inplasticpharmaceuticalpackagingmaterials.
Thecontrollablelistoftheadditivesincludedinthisstandardisasummaryoftheadditivesusedin
plastics,whicharespecifiedinthemainregulatorydocumentsathomeandabroad.
Thisstandardprovidesusemethodofadditivesusedinpharmaceuticalpackagingmaterialsfor
pharmaceuticalpackagingmaterialsmanufacturingenterprises.Theplasticmaterialsinclude
polyethylene(PE),polypropylene(PP),polyethyleneterephthalate(PET),polycarbonate(PC),cyclic
olefins(COC,COP,etc.),polyvinylchloride(PVC),polyvinylidenechloride(PVDC),poly(ethylene-
vinylacetate)(EVA),polyamide(nylonPA),etc.,andthecompositematerialsformedbycompounding
