Problems solved by technology

[0004] The invention provides a frosted pre-coating film, which solves the problem that the current common pre-coating film has poor hand feeling and abrasion resistance, and cannot achieve anti-friction effect after being laminated with paper, causing the surface of printed matter to be easily scratched. , and the surface feels dry, which cannot improve the artistic effect of the printed matter, and realizes the technical effect that the surface of the printed matter has good anti-friction and anti-fouling properties and better decoration and protection on the surface of the printed matter

Embodiment 1

[0032] The frosted pre-coating film of the present embodiment comprises a frosted coating layer 1 formed on the substrate layer 2, the bottom of the substrate layer 2 is coated with a hot melt adhesive layer 3, and the pre-coated film is bonded with the printed matter through the hot melt adhesive layer 3 complex. The design of the matte paint layer makes the surface of the printed matter after the composite precoating film have better anti-friction and anti-fouling properties, so that the printed matter has a better use effect.

[0033] The frosted paint layer 1 is molded with a glare pattern, and the glare pattern includes a glare strip and a reflective strip with an artistic text effect, and the glare strip and the reflective strip can be correspondingly typeset according to the actual artistic effect requirements, so that Produce pre-coated films with different artistic effects. For example, the glare strips and reflective strips can be typeset into congratulations, bless...

Embodiment 2

[0044] The frosted precoat film of the present embodiment is basically the same in structure as in Example 1, the difference is that the thickness of the frosted paint layer is 4 μm; the material of the substrate layer 2 is a corona-treated BOPP film, and the substrate The thickness of the layer 2 is 15 μm; the material of the hot melt adhesive layer 3 is EVA, and the thickness of the hot melt adhesive layer 3 is 13 μm.

[0045] The preparation method of the frosted precoat film of this embodiment is the same as that of Embodiment 1.

Embodiment 3

[0047] The frosted pre-coating film of this embodiment is basically the same in structure as in Example 1, the difference is that the frosted pre-coating film also includes an undercoat layer formed between the substrate layer 2 and the hot-melt adhesive layer 3, the The solvent used for the primer layer is polyethyleneimine aqueous solution.

[0048]The thickness of the frosted paint layer is 3 μm; the material of the substrate layer 2 is a corona-treated BOPP film, and the thickness of the substrate layer 2 is 20 μm; the material of the hot melt adhesive layer 3 is EVA, the The thickness of the hot melt adhesive layer 3 is 15 μm.

[0049] The preparation method of the frosted precoat film of the present embodiment may further comprise the steps:

[0050] Substrate unwinding: select BOPP film as the substrate, and release the BOPP film with unwinding equipment;

[0051] Frosted pattern treatment: install the BOPP film with a thickness of 18μm and a width of 1080mm on the re...

Abstract

The invention discloses a frosted pre-coating and a preparation method thereof. The frosted pre-coating comprises a frosted paint layer and a substrate layer, the frosted paint layer is formed on thesubstrate layer, dazzle light patterns are pressed on the frosted paint layer, the bottom of the substrate layer is coated with a hot melt adhesive layer, the dazzle light patterns comprise a dazzle light strips and reflective strips, the dazzle light strips have artistic text effects. According to the frosted pre-coating, the substrate layer is coated with the frosted paint, the problem of poor appearance effect of the pre-coating is solved, the surface has uniformly frosted feeling after the frosted pre-coating and a printing product are compounded, the frosted pre-coating more has attraction, the substrate layer coated with the frosted paint layer, so that the surface of the printing product has better friction resistance and pollution resistance and effectively decorated and protected,and the frosted paint layer has dazzle light patterns, so that the frosted pre-coating has good artistic effects and identification.

Description

technical field [0001] The invention belongs to the field of coating films for printing, and in particular relates to a frosted pre-coating film and a preparation method thereof. Background technique [0002] Pre-coated film refers to pre-coating hot melt adhesive on the surface of the plastic film and then rewinding. The printing factory only needs to cover the pre-coated film on the printed matter, and adjust the laminating machine to a certain temperature and pressure, so that the pre-coated film is compatible with the printing. Paper glued together. The coated printed matter has a smoother and brighter surface due to the addition of a thin and transparent plastic film on the surface, thereby improving the gloss and fastness of the printed matter. Antifouling, abrasion resistance, folding resistance, chemical corrosion resistance, etc., are widely used in various types of paper printing such as packaging boxes, packaging bags, book covers, etc. [0003] Due to the conve...
