Method for producing laser-type packing paper

Abstract

The utility model relates a production method of laser type tipping paper, which relates to the packing material technical field, in particular to an environmental protection-typed metallization packing material with a printing pattern. The invention comprises the following steps: a. coating: a PET plastic light film is adopted as basis material, a layer of high molecule resin material is uniformly coated on the basis material in advance, after being dried and solidified, a transparent surface coating with strippable performance is formed; b. molding: the surface of the PET plastic light film with a transparent surface coating is provided after being coated, a character and the pattern on a molding printing plate is transferred on the transparent surface coating under the pressure of 2 Kg / cm <2> to 4 Kg / cm<2>, the temperature of 160 to 180 DEG C and the speed of 35 to 45m / min, thereby generating a printing layer covered on the transparent surface coating, and forming a surface layer; c. aluminum coating; d. transferring. The invention aims at good anti-counterfeit effect and being easy to be largely produced.

Description

Technical field

[0001] The invention relates to the technical field of packaging materials, in particular to an environmentally friendly metalized packaging material with printed patterns. Background technique

[0002] Using vacuum aluminizing transfer technology to produce packaging materials and other papers is to heat aluminum with a purity of 99.9% to 1400-1500°C to evaporate, plate it on the carrier through condensation, and then transfer it to the paper to make the paper An ultra-thin aluminum film is formed on the surface. The thickness of the aluminum layer through vacuum aluminum plating is 0.02μm-0.04μm, which is only 1 / 200 to 1 / 300 of the thickness of the aluminum foil. This kind of vacuum aluminized transfer paper has a strong metallic luster in appearance, and is widely used in wine, cosmetics, supplements, food, medicine, especially the packaging of cigarette lining and outer shell. It consumes less materials and less waste. , Save resources and energy; easy to recy...
