Abstract

The invention discloses an environmentally-friendly pre-coating film and a production method thereof. The environmentally-friendly pre-coating film comprises a hydrophobic and oleophobic layer, a baselayer, a base coating agent layer and a hot melt adhesive layer which are sequentially arranged from outside to inside, the hydrophobic and oleophobic layer is of a three-layer structure and comprises a nano-silica layer, a fluorosilane layer and a protective layer which are sequentially arranged from outside to inside, and the protective layer is composed of an acrylic resin, nano-silica, distilled water, an oxalic acid solution, a methylated hexamethylol melamine resin, an epoxy resin and ethanol; the base layer comprises polypropylene, ethoxylated alkylamine and ethoxylauric acid amine; the base coating agent layer is composed of an aqueous polyethyleneimine solution and alcohol; and the hot melt adhesive layer is composed of an ethylene-vinyl acetate copolymer, rosin, paraffin and anantioxidant. The bonding strength of the base layer and the hot melt adhesive layer is high, and the pre-coating film has diversified functions and a good protection effect.

Description

technical field [0001] The invention relates to the technical field of precoating film, in particular to an environment-friendly precoating film and a production method thereof. Background technique [0002] Pre-coated film is a kind of flexible packaging material for printed products. It is first coated with glue on the film by the pre-coated film processing factory according to the specifications and format, and then rewound for the manufacturer to choose, and then compounded with the printed matter. . The structure of the environmental protection pre-coating film in the prior art is generally composed of a base material and an adhesive layer, and often has the following problems: the base material is directly combined with the adhesive, and the bonding strength is low; the function is relatively single; and the protective effect is poor. Contents of the invention [0003] In view of the above-mentioned defects in the prior art, an object of the present invention is to ...
