Biodegradable packaging materials in 2026 and what packaging teams should verify
The short answer for 2026
Biodegradable packaging materials are not one material category, and they should not be treated as packaging that simply disappears after use. For packaging teams, the practical question is narrower: is the finished item certified for a defined end-of-life route, accepted by the relevant local waste system, and fit for the product it has to protect?
Compostable films, molded fiber, starch blends, PLA, PHA, coated paper and cellulose-based materials can all be useful, particularly in applications where food residue makes conventional recycling difficult. Broad biodegradable claims, however, create risk if they are not supported by testing, certification and clear disposal instructions. For more packaging industry updates, see the packaging materials section.
What biodegradable really means
Biodegradable describes a process: microorganisms break a material down under certain environmental conditions. It does not automatically mean a package will break down quickly in a landfill, home compost bin, ocean, soil or recycling stream. Temperature, moisture, oxygen, microbial activity, product thickness, additives and the surrounding waste system all affect the outcome.
Packaging teams should keep three terms separate, even though they are often combined in marketing copy:
- Biobased means the material is made partly or fully from renewable biological resources. It may still behave like conventional plastic if its polymer structure is similar.
- Biodegradable means the material can be biologically degraded under specified conditions. The claim is incomplete without the conditions and timeframe.
- Compostable means the material is designed to biodegrade in a composting process and leave compost that meets safety and quality requirements. Compostable packaging is biodegradable, but not all biodegradable packaging is compostable.
The U.S. Environmental Protection Agency makes this distinction in its public guidance on plastic recycling and composting. The European Commission has also warned that biobased, biodegradable and compostable plastics can mislead buyers and consumers when the terms are used without context.
Common biodegradable packaging materials and where they fit
The most useful way to compare biodegradable packaging materials is by application, waste route and verification requirement. A resin name is not enough. The finished package may include coatings, inks, adhesives, labels or barrier layers that change its end-of-life result.
| Material family | Typical packaging uses | Important checks |
|---|---|---|
| PLA and PLA blends | Clear cups, thermoformed trays, films and food-service packaging | Usually requires industrial composting. Check finished-item certification, heat resistance and whether local composters accept it. |
| PHA | Films, coatings, molded items and specialty packaging | Can offer broader biodegradation profiles than some other bioplastics, but claims must be specific to the grade, format and test method. |
| Starch blends | Bags, loose-fill packaging, flexible films and liners | Often blended with other polymers. Confirm mechanical strength, moisture sensitivity and certification for the final product. |
| Molded fiber and bagasse | Trays, clamshells, inserts, bowls and protective packaging | Fiber may be compostable, recyclable or both depending on coatings, food residue and local systems. PFAS and barrier additives require attention. |
| Cellulose-based films | Transparent wraps, windows, labels and flexible packaging | Coatings and lamination can determine whether the film is compostable, recyclable or unsuitable for either stream. |
| Coated paper and paperboard | Cups, cartons, wraps, mailers and pouches | Paper content does not guarantee recyclability or compostability. Verify coating type, repulpability, compostability and food-contact requirements. |
Packaging remains one of the main demand areas for bioplastics. European Bioplastics’ 2025 market update, as reported in industry coverage, identified packaging as the largest application segment for bioplastics. That does not mean every bioplastic package is environmentally preferable. It means packaging is where many technical and regulatory decisions are now concentrated.
Standards and claims matter more than the word biodegradable
For buyers, standards and certifications are more useful than broad material descriptions. The item that needs verification is the finished package, not only the resin or sheet supplied before conversion.
ASTM standards in North America
ASTM D6400 is widely used for plastics designed to be aerobically composted in municipal or industrial composting facilities. ASTM D6868 applies to certain products where biodegradable plastic films or coatings are attached to paper or other compostable substrates. ASTM D8410 addresses cellulosic-fiber-based packaging materials and products for compostability in municipal or industrial aerobic composting facilities. These standards apply to defined composting conditions, not uncontrolled disposal.
EN 13432 in Europe
EN 13432 is the key European standard for packaging recoverable through composting and biodegradation. It addresses biodegradation, disintegration, heavy metals and compost quality. A package that meets an industrial composting standard should not automatically be described as home compostable, because home composting normally operates at lower and less controlled temperatures.
Third-party certification
Third-party certification can reduce uncertainty, but the scope of the certificate matters. BPI’s North American program is based on ASTM compostability standards and distinguishes commercial compostability from home compostability. In Europe, certification marks such as OK compost INDUSTRIAL or OK compost HOME are commonly used to signal the relevant composting environment. Buyers should check whether the certificate covers the exact item, thickness, printing, additives and brand configuration being purchased.
Marketing claims in the United States
The Federal Trade Commission’s Green Guides remain a central reference for U.S. environmental marketing claims. The guidance warns against broad unqualified claims such as green or eco-friendly and says compostable and degradable claims need competent and reliable scientific evidence. For packaging likely to end up in landfill, incineration or recycling, unqualified biodegradable claims are especially difficult to support.
Regulatory pressure is changing the buying question
Packaging regulation is moving from general sustainability language toward measurable design, labeling and end-of-life requirements. In the European Union, Regulation (EU) 2025/40 on packaging and packaging waste entered into force on February 11, 2025, and began applying in phases from August 12, 2026. The regulation pushes packaging toward recyclability, waste prevention, recycled content in plastic packaging and clearer labeling over the coming years, with important milestones around 2030 and beyond.
This matters for biodegradable packaging because compostability is not a universal substitute for recyclability. A compostable format may be appropriate where the package is normally contaminated with food and can be collected with organic waste. It may be a poor fit for clean rigid packaging where recycling systems already work. Under the EU framework, the European Commission has also emphasized that biodegradable and compostable plastics should be used where they provide a clear benefit and where proper collection and treatment infrastructure exists.

Waste data help explain the policy pressure. The U.S. EPA’s latest national municipal solid waste factsheet series is still based on 2018 data and shows containers and packaging at 82.2 million tons, or 28.1 percent of U.S. municipal solid waste generation. In Europe, Eurostat reported in October 2025 that plastic packaging waste generation reached 35.3 kilograms per person in 2023. These figures are not arguments for one material by themselves, but they show why regulators are asking for better proof of packaging performance.
A practical verification checklist for buyers
Before selecting biodegradable packaging materials, packaging teams should treat end-of-life as a design requirement, not as a label added after production.
- Define the expected waste route. Decide whether the package is meant for industrial composting, home composting, recycling, reuse, landfill diversion through organics collection or another managed route.
- Confirm local acceptance. A certified compostable package may still be rejected by a local composting facility if the facility does not accept look-alike packaging or if processing time is too short.
- Request finished-item certification. Resin certification is not enough when converters add coatings, pigments, inks, adhesives, labels or closures.
- Check product protection first. Shelf life, moisture barrier, grease resistance, oxygen barrier, sealing performance and shipping durability can outweigh material claims if packaging failure increases product waste.
- Review food-contact and restricted-substance requirements. For food packaging, confirm applicable food-contact compliance and ask about intentionally added PFAS or other substances of concern.
- Use precise labeling. Labels should say whether the item is commercially compostable, home compostable, recyclable or not accepted in curbside recycling. Avoid stacking multiple claims unless each claim is true and clear.
- Compare alternatives. In some applications, lightweight recyclable paperboard, reusable packaging, recycled-content plastic or right-sized corrugated packaging may be a better fit than a compostable bioplastic.
Limits and trade-offs to keep in view
Biodegradable packaging materials are useful only within a system. If compostable packaging is placed in a plastics recycling bin, it may become contamination. If recyclable packaging is placed in an organics bin, it can contaminate compost. If biodegradable packaging is littered, there is no reliable guarantee that it will disappear quickly or harmlessly in the open environment.
Landfills are another limitation. Many compostable materials are designed for aerobic composting conditions, not the low-oxygen conditions common in landfills. The benefit of compostable packaging is strongest when it helps capture food scraps and moves both the food residue and the package into a suitable composting stream.
Cost and feedstock questions also matter. Biobased materials can reduce reliance on fossil feedstocks, but land use, agricultural inputs, manufacturing energy, transport and conversion losses should be considered. For fiber packaging, coatings that improve grease and moisture resistance can also make recycling or composting more difficult. The best choice is rarely decided by one attribute.
Frequently asked questions
Are biodegradable packaging materials the same as compostable packaging?
No. Compostable packaging is a specific category of biodegradable packaging designed to break down under composting conditions and meet compost quality requirements. Biodegradable is broader and should always be qualified by environment, timeframe and test method.
Can biodegradable packaging go in recycling?
Only if the package is accepted by the relevant recycling system. Many compostable plastics should not be placed in conventional plastic recycling because they can contaminate recycled material streams. Always follow the package label and local collection rules.
Is home compostable the same as industrially compostable?
No. Industrial composting uses more controlled conditions and higher temperatures. Home composting is cooler and less predictable, so a package certified for industrial composting should not be marketed as home compostable unless it has separate evidence for that claim.
What certification should buyers request?
For North American commercial compostability, buyers commonly look for certification based on ASTM D6400, D6868 or other applicable ASTM standards. For Europe, EN 13432 is a key packaging standard. The certificate should cover the exact finished item, not only a base material.
Are biodegradable materials always better than recyclable packaging?
No. They can be better in targeted uses, especially food-contaminated packaging that supports organics collection. For clean and widely recycled formats, recyclable or reusable packaging may be the more practical choice. The right decision depends on product protection, local infrastructure and verified end-of-life performance.
