[nanoPost] Film Provides Unprecedented Gas Barrier Properti

Transparent gas barrier film for retort food packaging. The film delivers outstanding gas barrier properties to meet the needs of the rapidly growing retort packaging market. Retort packaging offers manufacturers and consumers an appealing alternative to metal cans, with advantages that include higher food quality, more cost-effective shipping and superior shelf aesthetics.

The new film features a polyester (PET) film substrate with a coating layer based on nanotechnology. The film delivers outstanding oxygen barrier properties of less than 1cc/m2.day.atm, enabling packagers to eliminate metal foil layers from retort packaging, allowing for microwavability and improving environmental performance. The film also offers high transparency and retort resistance, maintaining excellent clarity through the retort sterilization process.

Key advantages of the film include:

Resistance to high-temperature pressure sterilization at 135 degrees C for 60 minutes
High gas barrier after retort treatment; less than 1 cc/m2.day.atm.
High transparency, before and after retort sterilization
Easy processing for lamination and printing
