Extruded Films

Compostable Gas Barrier Film with Nichigo G-Polymer™

In low humidity conditions, Nichigo G-Polymer™ has the highest gas barrier performance of any thermoplastic resin.
In order to prevent loss of gas barrier performance in high humidity conditions, application of multiple layers is effective.
COMPOSTABLE AND HIGH GAS BARRIER FILM; Fully biodegradable barrier package material can be made by combination of biodegradable resin such as Poly Lactic Acid(PLA) and Poly Butylene Succinate (PBS), biodegradable adhesion resin (BTR8002P: produced by Mitsubishi Chemical) and Nichigo G-Polymer™ as an intermediate barrier layer.
