Frequently Asked Questions: Compostable Blown Film Resin
What is compostable resin for blown film?
Compostable resin for blown film is a bio-based and plant-derived material engineered for flexible packaging film production. It is typically formulated using PLA, PBAT, and other proprietary compostable compounds designed to balance performance and biodegradability.
Our compostable resin compounds are developed to break down under industrial composting conditions (and selected grades under home composting conditions), where microorganisms, heat, and moisture help the material fully biodegrade into natural elements over time, without leaving harmful microplastics.
Despite being compostable, the material is engineered to maintain strong mechanical properties during its useful life, including tensile strength, flexibility, and reliable processing performance on standard blown film extrusion equipment. This makes it suitable for converting into high-quality packaging films and bags while supporting a more sustainable alternative to conventional plastics.
