Biodegradable barrier package materials
Nichigo G-Polymer™ as a Biodegradable Barrier Packaging Material
Fully biodegradable barrier package materials can be designed by using Nichigo G-Polymer™ as an intermediate barrier layer and combining it with biodegradable resins such as polylactic acid (PLA) and polybutylene succinate (PBS) and a biodegradable bonding resin developed by Mitsubishi Chemical.
Nichigo G-Polymer™ is used as an intermediate layer (barrier layer) for biodegradable barrier packaging materials, as shown in the photo below.
Recommended grades when using Nichigo G-Polymer™ as a material for biodegradable gas barrier packaging
