High isolation bags
- High isolation bag:
Its an excellent barrier against moisture, oxygen and light. Have a wide range of heat sealing temperature. The high isolation bags are not eroded by acid, alkali or sulfur. The bags are transparent and light without being fragile. The main materials are EVOH or film coated with PVDC. The materials coated with AL203 or SIO2 has almost the same functions as the aluminum foil, but they are transparent.
The different material structures are: KPET/CPP, KOPP/CPP, KPA/LDPE, M-PET/R-CPP, SIO2-PET/CPP ETC. Notice: K---PVDC, M-PET-PET coated with AL203.
