Problems solved by technology

[0002] The shrink film labels used in existing food containers are usually packaged by direct printing, which does not have anti-counterfeiting effects of gratings and partial metal gratings. The reason is that most of the existing grating technologies use high-temperature heat sealing and shaping of films The characteristics of low-temperature shrink film are just opposite to this performance, and it is not easy to realize. This makes how to realize the grating anti-counterfeiting performance of low-temperature shrink shrink labels has become a technical problem that needs to be solved urgently.

Embodiment 1

[0022] Embodiment 1, according to the first preparation method:

[0023] A method for making a low-temperature shrinkable film laser label material. (1) First wrap an anti-counterfeit grating laser BOPP film on the first unwinder, and coat the wound anti-counterfeit grating laser BOPP film with a mixture of environmentally friendly hydroxyl resin and isocyanate resin. The resulting solution, the mass ratio of environmentally friendly hydroxyl resin and isocyanate resin is 1:1.8; the coated anti-counterfeiting grating laser BOPP film is heated in an oven, and the temperature in the fourth section of the oven reaches 60°C-85°C-95°C- 85°C; the speed of the anti-counterfeit grating laser BOPP film is controlled at 100m / min when it passes through the oven; The synthetic material needs to be cured by heating again; (3) The cured composite material is separated from the low-temperature shrink film and BOPP laser anti-counterfeiting film by the stripping equipment, and the grating cop...

Embodiment 2

[0024] Embodiment 2, according to the first preparation method:

[0025] A method for making a low-temperature shrinkable film laser label material. (1) First wrap an anti-counterfeit grating laser BOPP film on the first unwinder, and coat the wound anti-counterfeit grating laser BOPP film with a mixture of environmentally friendly hydroxyl resin and isocyanate resin. The resulting solution, the mass ratio of environmentally friendly hydroxyl resin and isocyanate resin is 1:1.9; the coated anti-counterfeiting grating laser BOPP film is heated in an oven, and the temperature in the fourth section of the oven reaches 65°C-80°C-90°C- 90°C; the speed of the anti-counterfeit grating laser BOPP film is controlled at 90m / min when it passes through the oven; The synthetic material needs to be cured by heating again; (3) The cured composite material is separated from the low-temperature shrink film and BOPP laser anti-counterfeiting film by the stripping equipment, and the grating copy...

Embodiment 3

[0026] Embodiment 3, according to the first preparation method:

[0027] A method for making a low-temperature shrinkable film laser label material. (1) First wrap an anti-counterfeit grating laser BOPP film on the first unwinder, and coat the wound anti-counterfeit grating laser BOPP film with a mixture of environmentally friendly hydroxyl resin and isocyanate resin. The resulting solution, the mass ratio of environmentally friendly hydroxyl resin and isocyanate resin is 1:2; the coated anti-counterfeiting grating laser BOPP film is heated in an oven, and the temperature of the 4th section of the oven reaches 55°C-90°C-85°C-80°C ; The speed of the anti-counterfeit grating laser BOPP film is controlled at 110m / min when it passes through the oven; It needs to be heated and cured again; (3) The cured composite material is separated from the low-temperature shrink film and BOPP laser anti-counterfeiting film by the stripping equipment, and the grating copy of the low-temperature ...

Abstract

The invention discloses a manufacturing method for a novel low-temperature shrink film laser label material. The method comprises the steps that (1) an anti-counterfeiting grating laser BOPP film is wound around a first unreeling machine, a solution formed by mixing environment-friendly hydroxyl resin and isocyanate resin coats the wound anti-counterfeiting grating laser BOPP film, and the coatedanti-counterfeiting grating laser BOPP film is heated through a drying oven; (2) then a low-temperature shrink film on a second unreeling machine and the anti-counterfeiting grating laser BOPP film discharged from the drying oven are compounded, and a synthetic material needs to be heated and cured after being compounded; and (3) the cured composite material passes through stripping equipment to separate the low-temperature shrink film from the BOPP laser anti-counterfeiting film, and the low-temperature shrink film copies a grating of the BOPP anti-counterfeiting laser film. The manufacturingmethod has the advantages of being low in economic cost and free of secondary pollution to social environment.

Description

technical field [0001] The invention relates to a shrink film laser label material, in particular to a manufacturing method suitable for a low temperature shrink film laser label material. Background technique [0002] The shrink film labels used in existing food containers are usually packaged by direct printing, which does not have anti-counterfeiting effects of gratings and partial metal gratings. The reason is that most of the existing grating technologies use high-temperature heat sealing and shaping of films The characteristics of low-temperature shrink film are just opposite to this performance, and it is not easy to realize. This makes how to realize the grating anti-counterfeiting performance of low-temperature shrink shrink labels an urgent technical problem to be solved. Contents of the invention [0003] The purpose of the present invention is to provide a manufacturing method with reasonable technology and capable of processing shrink film laser label material...
