Film (gas barrier)
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.
Oxygen permeability (depends on humidity)
Nichigo G-Polymer exhibits excellent barrier performance in low humidity conditions.
