1. PVC/PVDC, PVC/PE/PVDC composite sheets It consists of PVC, PVC/PE matrix layer and coated layer of PVDC held high barrier properties, which barrier properties is 5-10 times greaten than those of pure PVC sheet, because of effectively preventing medicine from humidity absorbing, they are ideal immaterial for medicine bubble packing, there fore the usable life of medicine could be prolonged. Resulted from PVC sheet which is medicine grade and PE protection film, the PVC/PE composite sheets are main used for liquid packing of little dosage, compared with glass contains, they have a series of merits, such as high strength, good sealing-ability, no fragility safe to transport, easy to take care of. 2. Specification: Thickness (mm): 0.10-0.35 Width (mm): optional Coating amount (g/m2): 40, 60, 90. Remark: according to requirements of clients, the color could be optional. 3. OPA/AL/PVC trinity composite material Because of excellent barrier properties, such as moisture proof, barrier to oxygen, light shielded, these products could effectively present deterioration of medicine ingredient from gas, perfume and other media. Of is specially suitable to packing of medicine which is prone to decompose on chemical react when contact with above media, including pellet, tablet, powder, tincture, capsule and surgical medicine, easy to open is another merit of such packing. Different from ordinary PVC sheet in forming, it not utilize heat forming but cold forming, so the hearing step in forming could be saved. Indeed, it is a advanced packing material for medicine.
