High transparency and orientability grades G-Soarnol™

G-Soarnol™ is a special EVOH developed by Mitsubishi Chemical’s original technique which has controlled crystallinity and melting temperature.
G-Soarnol™ is a new type of EVOH s\which has both very good gas barrier property and thermoformability, orientability and transparency.
G-Soarnol™ is suitable for orientation and shrink film application and barrier packaging requiring high transparency.

Orientability with PP / G-Soarnol™ multilayer structure

Evaluate film appearance after orientation test by using G-Soarnol™ GH3804B and 44mol% EVOH.
G-Soarnol™ showed superior orientability to 44mol% EVOH which has better orientability in EVOH and kept good appearance.

Evaluation result in PP co-injection molding

Compare bottle appearance between 32mol% EVOH and G-Soarnol™ which is made by using Injection stretch blow molding (ISBM).
Since high orientability is required, processing with 32mol% EVOH is difficult but G-Soarnol™ makes it possible.
