EcoSafe® compostable resins are made of compostable biopolymers, PBAT and PLA. We do not put a product in market without industry-best testing and confirmation of compostability.

Sammy says: Hi Caitlin,
PLA is bio-based, derived from renewable resources like corn, sugar beets, and cassava. PBAT is fossil-based, made from petrochemicals like terephthalic acid, butylene glycol, and adipic acid. Both PBAT and PLA are biodegradable and compostable. PBAT is considered slightly more biodegradable than PLA. PLA is rigid with high tensile strength, similar to polypropylene (PP) or polystyrene (PS). PBAT is flexible and tough, with properties similar to low-density polyethylene (LDPE). Our high quality resins are designed for robust performance in applications where strength and elasticity are required, like carrying the very heavy and wet louds of food scraps for compost.

Caitlin Mahon says: What is PBAT and PLA made from? What is the original material used and are chemicals used? Thank you, Caitlin
Samantha says: Hi Richard,
Thanks for reaching out to us. EcoSafe® compostable bags, liners, and our other film products are produced from a certified compostable compound comprised of a copolymer called PBAT (polybutylene adipate terephthalate) and PLA (polylactic acid). This compound is partly biobased, and it is designed for robust performance in applications where strength and elasticity are required.
EcoSafe® compostable products are certified compostable to ASTM6400 standards, which validates compostability in industrial composting conditions, leaving no toxic residues behind.
By taking the extra step to ensure our compostable products are both BPI and CMA certified, our promise is to contribute to soil regenerative practices through the collection of food scraps for compost.
We have emailed you directly in case you have further questions.
Richard metz says: Hi folks,
Im with an environmental advisory group outside philadelphia, and chair of a plastics coalition here too
There’s been lots of discussion about the pluses and minuses of compostable bags. I need to know
Exactly whats in the bags- we need to research the chemicals to make sure they are non toxic and earth friendly. Thanks
What does it decompose into
How long does it decompose in a landfill?
What is PBAT and PLA? Thank you, Caitlin
