In order to provide the pharmaceutical market with more moisture protection, many enhanced performance protective ingredients can be added to PVC, polyester or other polymer substrates, such as PVdC (vinylidene chloride-based copolymer) coating film, it can provide high moisture-proof protection. Typically 40g, 60g and 90g/m2 coating weight on the market can lower the water vapor transmission rate (WVTR) from 0.6g/m2 to 0.2g/m2 .
The development of our new PVDC series products can improve the barrier performance of PVDC, which will have a high barrier to water and oxygen, and has a very good protection for pharmaceuticals. Until now, our per B series PVDC has been able to achieve water vapor barrier properties of less than 0.1g/m2 d.
