Abstract

The invention relates to a reversible photochromic composite packaging film for drug. The reversible photochromic composite packaging film comprises a two-way stretched polyester thin film layer, an aluminum foil and a casting polypropylene thin film layer which are arranged sequentially from top to bottom. The reversible photochromic composite packaging film is characterized in that the two-way stretched polyester thin film layer is connected with one side of the aluminum foil through a first polyurethane glue layer, the other side of the aluminum foil is connected with the casting polypropylene thin film layer through a second polyurethane glue layer; a reversible photochromic ink layer is printed on one side, in contact with the first polyurethane glue layer, of the two-way stretched polyester thin film layer. The two-way stretched polyester thin film layer is 12 mu m thick, the aluminum foil is 7mu m thick, and the reversible photochromic ink layer is 1-2 mu m thick. According to the composite packaging film, reversible photochromic ink is printed on a two-way stretched polyester thin film, then the two-way stretched polyester thin film, the aluminum foil and a casting polypropylene thin film are compounded through an adhesive so as to reach the purpose of reminding a consumer of selecting storage conditions, thus prolonging the shelf life of the drug.

Description

technical field [0001] The invention relates to a packaging film, in particular to a composite packaging film for reversible photochromic medicines, belonging to the technical field of pharmaceutical packaging films. Background technique [0002] At present, in the domestic drug packaging film market, there are many types of packaging material structures, such as transparent film structure, aluminized film structure, and aluminum foil material structure; no matter what material structure is used, drugs have a common barrier performance for packaging. Requirements, especially for light-sensitive drugs, there will be a storage requirement on the packaging instructions, such as shading, sealing, storing in a dry place, etc. Through research, the shelf life of general medicines will be greatly shortened when the light intensity is above 75 lx. Although there are storage instructions in this regard, most consumers do not know whether the environment they choose meets the requirem...
