Compostable vs. Recycled Plastic Film: Which Is Right for Your Brand?

In a world increasingly driven by sustainability, choosing the right packaging is more than just a materials decision—it’s a reflection of your brand’s values and long-term vision. Two popular options for mailers and flexible packaging are compostable plastic film and recycled plastic film. Both aim to reduce environmental impact, but they do so in very different ways.

So which one aligns best with your brand?

Compostable Plastic Film: Built from the Ground Up

Compostable films are made from plant-based or bio-derived materials such as PLA (polylactic acid), PBAT (polybutylene adipate terephthalate), or cellulose. These materials are designed to break down into non-toxic organic matter in a composting environment—ideally in industrial composting facilities.

Pros:

• Made from renewable resources, reducing dependency on fossil fuels.
  

• Leaves no microplastic residue when composted properly.
  

• Appeals to consumers seeking zero-waste or regenerative options.
  
  

Challenges:

• Requires access to commercial composting infrastructure, which is limited in many regions.
  

• Often not suitable for home composting due to temperature requirements.
  

• If sent to landfill or recycling, it does not break down properly and can contaminate recycling streams.
  
  

Recycled Plastic Film: Closing the Loop on Waste

Recycled plastic films are made from post-consumer or post-industrial low density polyethylene (LDPE) waste, giving existing plastic a second life. These films are often indistinguishable in performance from virgin plastic but come with a reduced environmental footprint.

Pros:

• Supports a circular economy by repurposing waste already in circulation.
  

• Familiar disposal method—many consumers recognize the recyclable label.
  

• Compatible with store drop-off recycling programs in the U.S. and some other countries.
  
  

Challenges:

• Curbside recycling doesn’t typically accept plastic films.
  

• Requires consumers to bring materials to specific drop-off locations.
  

• Still relies on fossil fuels as a feedstock and can contribute to long-term plastic pollution if mismanaged.
  
  

Infrastructure Reality Check

While both materials offer sustainable benefits, access to disposal infrastructure plays a major role in their real-world effectiveness:

• Compostable plastic is only beneficial if consumers have access to composting systems and know how to use them.
  

• Recycled film can only be processed through specialized thin-film recycling—mostly available via grocery store drop-offs.
  
  

In both cases, consumer education is critical. Packaging should include clear instructions and perhaps QR codes to direct users to nearby drop-off or composting sites.

Sustainability Footprint: Production vs. Disposal

While compostable plastic film has the appeal of being bio-based and made from renewable resources, its actual environmental footprint—especially in terms of global warming potential (GWP)—can be higher than both recycled and even virgin plastic.

• Compostable films require agricultural inputs (like corn or sugarcane), which involve fertilizer use, land change, and energy-intensive processing. The production phase typically results in higher GHG emissions, and if not composted properly, these materials may release methane in landfill conditions—further increasing their GWP.
  

• Recycled plastic films, by contrast, typically have the lowest carbon footprint of the three options. They avoid the impacts of virgin plastic production and leverage existing materials, resulting in significantly lower emissions—especially when made from post-consumer waste.
  
  

In other words, while compostable plastic film comes from nature, recycled plastic film makes better use of what's already here—and that matters when your brand’s goal is to reduce overall climate impact.

Customer Experience: Clarity Is Everything

Disposal can make or break the customer experience.

• Compostable packaging appeals to eco-conscious consumers—if it’s clearly labeled and supported by infrastructure.
  

• Recycled plastic film is more intuitive for many customers, but it’s not curbside-friendly, so the need to bring it to a store drop-off can be a hurdle.
  
  

To avoid confusion and frustration, brands must communicate not only how to dispose of packaging—but why it matters.

Finishes & Feel: The Aesthetic Side of Sustainability

Packaging isn’t just functional—it’s an extension of your brand. The look and feel of compostable vs. recycled plastic films can influence both customer perception and unboxing experience.

• Compostable Plastic Film often has a matte or frosted appearance and texture. It signals a more premium aesthetic.

• Recycled Plastic Film tends to be glossier and more transparent than compostable film, closer in appearance to conventional virgin plastic. However, it may include minor visual imperfections such as speckling due to the variability in recycled feedstock.
  
  

These differences aren’t just cosmetic—they can reinforce your brand values. A frosted compostable poly bag might appeal to earthy, natural-focused identities, while a glossy recycled film may better serve brands aiming for a sleek, modern, or tech-driven look while still reducing plastic waste.

Cost Considerations: Sustainability Comes at a Price

While both options aim to reduce environmental harm, compostable plastic film is generally more expensive than recycled plastic film—sometimes significantly so.

• Compostable films are made from bio-based materials that require agricultural production, specialized processing, and often smaller-scale manufacturing runs. These factors contribute to higher per-unit costs, which can be a barrier for brands with tight margins or high shipping volumes.
  

• Recycled plastic films, though still more expensive than virgin plastics, tend to be more cost-effective than compostables. They benefit from larger supply chains and existing manufacturing infrastructure, making them a more accessible sustainable option for many businesses.
  
  

That said, pricing continues to evolve as demand grows and technology advances. For some brands, the premium cost of compostables may be worth it for the narrative and mission alignment—but it's important to evaluate ROI carefully.

So… Which Is Right for You?

Both compostable and recycled plastic films offer sustainability benefits—but they solve different problems, and the right choice depends on your brand’s priorities, budget, and audience.

Choose compostable film if:

• Your brand values renewable inputs and a zero-waste narrative.
  

• You're targeting eco-conscious customers who value composting—and you're ready to provide education on proper disposal.

• You prefer a frosted, matte, or natural aesthetic that visually aligns with low-impact living.
  

• You’re willing to invest more per unit for packaging that makes a clear values statement, even with a higher climate footprint.
  
  

Choose recycled plastic film if:

• Your focus is on reducing global warming potential and supporting a circular economy.
  

• You want a lower-cost sustainable option that still significantly reduces reliance on virgin plastic.
  

• Your audience is more likely to use store drop-off recycling, or you plan to guide them toward those options.
  

• You prefer a glossy, transparent finish—with occasional visual imperfections—that feels closer to traditional plastic but with a sustainable edge.
  
  

Final Thoughts

Both recycled and compostable plastic films have the potential to drive meaningful impact—but their success depends on alignment between your values, your customers’ behavior, and the infrastructure available to support them. There’s no perfect solution, but with transparency and education, your packaging can be a powerful reflection of your commitment to sustainability.
