Melt-casting films
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.

Solution speed varies greatly depending on the film (plate) thickness, water solution temperature and
agitation method.
Sample: BVE8049P single layer film or plate (25×50 mm)
【Measurement method】
Films
and plates were immersed in agitated water controlled at each temperature, and to check the time until
it complete disolve.
Agitation: three-one motor at 300 rpm
