Biodegradable barrier package materials

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.

The table below lists recommended grades and corresponding products, MFR, and OTR for using Nichigo G-Polymer™ as a material for biodegradable gas barrier packaging. The corresponding product and MFR of biodegradable bonding resins are also listed. All grades are recommended for food package applications.

1): 2,160 gf, 210°C
2): 23°C, 65%RH
OKS: product under development

The numbers above are sample values, and are not guaranteed.

Nichigo G-Polymer™ BVE8049P, AVE8077P, OKS-8074P, and biodegradable bonding resin G-Connect™ BTR8002P have acquired the EU biodegradability certification of “OK compost” and US biodegradability certification.

The table below lists the oxygen permeability of Nichigo G-Polymer™ when used as a material for multilayer containers.
