Biodegradable Bags in Portland, ME
Portland, Maine has become one of America's most celebrated food cities — the Old Port's extraordinary concentration of James Beard Award-winning restaurants, craft breweries, artisan food producers, and creative businesses has made Portland a culinary destination that punches far above its weight for a city of 70,000. The city's thriving arts community, premium retail economy on Exchange Street and Congress Street, and a growing tech startup ecosystem create diverse packaging demand. My Custom Boxes serves Portland's creative and food-forward business community with premium custom packaging.

Why Choose Our Biodegradable Bags
Custom Biodegradable Bags | Plant-Based Sustainable Flexible Packaging
Biodegradable bags are manufactured from materials that undergo biological degradation through the action of microorganisms — bacteria, fungi, and algae — breaking complex polymer chains into simpler compounds including water, CO2, and biomass. Unlike conventional plastics that persist in the environment for hundreds of years, biodegradable packaging materials break down within months to years under appropriate conditions, significantly reducing the environmental persistence of packaging waste.
Biodegradable Materials
- PLA (Polylactic Acid): Derived from fermented plant sugars (corn, sugarcane) — compostable in industrial composting facilities certified to ASTM D6400
- PBAT (Polybutylene Adipate Terephthalate): Petroleum-derived but certified biodegradable — often blended with PLA for improved flexibility
- TPS (Thermoplastic Starch): Derived from potato or corn starch — highly biodegradable but sensitive to moisture
- PHB/PHA (Polyhydroxyalkanoates): Bacterial fermentation-derived bioplastics — home compostable and marine biodegradable in some formulations
- Cellulose Film: Wood pulp-derived transparent film — biodegradable and compostable, used as NatureFlex or similar brands
Important Distinction: Biodegradable vs. Compostable
Biodegradable means a material will eventually break down biologically — but without a timeframe specification or conditions definition. Compostable materials meet specific standards (ASTM D6400, EN 13432) that define the timeframe and conditions under which biodegradation occurs. Brands making compostable claims should use certified compostable materials to avoid greenwashing liability under FTC Green Guides.
Biodegradable vs. Compostable: Critical Distinction for Brand Claims
These terms are not interchangeable, and confusing them creates greenwashing liability. Biodegradable is a general claim that a material will eventually break down biologically — but 'eventually' can mean decades under landfill anaerobic conditions, which is not meaningfully different from conventional plastic. Compostable is a specific, testable, certifiable claim: ASTM D6400 certified materials biodegrade to 90% conversion in 180 days under industrial composting conditions. Brands making packaging sustainability claims must use certified compostable materials with certification documentation to make defensible FTC Green Guides-compliant claims.
Home Compostable vs. Industrial Compostable
Industrial compostable materials (ASTM D6400) require the elevated temperatures (55–60°C) and microbial conditions of industrial composting facilities to achieve certification-standard biodegradation. Consumer access to industrial composting varies dramatically by location — many areas have no municipal composting program. Home compostable materials (ASTM D6868 or OK Compost HOME certified) biodegrade under the ambient temperature and moisture conditions of a backyard compost pile — dramatically more accessible to end consumers and therefore a more genuine end-of-life solution for brands committed to circular economy packaging.

Biodegradable Bags in Portland — FAQs
What is the difference between biodegradable and compostable bags?
Biodegradable means a material will eventually break down biologically, but without a specified timeframe or conditions. This claim is too vague for FTC Green Guides compliance. Compostable (ASTM D6400 or EN 13432 certified) specifies that the material biodegrades 90% within 180 days under industrial composting conditions. Certified compostable is the substantiated, defensible claim; generic biodegradable is not.
Are PLA bags home compostable?
Standard PLA requires industrial composting temperatures (55–60°C) to biodegrade at certified rates — it will not reliably biodegrade in a home compost pile. PHA-based materials and some PLA/PHA blends are certified for home composting. For brands requiring consumer-accessible compostability, home compostable certified materials (PHA, or OK Compost HOME certified blends) are the appropriate choice.
Can biodegradable bags be printed?
Yes. Biodegradable and compostable bags are printed using water-based or bio-based inks that maintain the overall compostability certification of the packaging. Solvent-based inks can compromise compostability certification because the ink residue may not biodegrade within the certification standard's timeframe.
Do biodegradable bags have the same performance as conventional plastic?
Biodegradable bags made from PLA/PBAT blends have similar functional properties to conventional LDPE for most food and retail applications. Key limitations: PLA has lower heat resistance than conventional plastics (not suitable for hot food applications above 40°C), lower moisture barrier performance than LDPE, and higher cost. For most ambient temperature food and retail applications, the performance difference is manageable within the sustainability benefit.
