Heat insulation plastic aluminum blending bag film coating material composition

Abstract

The invention provides a heat insulation plastic aluminum blending bag film coating material composition and relates to a plastic woven bag printing technology field. The composition is prepared from the following raw materials: 55-65 parts of polypropylene, 25-35 parts of low density polyethylene, 5-7 parts of linear polyethylene and 3-5 parts of ethylene-vinyl acetate copolymers. The beneficial effects are that the prepared film coating material is reasonable in matching, the technology is simple, the product package level is raised without increase of cost, and the film coating material composition has characteristics of heat insulation, anti-aging, good sealing, large tensile strength, high weatherability and the like.

Description

technical field [0001] The invention relates to the technical field of plastic woven bag printing, in particular to a heat-insulating plastic-aluminum composite bag coating material composition and a preparation method thereof. Background technique [0002] Plastic is a kind of polymer material. With the continuous development of polymer materials, the application of polymer materials is more and more extensive, such as "replacing steel with plastic" plastic gears, construction pipes, medical and auto parts, etc., plastic woven products composite The process is mainly to compound the surface of plastic woven products with film, or compound them with paper, film, and other materials, so that the woven products after compounding are weatherproof, moisture-proof, and air-tight. At present, composite plastic woven products in many industries in the market use kraft paper and various films, and the inner layer is artificially covered with inner film bags and aluminum foil bags.

Problems solved by technology

At present, composite plastic woven products in many industries in the market use kraft paper and various films, and the inner layer is artificially covered with inner film bags and aluminum foil bags. However, such inner films and papers have low sensory grades, poor heat insulation performance, and are easy to age. , poor sealing performance, low tensile strength, weak weather resistance, and the artificial sleeve plus lining film, aluminum foil, etc. are uneven, not stretched, not close to the inner wall of the outer bag, and the aluminum foil is not used as a composite material to directly coat the inner layer. Therefore, the use effect is extremely poor
