For this reason, PP and pet hard films are now available. At the same time, there are pvc/pvdc, pvc/cfe (C gives full play to its advantages fe-pct), pvc/pe/pvdc and other composite hard films that can retain the advantages of PVC hard films and overcome their shortcomings

pvdc and CFE have excellent gas barrier, with a thickness of 250 μ The moisture permeability of PVC hard sheet of M is 2.5g/m? 2·24h。 Compound a layer 30 μ After PVDC of M, its moisture permeability can be reduced to 0.3g/m? 2·24h。 As a single dose blister package, the other side is aluminum foil for drug packaging (commonly known as "PTP" aluminum foil). As the main material, metal aluminum should be completely isolated from light and gas. It is generally believed that the thicker the aluminum foil is, the smaller the pinholes will be. 2.
