PVDC rigid sheet series for pharmaceutical packaging
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 .
