Abstract

The invention discloses a preparation method of the plastic packaging bag. The plastic packaging bag is prepared from the following components in parts by weight: 85-100 parts of linear low-density polyethylene particles, 25-30 parts of ethylene-vinyl acetate resin particles, 15-16 parts of calcium carbonate powder, 12-15 parts of bamboo fibers, 8-10 parts of composite antibacterial agent, 8-10 parts of phthalic acid ester and 1-1.5 parts of nanometer Au36(SCH3)24 clusters. The preparation method comprises the following steps: (1) raw material drying; (2) melting; (3) modification; (4) film blowing; (5) bag preparation; (6) edge sealing; and (7) stamping. According to the preparation method, linear low-density polyethylene and ethylene-vinyl acetate resin are adopted as base materials, andthe composite antibacterial agent is added, so that the plastic packaging bag has good bacterium inhibiting performance; the bamboo fibers and the calcium carbonate powder are added in a formula provided by the invention, so that the tensile strength and toughness of the plastic packaging bag are improved; and the preparation method disclosed by the invention is simple, good in practicability andgood in antibacterial effect.

Description

technical field [0001] The invention belongs to the technical field of plastic packaging bag preparation, and in particular relates to a method for preparing a plastic packaging bag. Background technique [0002] Plastic shopping bags are a necessity in daily life. As we all know, consumers and shopping malls have formed a rigid demand for plastic packaging bags, and this consumption has become a habit, and plastic packaging bags have been integrated into everyone's life. In daily life, plastic packaging bags are increasingly becoming the first choice for packaging products due to their light weight and ease of use. In developing countries, due to the process of commercialization, the number of shopping malls has increased steadily, which has led to the further prosperity of the plastic packaging bag industry, and the two show a high degree of correlation. The global plastic packaging bag industry generally shows a steady growth trend, especially the total demand for plasti...
