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 .
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/m2 d.
