Efficient-printing polyethylene film material for toothpaste sheet and preparation method of polyethylene film material

Abstract

The invention discloses an efficient-printing polyethylene film material for a toothpaste sheet, wherein the polyethylene film material comprises the following materials in parts by weight: 60-70 parts of linear low density polyethylene, 8-15 parts of waxy corn starch, 8-15 parts of plant fiber powder, 3-6 parts of silane coupling agent, 25-35 parts of degradation type calcium carbonate masterbatch, 10-18 parts of vinyl-terminated silicone oil, 0.3-0.8 part of silicone oil containing hydrogen, a proper amount of sulfuric acid solution, a proper amount of platinum catalyst, 2-5 parts of maleic anhydride, and 0.5-1 part of sorbic acid. The polyethylene film material, after being used, is degraded into water and carbon dioxide under the natural conditions within 6-18 months, the biodegradation is fast, no white pollution is caused, and the requirement of environmental protection is met; in addition, due to the addition of the maleic anhydride and the sorbic acid, the compatibility of the polyethylene and a calcium carbonate particle is strengthened, the roughness is improved, the binding power between the surface of a polyethylene film and printing ink is improved, and efficient printing is achieved.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a polyethylene film material with high-efficiency printing effect for toothpaste sheets and a preparation method thereof. Background technique [0002] Toothpaste tube packaging currently mainly uses composite tube packaging. A very remarkable feature of the composite tube is that its tube body material is a composite sheet, and the composite sheet is a film produced by combining a variety of different materials. material compounded together. Its production process is flexible. For example, dry compounding or extrusion compounding can be used. It can be printed and compounded into a sheet to make a tube, or it can be produced into a sheet and then printed to make a tube. It has a wide range of materials, and it can be used in terms of materials. It is polyolefin, polyamide, polyester, aluminum foil, paper, etc. The type of film material can be blown film, c...
