People today are more eco-conscious than ever. The last several years have seen a growing awareness of the impact of human behavior on the environment, and COVID-19 brought real-life context to the catastrophic effects of a global crisis. Lifestyle changes during the pandemic empowered people to make choices with a positive impact for the collective good. In a June 2021 PricewaterhouseCoopers survey , half of global consumers said they’ve become more eco-friendly since the COVID-19 pandemic. Consumers are changing their behaviors, educating themselves about the businesses they support, and evaluating the products they buy through a “green” lens. Terms like circular economy, zero-waste, ESG and carbon footprint are now part of the common vernacular, and sustainability is no longer a nice-to-have but a business imperative.

Cannabis consumers, in particular, value sustainability. They are conscientious of what they’re putting into their bodies and the planet. There is increased interest in brands and businesses that use responsible growing practices, eco-efficient manufacturing, and sustainable packaging. In a nationwide survey conducted by Canivate Growing Systems, 79% of U.S. cannabis consumers said they support establishing environmental standards. And in 2021, the Sustainable Cannabis Coalition (SCC) was formed to promote sustainability best practices.

Sustainable packaging is an important way that brands can show a commitment to the environment. Packaging is a highly visible and tangible representation of your brand and one that matters to consumers. A July 2021 Adweek/Morning Consult poll found that 77% of consumers believe it is the brand owners’ responsibility to make sure their packaging is recyclable. According to Nielsen, of the top five sustainability attributes consumers are willing to pay more for, three are packaging-focused: Recycled packaging, reduced packaging and reusable packaging. While cannabis packaging has unique regulatory requirements and safety guidelines, it can still be eco-friendly. Sustainable cannabis packaging has the necessary properties to protect against moisture and maintain freshness and smell. It can also be child-resistant and include other unique cannabis functionalities.

When it comes to sustainable cannabis packaging, that which you may believe to be the “greenest” option may not be sustainable at all. Many factors go into this determination, including packaging material, weight, distance traveled from supplier to manufacturer, water and energy usage and more. At Berlin Packaging , we take a comprehensive and integrated approach to sustainability to ensure our solutions meet customer objectives and consumer expectations. We use life-cycle analysis to quantify a product’s environmental impact throughout its entire life cycle, including sourcing/raw materials extraction, manufacturing, distribution and end-of-life. This analysis ensures that the solutions we provide are effective, impactful, and don’t contribute to greenwashing.

One key pillar of sustainable cannabis packaging is material circulation – using recycled and recyclable plastics and alternative materials. It’s important to understand that not all plastics are created equal. HDPE and PET are fully recyclable and have a ~30% recyclability rate. Polypropylene, on the other hand, while recyclable, only has roughly a 3% recyclability rate. Color can also play a role. PET is valued for its transparency, so colored and opaque plastics are not considered recyclable.

Continuous innovation and technological improvements have contributed to several eco-friendlier plastic packaging solutions. One popular choice for many of today’s brands is post-consumer recycled (PCR) materials. Using recycled plastic reduces single-use plastic waste that fills our landfills and threatens our waterways. Bio-plastics, made using renewable plant-based materials, are another sustainable option. Berlin Packaging has partnered with numerous premium packaging manufacturers to provide sustainable solutions for our customers. Many of our offerings – suitable for flower, pre-rolls, edibles, concentrates and more – can be produced using PCR or bio-plastics.

Material circulation means using recycled and recyclable plastics and alternative materials.

We’re also seeing brands embrace new compostable, biodegradable and paper packaging options. Berlin Packaging offers pre-roll tubes that are 100% compostable in industrial or municipal facilities and are better for the environment while also protecting the product inside. With zero migration, zero odor, and zero visibility, these air-tight tubes maintain freshness and meet regulatory requirements. We also offer a variety of paper tubes for pre-rolls, vape carts, and flower that are reusable, recyclable, and biodegradable.

Other sustainable packaging strategies include refill & reuse systems, which have gained popularity over the past several years, especially among personal care categories. Other tactics to consider when evaluating your package’s sustainability scorecard are eliminating unneeded packaging components like outer wraps and neck seals, ensuring labels are recyclable, and lightweighting (reducing the weight of your package). Berlin Packaging evaluates all of these avenues when developing sustainable packaging solutions.

Beyond the packaging itself, we encourage our customers to consider aligning their branding design and on-pack messaging to tell their sustainability story. We’re seeing many brands elevate their packaging sustainability benefits on their packaging’s primary display panel. The How2Recycle labeling program is another tool that helps educate consumers about how to dispose of packaging to ensure it gets recycled properly. Berlin Packaging’s sustainability specialists assist companies with comprehensive messaging strategies. Given the rise of greenwashing and consumer confusion and skepticism, effective and impactful messaging is a critical part of a sustainable packaging strategy.

Working with packaging suppliers and design partners who understand the cannabis market and have sustainability expertise is key to a brand’s success. A holistic approach that considers consumer insights, design functionality, aesthetics, manufacturability, regulatory requirements and sustainability results in packaging solutions that grow sales and build brand loyalty.

Sustainable Hemp Packaging is the Future of Industrial Packaging

The future of packaging is ripe for capitalization by the drivers of sustainability culture. With the battle lines drawn and forces at play in motion, change is now inevitable. The question arises: how quickly can the industry grow in the space of the next decade?

With an increasing number of nations banning non-biodegradable and petroleum-based plastics in certain uses, the choices at hand have naturally led to bioplastics. Bioplastics are a major ingredient of the renewable packaging industry. We derive them from various renewable agricultural crops, of which hemp is among the chief examples.

The Change for Hemp

The legal ramifications of the European Green Deal and the American Farm Bill of 2018 have created a microcosm where the sustainability discussion has turned into corporate initiatives for crops like industrial hemp, which are a source for bioplastics and numerous other products. The smaller carbon footprint of industrial hemp plays its role in shaping consumer demands towards a greener future.

Farmers are now able to cultivate the plant in the U.S., due to its removal from the list of controlled substances. Agribusinesses and manufacturers are aware of the plant’s versatility, with uses in packaging, building construction, clothing, medicinal oils, edibles like protein powder and hemp hearts, hemp paper and rope. What was once George Washington’s strong consideration as a cash crop for his estate, may gradually become the world’s cash crop of choice.

Hemp’s Sustainability Beckons 

Why is the crop unanimously superior in the aspect of eco-friendliness? Its growing requirements are frugal: water, soil nutrients and pesticides are not needed in large quantities. It absorbs great quantities of carbon dioxide from the atmosphere, and uses it to create 65-75% cellulose content within its biomass. Cellulose is vital in the manufacture of bioplastics. Hemp is also flexible within crop cycles, due to its small harvesting period of only 4 months.

Thus, farmers use it as a rotational crop, allowing them to also cultivate other crops after its harvest. High-quality crops like cotton, though superior in cellulose content and fibrous softness, require far more water quantities, soil nutrients and pesticides. Farmers face greater difficulties in cultivating cotton as a rotational crop, because it requires far more space and time.

Hemp Bioplastics For Packaging                                

We manufacture bioplastics from the hurd and cellulose of the hemp plant. Hemp bioplastics are biodegradable, and take up to a maximum of 6 months to completely decompose; by contrast, normal fossil-fuel-based plastic takes up to 1000 years to decompose.

Manufacturers incorporate these ingredients into existing manufacturing processes for regular plastics, such as injection molding. Thus, we can apply bioplastic ingredients to similar plastics applications, such as packaging, paneling, medical equipment and more. New technologies aren’t necessarily needed, so companies and manufacturers do not have any reservations about its viability as an industry.

Here are a few types of bioplastics derived from hemp:

  1. Hemp Cellulose-based Bioplastics

This is a substance found in plant cell walls. We use cellulose to manufacture a broad range of unique plastics, including celluloid, rayon and cellophane. These plastics are usually entirely organic. We mix cellulose and its variations (such as nanocellulose, made from cellulose nanocrystals) with other ingredients, such as camphor, to produce thermoplastics and the like. Using natural polymer, we process a broad range of bioplastics and corresponding polymers. The difference in their chemical properties is down to the nature of the polymer chains and the extent of crystallization.

  1. Composite Hemp-based Bioplastics

Composite plastics comprise organic polymers like hemp cellulose, as well as an addition of synthetic polymers. They also have reinforcement fibers to improve the strength of the bioplastic, which are also either organic or synthetic. Sometimes, we blend hemp cellulose with other organic polymers like shellac and tree resins. Inorganic fillers include fiberglass, talc and mica.

We call any natural polymer, when blended with synthetic polymers, a “bio composite” plastic. We measure and calibrate these ingredients according to the desired stiffness, strength and density of the eventual plastic product. Apart from packaging, manufacturers use these bioplastics for furniture, car panels, building materials and biodegradable bags.

A composite of polypropylene (PP), reinforced with natural hemp fibers, showed that hemp has a tensile strength akin to that of conventional fiberglass composites. Furthermore, malleated polypropylene (MAPP) composites, fortified with hemp fibers, significantly improved stress-enduring properties compared to conventional fiberglass composites.

  1. Pure Organic Bioplastics With Hemp

We have already generated several bioplastics entirely from natural plant substances like hemp. Hemp fibers, when made alkaline with diluted sodium hydroxide in low concentrations, exhibit superior tensile strength. We have produced materials from polylactic acid (PLA) fortified with hemp fibers. These plastic materials showed superior strength than ones containing only PLA. For heavy-duty packaging, manufacturers use hemp fibers reinforced with biopolyhydroxybutyrate (BHP), which are sturdy enough.

With the world in a state of major change due to the coronavirus outbreak of 2020, the focus is back on packaging and delivery. In this volatile area, perhaps the industry can learn a few new tricks, instead of suffocating itself in old traditions and superficial opportunism. The permutations and combinations of bioplastic technology can serve a swath of packaging applications. We must thoroughly explore this technology.

Hemp’s Future in Packaging

Fossil fuel-based plastic polymers are non-renewable, highly pollutive and dangerous to ecosystems, due to their lifespans. They are some of the most destructive inventions of man, but thankfully could be held back by this crop. Industrial hemp upheld countless industries through human history and now is making a comeback. After existing in relative obscurity in the U.S. due to false connotations with the psychoactive properties of its cousin, it is now back in business.

With the American hemp industry on the verge of a revolution, hemp packaging is primed to take over a significant part of the global packaging sector. The political, economic and environmental incentives for companies to adopt bioplastics are legion. Its lower cost lends to its allure as well. Consumers and agribusinesses are following suit, making the choice to be environmentally-conscious. By 2030, it is estimated that 40% of the plastics industry will be bioplastics.

We can only mitigate the plastic pollution in oceans, landfills and elsewhere, with the use of biodegradable bioplastics; otherwise, animals, humans and plants are getting adversely affected by imperceptible microplastics that pervade vast regions of the Earth. With hemp bioplastics, we use the cleaner, renewable matter of plants to conserve the planet’s sanctity. We can expect this new technology to continue to light the way for other nations, societies and companies to build upon this sustainable plan.
