Earthfirst® Biopolymer Films by PSI Launches Compostable Differential Sealing Temperature Overwrap Films

8 December 2021

Earthfirst® Biopolymer Films by PSI, a global manufacturer of biopolymer flexible packaging films, launched both home and industrial compostable overwrap films. Earthfirst® films are both sustainable and high performance.

The bio-based materials serve an increasing global demand for sustainable films that have a more positive environmental impact versus petroleum-based films. Earthfirst® films are greenhouse gas favorable to industry alternatives and compost into safe, natural and organic substances.

The films are an ideal fit for the diversity of flow wrap applications across food, retailer, bulk gift card/credit card fulfillment and many other consumer packaged goods (CPG) and industrial segments.

Film properties include a high outside/inside sealing differential, low seal initiation temperature and great seal integrity. These films can be printed Gravure, Flexo, Rotary UV Offset and Digital. Uniquely, the Home Compostable film has great versatility and can function as an overwrap, a sealant film and as a print web.

"Globally, our teams are dedicated to brands who are accelerating their adoption of sustainable films. Packaging transitions are increasing, and we fully support any incremental step to more environmentally positive  packaging," cites Michael DuFrayne, President and CFO. "We continue our commitment to sustainable film innovation."

The portfolio of Earthfirst® films are certified or in the process of certification by DIN CERTCO and TUV for compostability and the USDA BioPreferred® program for bio-content. All Earthfirst® films meet FDA standards for direct food contact.
