In practical application process, added non-toxic PVC monomer which has the environmental protection ability on the clear PET surface , combined with PVDC good obstruct ability , it plays a good moisture-proof effect to the product in packing.
    PVDC material itself is the latex character, has quite big brittleness after the solidification. In the coating process and post-processing, the pivotal technical is to reduce its brittleness, make it normally used in the room temperature environment. Before, the technical ability is too poor to do so. That is one of the technical difficulties of PVDC compound material.
    On the basis of oversea craft brother experience, our technician first produces successfully in China. It mainly takes PET film as the basal material, then coated PVDC(import from BASF in Germany). During the production processing, the temperature, coated quantity and times and other important considerations are checked strictly to make the final product meet the foreign products quality standards. The obstruct ability is 5 times higher than the common PVC. Meantime it has a certain rigidity, flexible and can be widely used in packaging various solid medicine, especially for easy humidity absorb medicine.

Remarks:
    According to the investigation, presently 80% medicine using such packaging materials, but the PVC film that widespread used in China could infiltrate the gas and liquor 6 months later in the room temperature condition. The product will cause toxic effects. At present, developed countries all forbid using PVC to contact medicine directly.
