The use of rigid polyvinyl chloride (PVC pharmaceutical rigid sheet ) as a means of protecting drugs has been established for many years. PVC is used in PTP Al/plastic packaging to provide consumers with a wide range of benefits such as product visibility, barrier and mechanical protection, ease of use and adaptability. Polymer monolayer polyvinyl chloride films are commonly used in less demanding applications such as small tablets and superficial tablets. The copolymer grade PVdC is recommended for more demanding applications such as large tablets (Drugs with high moisture absorption). To solve requirements such as product performance and protection, such as childproof packaging and UV protection products, PVC sheets can provide suitable solutions.

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.
