It mainly takes PVC film as the basal material, then coated PVDC(import from BASF in Germany). During the production processing, the temperature, coated quantum, times and other important considerations are checked strictly to make sure that the product can meet the standard of the same product in the internatiolal. The obstruct ability is 5 times higher than common PVC. Meantime it has a certain rigidity, flexility 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 PVC film that widespread used in China could infiltrate the gas and liquor 6 months later in the boom temperature condition. It has a great impact on products. But if using PVDC, the period for protection can really reach at least 2 years.
