Problems solved by technology

However, when the indentation process is carried out on the printed matter after film coating, the paper surface of the printed matter is easy to break, resulting in a burst phenomenon, especially in the part where the pattern is a dark ink position, which affects the thermal lamination film used for the printed matter Durability and aesthetics, but also easy to cause partial separation of plastic film and printed matter, resulting in filming phenomenon

Abstract

The invention relates to the field of printed matter film covering, and particularly discloses a hot laminating film for printed matter and a preparation method of the hot laminating film. The hot laminating film for the printed matter comprises a substrate layer and an adhesive layer, wherein the adhesive layer comprises the following components: a mixed emulsion of polyvinyl acetate and a vinyl acetate-ethylene copolymer, a modified solution, an emulsifier, water, a defoaming agent, a tackifier, a wetting agent and a filler; the modified solution is prepared from N-hydroxymethyl acrylamide, isopropyl silicate and ammonium sulfate. The preparation method comprises the following steps: uniformly mixing a mixed emulsion of polyvinyl acetate and a vinyl acetate-ethylene copolymer with other formula components to obtain the bonding layer; corona treatment is conducted on the surface, bonded with the adhesive layer, of the base layer, the surface, subjected to corona treatment, of the base layer is coated with the prepared adhesive layer, and the hot laminating film for the printed matter is obtained after drying. The hot laminating film for the printed matter can be used for laminating the printed matter, and has the advantage of improving the line blasting phenomenon of the printed matter subjected to film laminating in an indentation process.

Description

technical field [0001] The application relates to the field of printed matter lamination, more specifically, it relates to a thermal lamination film for printed matter and a preparation method thereof. Background technique [0002] The film coating of printed matter is one of the processes in the post-printing process. By covering the surface of paper printed matter with plastic film, it can increase gloss, protect the surface, prevent ink from discoloration, decorate, chemical resistance, anti-counterfeiting and other functions. . [0003] Thermal lamination film is a commonly used lamination material in the lamination process. It usually includes a base layer and an adhesive layer. The base layer is a substantially transparent or translucent thermoplastic polymer material. When laminating the printed matter, the adhesive layer of the hot-mounted film is covered on the printed matter, and then the adhesive layer is activated by hot-pressing the hot-mounted film, so that th...
