Problems solved by technology

[0004] There are obvious deficiencies in this structure and production and processing technology: (1) After the aluminum foil is dried at a high temperature of 200 ° C, for products that require cursor positioning and cutting, the cursor will be elongated, which is not conducive to cutting; (2) Using two-component solvent-based adhesives, there will be a large amount of organic solvent emissions during compounding, which is not conducive to environmental protection, or solvent recovery equipment needs to be added, which will increase additional costs

Embodiment 1

[0042] The present invention provides an aluminum-plastic cover film for blister packaging that is easy to position and cut with the cursor, comprising a cover film body 1, and the cover film body 1 sequentially includes a two-component protective coating 11, an ink layer 12, and a primer layer 13 , aluminum foil layer 14, adhesive layer 15, puncture strength enhancement layer 16, the two-component protective coating 11;

[0043] Wherein, the ink layer 12 includes a cursor pattern;

[0044]The material of the two-component protective coating 11 is polyurethane cross-linking reaction type, including the main agent polyol and curing agent isocyanate prepolymer, the main agent polyol and curing agent isocyanate prepolymer are sequentially mixed, Coating, oven drying, and cross-linking reaction curing form the two-component protective coating 11 , and the temperature of each process is lower than 100° C. to protect the cursor pattern from deformation. After the main agent polyol ...

Embodiment 2

[0055] The invention provides a method for preparing an aluminum-plastic cover film for blister packaging that is easy to position and cut with a cursor, comprising the following steps:

[0056] S1. Unwind the aluminum foil layer 14 with a thickness of 20-30 μm, apply a two-component primer on one side of the aluminum foil layer 14 with a coating thickness of 0.6-1.0 μm, and dry it in an oven at 40°C-80°C for 2-5 seconds, placed at a temperature of 18-22°C for 5 days, a cross-linking reaction occurs, and an undercoat layer 13 is obtained;

[0057] S2. According to the pattern setting requirements, make corresponding gravure rolls, cooperate with the ink to transfer on the primer layer 13, print the pattern on the aluminum foil layer 14 surface coated with the primer layer 13, and dry to get the ink layer 12, ink layer 12 has a thickness of 1-3 μm;

[0058] S3. After mixing the main agent polyol and the curing agent isocyanate prepolymer uniformly in a mass ratio of 100:8-14, ...

Abstract

The invention provides an aluminum-plastic cover film for blister packaging easy for cursor positioning and cutting. The aluminum-plastic cover film comprises a cover film body, wherein the cover filmbody sequentially comprises a two-component protective coating, an ink layer, a ground coat, an aluminum foil layer, an adhesive layer and a touch strength enhancement layer, the ink layer comprisesa cursor pattern, materials of the two-component protective coating are sequentially subjected to mixing, coating, oven drying and cross-linking reaction curing by a main agent polyhydroxy compound and a curing agent isocyanate prepolymer to form the two-component protective coating, all process temperatures are lower than 100 DEG C, and the cursor pattern is protected from deformation. The invention further provides a preparation method of the aluminum-plastic cover film for the blister package easy for cursor positioning and cutting. The double-component protective coating is adopted as a surface protective agent, the drying temperature is 65 DEG C-85 DEG C, the temperature of the entire manufacturing process does not exceed 100DEG C for the cover film body needing to be subjected to cursor positioning and cutting, and the shape of the cursor is not influenced by the elongation of the aluminum foil layer.

Description

technical field [0001] The invention relates to the technical field of medicine packaging, in particular to an aluminum-plastic cover film for blister packaging that is easy to position and cut with a cursor and a preparation method thereof. Background technique [0002] In the pharmaceutical packaging industry, aluminum-plastic blister packaging is widely used. This packaging is easy to carry, easy to take, and can guarantee the hygiene and shelf life of medicines to a certain extent, and is loved by most patients. [0003] The aluminum-plastic cover film with the structure of OP surface protectant / aluminum foil 20μm / PVC20μm is a commonly used material for blister packaging. Printing; (2) The semi-finished aluminum foil that has been printed is coated with OP surface protective agent and dried at 200°C; (3) The other side of the aluminum foil is coated with a two-component solvent-based adhesive and dried in an oven at 50-90°C , and then bonded with PVC for winding; (4) Af...
