Applied on granule and powder, powder of plastic composite membrane pharmaceutical packaging bags are mainly are:
1, PVDC film: it is cut off a thin film of the best performance, and don't like PVC or EVAL by humidity the impact of changes like that, it has a good transparency and good heat cold resistance. PVDC latex can be as polypropylene film moistureproof coating, using it after coating of PT or good moistureproof OPP cut off performance and improve the drug packaging performance.
2, the two-way stretch polypropylene film: two-way stretch BOPP film has good transparency, heat resistance and good blocking resistance, suitable for composite bag outer, put it with LDPE, EVA, EEA, EAA that has good heat sealing quality and aluminum foil compounding, greatly improve the stiffness of the composite film and physical and mechanical properties. As in the paint membrane BOPP dampness barrier property excellent PVDC, is greatly improve the performance of it through.
3, flow extension polypropylene film: it has good heat sealing sex, more for the lining of the composite bags , aluminum vacuum plating again after and BOPP, PET, OPA, PT on composite.
4, polyester film: two-way stretch polyester film has a very high mechanical strength and rigidity, high heat resistance, resistance to drug performance is good, transparent and glossiness is very good, hydrosphere and oxygen through the sexual smaller, has the very good the sweet sex, it is all other film incomparable.
5, aluminized film: real aluminized film are high in vacuum condition aluminum steam precipitation accumulation to all kinds of the membrane of a thin film, al plating layer is very thin. Is now widely used have PETP, PT, PVC, CPP, OPP, PE and real aluminized film which use is more of PETP, CPP, PE vacuum coating aluminum film. Vacuum coating aluminum film characteristic, in addition to its characteristics of the basement membrane outside, still have beautiful decorative and better cut off performance, especially the base material of aluminium, light transmittance, through oxygen rate and through water vapor rate to decrease or one hundred times on a few times, can serve as a good materials used in medicine packing, is one of the excellent material focus on the futrue development.
