Embodiment Construction

[0015] This embodiment produces the internal printing type vacuum aluminized transfer paper as shown in the accompanying drawing, and the specific steps are as follows:

[0016] a. Coating: Use uncorona-treated polymer PET or OPP plastic light film as the base material. On the base material, use coating equipment to coat a layer of polymer resin material evenly and appropriately, such as cellulose Resin or other resins, after being dried and solidified, form a layer of transparent surface coating 5 with peelable properties, the thickness of which is 0.5 μm to 1.5 μm;

[0017] b. Printing: use coating printing equipment to print characters or patterns on the surface of the coated transparent surface coating 5 to produce a printing layer 4 pasted on the transparent surface coating 5 to form a surface layer 6;

[0018] c. Aluminum plating: on the surface of the surface layer 6 printed with the printing layer 4, apply the vacuum aluminum plating technology to carry out aluminum pl...

Abstract

An internal-printing vacuum aluminum-coated transfer paper and its production are disclosed. The transfer paper consists of substrate, adhesive coating, aluminum coating and top coating, which comprise surface coating and printing coating. Printing coating is arranged at one side of top coating adjacent to aluminum coating. The process is carried out by coating stripped resin surface coating onto polymer light film, printing character pattern, vacuum aluminum coating to form aluminum-transfer film with internal printing pattern, combining with various papers, stripping light film from paper to obtain the final product. It costs low, has excellent printing effect and no environmental pollution.

Description

technical field [0001] The invention relates to the technical field of packaging materials, in particular to an environment-friendly metallized packaging material with printed patterns, in particular to an internally printed vacuum aluminized transfer paper and a production method thereof. Background technique [0002] Vacuum aluminum transfer technology is used to produce packaging materials and other types of paper, which is to heat aluminum with a purity of 99.9% to 1400-1500°C to evaporate it, and then coat it on the carrier (PET film) through condensation, and then transfer it to the paper. On the paper, an ultra-thin aluminum film is formed on the surface of the paper. The thickness of the aluminum layer by vacuum aluminum plating is 0.02 μm to 0.04 μm (the thickness of ordinary aluminum foil is 6 μm to 9 μm), which is only 1 / 200 to 1 / 300 of the thickness of the aluminum foil. This kind of vacuum aluminum-coated transfer paper has a strong metallic luster in appearanc...
