Problems solved by technology

[0003] However, the current pre-coating film substrates are mainly polyolefin films. Most of these films are non-degradable. From a long-term perspective, they are destructive to the environment. At present, the world's developed countries and the scientific and technological circles have unanimously advocated the use of environmentally friendly, non-toxic, non-polluting, fully biodegradable films that can eventually be degraded into CO2 and H2O to replace the existing plastic packaging films.

Abstract

The invention discloses a completely-biodegradable pre-coating film. The completely-biodegradable pre-coating film comprises a substrate, a middle layer and an adhesive layer, wherein the middle layer is positioned between the substrate and the adhesive layer; the substrate is prepared from the following materials in parts by weight: 1 to 10 parts of polyethylene terephthalate, 5 to 10 parts of biaxially oriented polypropylene thin film, 10 to 15 part of biaxially oriented polyester thin film, 1 to 5 parts of biaxially oriented nylon thin film and 1 to 4 parts of terpene resin; the middle layer is prepared from the following materials in parts by weight: 1 to 10 parts of polyethylene wax and 5 to 15 parts of elastomer; the adhesive layer is prepared from the following materials in parts by weight: 5 to 10 parts of ethylene-vinyl acetate resin, 1 to 5 parts of hydrogenated petroleum resin, 3 to 6 parts of hydrogenated rosin glycerol ester, 1 to 10 parts of petroleum resin and 1 to 10 parts of waterborne polyurethane. According to the completely-biodegradable pre-coating film disclosed by the invention, materials used by the completely-biodegradable pre-coating film have good biocompatibility, good biodegradability and good hot working performance of plastics, the completely-biodegradable pre-coating film is the first choice of biodegradable packaging materials, and the completely-biodegradable pre-coating film is better in biodegradability, quicker in degradation speed and more complete in degradation.

Description

technical field [0001] The invention relates to the technical field of precoating films, in particular to a fully biodegradable precoating film. Background technique [0002] Pre-coated film refers to the film formed by gluing and rewinding plastic film in advance and then compounding it with paper printed matter after heating and pressing. Pre-coated film is mainly used in books, packaging and digital printing. The printed matter after coating has a thin and transparent plastic film on the surface, which makes the surface smoother and brighter, thereby improving the gloss and fastness of the printed matter, making the graphic color more vivid, full of three-dimensional effect, and at the same time waterproof. Anti-fouling, wear-resistant, pleat-resistant, chemical corrosion-resistant, etc. [0003] However, the current pre-coating film substrates are mainly polyolefin films. Most of these films are non-degradable. From a long-term perspective, they are destructive to the ...
