Method for manufacturing metal-like packing paper

Abstract

The invention discloses a method for manufacturing metal-like packing paper, which comprises the following steps sequentially: (1), coating a metal printing ink on the paper base of the packing paper; (2), laminating the surface, which is coated with the metal printing ink, of the paper base of the packing paper with a thin film; and (3), after laminating, drying the metal printing ink, and separating the packing paper from the thin film to obtain the metal-like packing paper. The technical flow of the invention is simple and crafty; the cost is low; and the metal-like packing paper with goodsurface flatness, high brightness and holographic effect can be obtained.

Description

technical field

[0001] The invention belongs to a production method of wrapping paper, in particular to a production method of wrapping paper with metallic texture. Background technique

[0002] Metallic wrapping paper (referred to as "metallic wrapping paper") is widely used as the inner lining paper of cigarettes, tea leaves, chewing gum, etc. Most of the existing wrapping papers with metallic texture are silver, and a few are golden luster. They all form a metal material layer on the surface of the paper base. There are mainly the following production methods:

[0003] 1. Aluminum foil composite method: directly composite aluminum foil on the paper. The biggest disadvantage of this method is that the thickness of the aluminum foil is large, the amount of aluminum material is large, and the cost is high. It has been phased out;

[0004] 2. Transfer coating metal ink method: that is, coat a layer of metal ink on the roll film substrate, and the metal ink is also required t...

[0023] figure 1 As shown, the production method of the metal texture wrapping paper comprises the following steps in sequence: (1), the wrapping paper unwinding mechanism 1 unwinds the wrapping paper base 11, and coats the surface of the wrapping paper base with UV silver by the coating mechanism 2. Ink (so-called UV silver ink, is exactly the silver ink that solvent is UV oil); Laser film unwinding mechanism 5 will be printed with the laser film 12 of holographic concave-convex pattern unwinding; (2), wrapping paper base 11 is coated with UV The surface of the silver ink is pressed with the laser film 12 printed with holographic concave-convex patterns, so that the surface of the UV silver ink produces holographic concave-convex patterns; 6 apply pressure; (3), after pressing, utilize ultraviolet lamp 7 to irradiate, make the UV oil solvent in the UV silver ink dry (cure) immediately after irradiating, then wrapping paper 11 paper bases and laser film 12 are peeled off, obtai...

[0026] The production method of the metal texture wrapping paper comprises the following steps in sequence: (1), coating the silver ink containing aqueous solvent on the surface of the wrapping paper base; (2), smoothing the surface and the surface of the wrapping paper base coated with the silver ink Film pressing, after pressing, the composite material of wrapping paper base and film is sent to an oven for drying; (3), the film and wrapping paper base are peeled off to obtain a mirror-like smooth surface with bright silver luster Wrapping paper, finally rewinding the wrapping paper.

[0027] In the step (2) in the above-mentioned embodiment 2, an oven may not be used, and after the composite material of the wrapping paper base and the film is naturally dried, step (3) is performed to peel off the film and the wrapping paper base.

[0028] In the above examples, the silver ink containing the aqueous solvent can also be changed to the gold ink containing the aqueous solvent, s...
