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.
