Anti-bacterial plastic bag and production method thereof

Abstract

The invention relates to the technical field of product package, in particular to an anti-bacterial plastic bag and a production method thereof. An anti-bacterial protection layer can be formed to guarantee that the plastic bag is clean and free from pollution. The plastic bag comprises a plastic bag body which comprises the following raw materials in parts by weight: 5-10 parts of linear low-density polyethylene with the melt index of 1.7-2.3 g / 10 min, 5-10 parts of metallocene polyethylene with the melt index of 0.3 g / 10 min, 25-35 parts of high-density polyethylene with the melt index of 0.29-0.33 g / 10 min, and 1-5 parts of anti-bacterial color masterbatch. The production method comprises the following steps: (1) weighing the raw materials according to the weight ratio; (2) placing the raw materials in a plastic refining machine, and heating for 16-20 min at the temperature of 130-160 DEG C, so as to obtain a plasticized hot material; (3) conveying the plasticized hot material to an extruder through a screw conveyor, wherein the temperature of the rotating die head of the extruder for central feeding is 140-150 DEG C, and performing extrusion blowing for molding, and automatically air-cooling under over temperature, so as to obtain a plastic film; (4), tailoring, folding the plastic film and sealing edges of the plastic film, so as to obtain the plastic bag.

Description

technical field [0001] The invention relates to the technical field of article packaging, in particular to an antibacterial plastic bag and a production method thereof. Background technique [0002] At present, plastic bags have entered people's daily life. They are convenient and practical. The existing common plastic bags are simply processed. During use, due to the built-in items and the external environment, it is easy to breed bacteria and be polluted. While plastic bags are often used to store food, etc., food, etc. are subsequently contaminated. Contents of the invention [0003] In order to solve the above problems, the present invention provides an antibacterial plastic bag, which can form an antibacterial protective layer to ensure that the plastic bag is clean and free from pollution. [0004] Its technical solution is as follows: an antibacterial plastic bag, characterized in that it includes a plastic bag body, and the plastic bag body has the following raw m...
