Abstract

The invention provides a polyolefin film, an all-plastic composite film containing the polyolefin film and a preparation method and application of the all-plastic composite film. The polyolefin film comprises a corona layer, a middle layer and a heat sealing layer which are sequentially stacked. The heat sealing layer comprises metallocene linear low density polyethylene with the mass fraction of10-30% and a cycloolefin copolymer with the mass fraction of 70-90%. The all-plastic composite film comprises a printing layer, a light blocking layer and a polyolefin film layer which are sequentially stacked. Through reasonable modification of the polyolefin film heat sealing layer and the structure of the polyolefin film heat sealing layer, the adsorption capacity of the polyolefin film to a liquid medicament is relatively low, and the all-plastic composite film prepared from the polyolefin film is small in size and light in weight, can guarantee the effectiveness of the medicament, and canmeet the requirements of high barrier properties such as light resistance and the like.

Description

technical field [0001] The invention belongs to the field of food and drug packaging materials, and in particular relates to a polyolefin film, an all-plastic composite film containing the same, and a preparation method and application thereof, in particular to a polyolefin film used for flexible packaging of liquid medicines, and an all-plastic composite film containing the same. Composite membrane and its preparation method and application. Background technique [0002] Drug packaging materials refer to packaging materials and containers that directly contact drugs, mainly including bottles, bags, inner plugs and other containers made of various materials, as well as fillers and liners that touch drugs. Since pharmaceutical packaging materials are accompanied by the whole process of production, distribution and use of pharmaceuticals, factors such as the material composition, formula and production process of pharmaceutical packaging materials have become potential factors...
