Problems solved by technology

[0004] In the field of ultra-viscous and digital applications, high-demand patterns are usually covered with a film to improve the surface gloss and fastness of the product, prolong the service life of the product, and play a protective role in waterproof, anti-fouling, wear-resistant, and folding resistance. , and at the same time improve the aesthetics of product design; however, in the field of digital lamination, due to the picture effects such as frosting and unevenness required after cold pressing and hot pressing, ordinary laminations are prone to insufficient composite fastness, poor effects such as unevenness, etc., which affect the composite effect; the current forecast The use temperature of coated film products is generally high, which makes it easy to cause excessive heat shrinkage and wrinkles of the base film during the film coating process

Abstract

The invention discloses a coating type BOPP pre-coating film capable of embossing. The coating type BOPP pre-coating film comprises a base material layer, a hot melt adhesive layer and a coating layer which are arranged in sequence, the hot melt adhesive layer is prepared from the following raw materials: an ethylene-vinyl acetate polymer and N, N-4, 4-diphenylmethane type bismaleimide resin; the coating layer is prepared from a modified polyurethane solution, and the modified polyurethane solution is prepared by reacting the following raw materials in a solvent: a polyurethane prepolymer, dimethyl triphenyl ethane sulfonic acid isocyanate and maleic anhydride. The invention also discloses a preparation method of the pre-coating film. The technical problems that in the prior art, a common coating film is insufficient in binding force and compounding fastness and high in use temperature are solved, and the compounding fastness of the prepared pre-coating film and paper can be remarkably improved.

Description

technical field [0001] The invention relates to the technical field of films, in particular to a coating type BOPP embossable pre-coating film and a preparation method thereof. Background technique [0002] Pre-coated film refers to the process of pre-gluing and rewinding the plastic film, and then compounding it with the paper print. Generally, the pre-coating film processing factory first coats the glue on the film and rewinds it for the manufacturer to choose according to the specification and width, and then compound it with the printed matter. [0003] And laminating, that is, sticking film, is to coat the plastic film with an adhesive, and then heat and pressurize the paper printed matter to bond it together to form a processing technology of paper-plastic integrated product. There is an additional layer of thin and transparent plastic film, the surface is smoother and brighter, thereby improving the gloss and fastness of the printed matter, the color of the pictures ...
