SH-, SU-, SE- Series films are the transparent high gas-barrier films for food packaging. Nano-silica material is coated on base plastic films such as PET, OPP, OPA (Nylon), and hence the penetration of gases like oxygen or moisture is minimized. These SH-, SU and SE- Series high barrier film can be applicable to the food packaging, pharmaceutical packaging, cosmetics packaging, electronic parts packaging and other industrial packaging.
By minimized gas transmission, the shelf life of packaged food increases, and hence the production cost can be decreased.
Features
- Excellent Oxygen and moisture barrier,
- Aroma Preservataion
- Transparent
- Good printablility and Laminating machinability
- Eco-friendly (No emission of dioxin when burnt)
- Time-invariant transparency
- Excellent mechanical and optical property (Retains the properties and characteristics of base films)
