nano composite film is a new high barrier aluminum free composite film developed by supertech, which contains inorganic high water resistance coating and organic high gas resistance nano coating. its excellent gas and water resistance performance makes it have ultra-high water vapor and oxygen barrier performance, and can be used in various packaging fields with high requirements for gas and water resistance.
【key features】：
---add self-developed nano high barrier coating film to make it have excellent performance
barrier (water, oxygen, light and moisture)
---when applied to vip, the thermal bridge effect can be avoided
---good weather resistance, can withstand low temperature freezing, refrigeration and transportation
---optimized composite structure after a large number of r & d tests
---cost effective
