Embodiment Construction

[0022] The manufacturing method of a kind of novel environment-friendly vacuum reflective material paper provided by this embodiment comprises the following steps:

[0023] A. Prepare aluminized base paper for copper plate and BOPP laser film with anti-counterfeiting grating. The BOPP laser film is formed by laser molding of ordinary BOPP film;

[0024] B. Paste the BOPP laser film on the transparent laser transfer paper, then compound the base paper and the BOPP laser film through the water-based acrylic polyol emulsion, and separate the base paper and the BOPP laser anti-counterfeiting film through the peeling and drying equipment to complete the anti-counterfeiting of the base paper on the BOPP The grating copy of the laser film makes the base paper have a grating; the peeled BOPP anti-counterfeiting laser film can be recycled to reduce waste; the moisture content of the peeling and drying is controlled at 2.8-3.6%, and the drying oven is a multi-stage oven. 80°C, 90°C, 95°...

Abstract

The invention discloses a method for manufacturing novel environment-friendly vacuum reflection material paper. The method comprises the following steps of: A, preparing raw paper and a BOPP (Biaxially-Oriented Polypropylene) laser thin film with an anti-counterfeiting grating; B, compounding the raw paper and the BOPP laser thin film through aqueous acrylic acid polyhydric alcohol, and then separating the raw paper from the BOPP anti-fake film; C, carrying out paper zinc sulfide evaporation on the raw paper with the copied grating through vacuum plating medium equipment; D, coating an aqueous crylic acid polyhydric alcohol transparent coating on the zinc sulfide surface of the raw paper evaporated with zinc sulfide through a coating machine; E, reversing the raw paper coated with the aqueous acrylic acid polyhydric alcohol transparent coating; and F, carrying out paper cutting and packaging and putting in storage after reversing. According to the method provided by the invention, the raw paper is provided with the anti-counterfeiting grating, so that the raw paper has a transparent radial anti-counterfeiting effect. The effects of the prior art can be reached by only printing ordinary transparent oil ink, so that the process of coating a film after printing can be eliminated, so that a label is anti-counterfeiting and environment-friendly.

Description

technical field [0001] The invention belongs to a reflective material paper, in particular to a method for making vacuum reflective material paper used for labeling food containers. Background technique [0002] In the prior art, the printing process of most food container labels, especially anti-counterfeit food container labels, is: firstly print the pattern on the copper plate, and then compound the laser-coated zinc sulfide film on the printed product through hot-melt self-adhesive, To achieve the anti-counterfeiting effect of the product. This process brings hidden dangers to food packaging because the composite hot melt adhesive often has VOC gas residues. In addition, the plastic film covered on the surface of the printed product is difficult to degrade when it returns to nature, which will cause pollution and damage to the natural environment. Contents of the invention [0003] The purpose of the invention is to provide a new type of environmentally friendly vac...
