity awaits for the packaging companies that are willing to work through the incoherence in the current laws.

Custom Designed Packaging: Is it Right for Your Cannabis Product?

By Danielle Antos

There are numerous plastic bottle and closure manufacturers in the cannabis industry today. And, there is a significant quantity of common bottle and closure styles as well. Many companies manufacture the same or similar products as their competition. But what if you’re searching for something different? Something unique that no one else has? A plastic bottle that will make your cannabis product stand out from your competition. Where can you find that package that is truly “something special?” Something that will elevate your brand?

It doesn’t matter if your cannabis business is a start-up in its infancy or a mature company with an established loyal customer following, creating attention-grabbing packaging is essential to your success. The packaging is the all-important and critical first impression. While the primary function of any packaging is to contain, protect and market your cannabis products, your packaging is a reflection of your company in the eyes of the consumer. In many ways, the package is the product. Using creative plastic packaging is a great way to differentiate your cannabis products from those of your competitors.

Finding the right manufacturing partner is the first step. Look for a company that has custom design capabilities and understands your vision for the perfect cannabis packaging.

When is Custom Bottle Design the Right Choice?

Sometimes, an off-the-shelf stock bottle and closure will work just fine. But if you are introducing a brand-new product that is unique to the industry, or if you are using a new product to introduce the fresh new look of your brand, it makes sense to develop plastic packaging that is distinct and eye-catching. You want your brand and products to look special and stand out on the shelf. There could also be filling equipment, regulatory, labelling, light sensitivity or other packaging requirements you must address as well.

Start every custom cannabis bottle project with a trusted manufacturer who thoroughly understands how you want the plastic packaging to look and the specifications it must meet. Ensuring that these qualitative and quantitative details are discussed will lead to on-time, on-budget and on-target custom cannabis packaging solution.

Achieving the Look You Want

Depending on your requirements, there could be several solutions to achieving the special look and specifications of your custom packaging. Discuss all of the design options that meet the needs of your product with your manufacturing partner; they should help you decide on the best direction for your packaging.

Selecting the right materials for your custom plastic bottle and closure is a big part of the process. Select materials that will provide the necessary aesthetics, chemical resistance, light transmission, bottle capacity and weight requirement that will protect your product.

Your manufacturer should also be able to guide you through the production process: should the bottle be blow molded or injection molded? Should it be made on IBM (Injection Blow Molding) equipment or EBM (Extruded Blow Molding) equipment? Answering these questions will ensure that the plastic bottle will be made efficiently and to the correct specifications.

Flawless Closure Integration for Your Cannabis Packaging

Designing the bottle is important, but you must also consider what type of closure will work best. Both items must be engineered to work seamlessly with each other. If the closure doesn’t work properly with the bottle, it can compromise the product it contains. Closures must always seal perfectly to ensure the integrity of the product inside. They must also be designed to function efficiently and meet the requirements of your filling operation.

A detailed CAD drawing should be provided, outlining every critical dimension of your HDPE or PET bottle and plastic closure. The CAD drawing provides the direction needed to create the manufacturing mold for your custom design. It also serves as a reference check to ensure that the product is produced according to your specs.

Ensure Quality through the Manufacturing Process

Ensure that your packaging partner has quality checks in place throughout the manufacturing process. Error detection systems, random sampling and testing will safeguard 100% conformity. It’s also important that manufacturers adhere to cGMP best practices and certifications under a globally recognized accredited program. This represents their commitment to continuously improving manufacturing processes and quality systems. It also helps minimize waste and manufacturing errors while increasing productivity. Risk of product contamination and other errors will be alleviated, and product efficacy and shelf life expectancy will be met.

Responsive Customer Service and Support

Many packaging manufacturers claim to provide exceptional customer service, but few actually rise up to that level. This is an important aspect of your project and you need to know that your questions will be answered and that your producer will keep you informed of any changes. Knowing that you can trust your supplier allows you to concentrate on other aspects of your business, like growth and profitability.

Reinforce Your Brand with Customized Packaging

In today’s competitive cannabis market, it’s more important than ever to have your product stand out from the competition. Your brand should help build awareness and develop consumer loyalty. When you deliver a consistently reinforced message, consumers will instantly recognize your brand. This consistency is a key factor in encouraging consumers to purchase your product over the competition — even when they want to try something new. Consistency makes your brand feel more dependable and people gravitate towards things they trust.

Your brand consists of more than just your logo and company name. Your brand identifies who you are, what your company stands for and the integrity of your product. Customized cannabis packaging will reinforce your brand and attract consumers to your products. Take time to find the right cannabis packaging partner who can help differentiate your brand and products from your competitors with special, eye-catching plastic packaging.

Moisture Matters: Why Humidity Can Make or Break a Cannabis Cultivator’s Bottom Line

By Sean Knutsen
1 Comment
dry cannabis plants

Vintners have known for centuries that every step in the winemaking process—from cultivation and harvest techniques to fermentation, aging and bottling—has immense impact on the quality and value of the final product.

And that same level of scrutiny is now being applied to cannabis production.

As someone who has worked in the consumer-packaged goods (CPG) space for decades, I’ve been interested in finding out how post-harvest storage and packaging affect the quality and value of cannabis flower. After digging into the issue some more, storage conditions and humidity levels have indeed come into focus as major factors, beyond just the challenges of preventing mold.

Weighty Matters

I enlisted my research team at Boveda, which has studied moisture control in all manner of manufactured and natural CPG products, to look closer at what’s happening with cannabis once it leaves the cultivation room. There’s not a lot of research on cannabis storage—we checked—and so we explored this aspect further. We were frankly surprised by what a big effect evaporation has on quality and how this is playing out on the retail level.

We suspected moisture loss could affect the bottom line too, and so we did some number-crunching.

It’s well understood that the weight of cannabis flower directly correlates with its profitability—the heavier the yield, the higher the market value. Here’s what our analysis found: A mere 5% dip below the optimal relative humidity (RH) storage environment eliminates six pounds per every 1,000 pounds of cannabis flower. At $5 per gram wholesale, that works out to upwards of $13,500 in lost revenue—and that’s with just a 5% drop in RH below the target range of 55-65% established by ASTM International, an independent industry standards organization.

We also purchased flower at retailers in multiple state markets and commissioned a lab to test the samples, which revealed that most strains sold today are well below the optimal RH range (55-65%). Regardless of fluctuating wholesale prices, when you do the math it’s clear that tens of thousands of dollars in revenue are simply evaporating into thin air.

Why So Dry?

Historically, cultivators, processors and packagers have emphasized keeping flower below a particular humidity “ceiling” for a reason: Flower that’s too moist is prone to hazardous mold and microbial growth, so it’s understandable that many operators err on the side of being overly dry.

The misconception that cannabis flower can be “rehydrated” is another cause of dryness damage. But this method irrevocably damages the quality of the flower through trichome damage.

trichome close up
The fine outgrowths, referred to as trichomes, house the majority of the plant’s resin

Those delicate plant structures that house the all-important cannabinoids and terpenes become brittle and fragile when stored in an overly dry environment, and are prone to breaking off from the flower; they cannot not be recovered even if the flower is later rehydrated.

When trichomes are compromised, terpenes responsible for the aroma, taste and scent of cannabis also can evaporate. Overly dried-out cannabis doesn’t just lose weight and efficacy—it loses shelf appeal, which is particularly risky in today’s market.

Today’s consumers have an appreciation for how premium flower should look, smell and taste. Rehydration cannot put terpenes back in the flower, nor can it re-attach trichomes to the flower, which is why preservation of these elements is so key.

Cannabis Humidity Control

Cured cannabis flower can remain in storage potentially for months prior to sale or consumption. By the time it reaches the end consumer, much of the cannabis sold in regulated environments in the U.S. and Canada has suffered from dry damage.

There are various humidity controls available for cannabis cultivators: desiccants that absorb water vapor; mechanical equipment that alters RH on a larger scale; or two-way humidity-control packets designed for storage containers.

In the CPG sector, with other moisture-sensitive products such as foods and electronics, we’ve seen that employing humidity controls will preserve quality, and cannabis flower is no different.

Saltwater-based humidity control solutions with two-way vapor-phase osmosis technology automatically add or remove water vapor as needed to maintain a constant, predetermined RH level and ensures a consistent level of moisture weight inside the cannabis flower.

Here’s one more notable finding we discovered in our storage research: Third-party lab tests commissioned by Boveda showed cannabis stored with humidity control had terpene and cannabinoid levels that were 15% higher than cannabis stored without.

Cannabis stored within the optimal humidity range maximizes all the qualities that attract and retain customers. Similar to wine-making, when cannabis cultivators focus on quality control they need to look beyond the harvest.
