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.

With the advent of new drugs  and detection trends have emerged (40°C - 75% RH), and additional barrier performance requirements have steadily increased.

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/m²d.
