Problems solved by technology

[0002] At present, in the pharmaceutical packaging market, the pharmaceutical packaging film prepared by general enterprises is composed of biaxially oriented polypropylene, aluminum foil and cast polypropylene, which has better barrier properties, but the cost is relatively high due to the use of aluminum foil. Although the cost of the packaging film made of polyester and polyethylene has been greatly reduced, its barrier property is poor, so the shelf life of the medicines in the package will be affected and the shelf life will be reduced.

Embodiment Construction

[0012] Below the present invention will be further described in conjunction with the embodiment in the accompanying drawing:

[0013] Such as figure 1 As shown, a high-strength and high-barrier pharmaceutical composite packaging film is composed of a biaxially oriented polypropylene film 1 and a vacuum aluminized cast polypropylene layer 3, and the vacuum aluminized cast polypropylene layer 3 is located on the biaxially oriented polypropylene film. Underneath the acrylic film 1, the vacuum aluminized cast polypropylene layer 3 and the biaxially stretched polypropylene film 1 are bonded together through an adhesive layer 2, and the adhesive layer 2 is Gaomeng 2501 aluminized glue. The thickness of the biaxially stretched polypropylene film 1 is 20 μm, and the thickness of the vacuum aluminized cast polypropylene layer 3 is 25 μm.

[0014] The vacuum aluminum-coated cast polypropylene layer 3 includes a cast polypropylene film 4 , and a layer of aluminum foil film 5 is vacuum c...

Abstract

The invention relates to a high-strength and high-barrier composite medicine packaging film comprising a biaxially oriented polypropylene film, an adhesive layer and a vacuum aluminizing casting polypropylene layer, wherein the vacuum aluminizing casting polypropylene layer is arranged below the biaxially oriented polypropylene film; the biaxially oriented polypropylene film and the vacuum aluminizing casting polypropylene layer are integrally bonded through the adhesive layer; the vacuum aluminizing casting polypropylene layer comprises a casting polypropylene film; an aluminum foil film is plated on the casting polypropylene film. The composite medicine packaging film is simple in structure, good in barrier performance and relatively low in cost; the shelf life of packaged medicine can not be affected, and the shelf life can not be shortened.

Description

technical field [0001] The invention relates to the technical field of composite flexible packaging, in particular to a high-strength and high-barrier drug composite packaging film, which belongs to the technical field of packaging materials. Background technique [0002] At present, in the pharmaceutical packaging market, the pharmaceutical packaging film prepared by general enterprises is composed of biaxially oriented polypropylene, aluminum foil and cast polypropylene, which has better barrier properties, but the cost is relatively high due to the use of aluminum foil. Although the cost of the packaging film made of polyester and polyethylene has been greatly reduced, its barrier property is poor, so the shelf life of the medicines in the package will be affected and the shelf life will be reduced. Contents of the invention [0003] The purpose of the present invention is to overcome the above disadvantages and provide a high-strength and high-barrier drug composite pa...
