Embodiment

[0012] A preparation method for a bacteria-resistant packaging bag, comprising the following steps:

[0013] Step 1. Put 70-80 parts of low-density polyvinyl chloride particles and 10-15 parts of vinylidene chloride resin particles into a high-temperature mixing tank for high-temperature mixing, heating at 250-300°C, and stirring for 30-60 minutes;

[0014] Step 2. Slowly inject 5-10 parts of plasticizer and 2-5 parts of stabilizer into the above mixture, and continue stirring for 15-20 minutes;

[0015] Step 3. After lowering the temperature to 200-250°C, slowly add 3-5 parts of CKJ-A nanocomposite antibacterial agent, 10-12 parts of straw fiber, and continue stirring for 10-15 minutes;

[0016] Step 4, the above mixture is transferred to a film blowing machine, and the mixture is made into a plastic film;

[0017] Step 5, transfer the above-mentioned plastic film to the bag making machine, and make the plastic film into a packaging bag.

Abstract

The invention discloses a preparation method of an antibacterial packaging bag. The preparation method comprises the following steps: (I) putting 70-80 parts of low-density polyvinyl chloride particles and 10-15 parts of vinylidene chloride resin particles in a high-temperature mixing tank, and mixing at a high temperature, heating to 250-300 DEG C, and stirring for 30-60 min; (II) slowly injecting 5-10 parts of a plasticizer and 2-5 parts of a stabilizer into the mixture, and continuously stirring for 15-20 min; (III) reducing the temperature to 200-250 DEG C, slowly adding 3-5 parts of CKJ-Atype nano composite antibacterial agent and 10-12 parts of straw fiber, and continuously stirring for 10-15 min; (IV) transferring the mixture into a film blowing machine, and making the mixture intoa plastic film; (V) transferring the plastic film into a bag making machine, and making the plastic film into a packaging bag. The antibacterial packaging bag provided by the invention has good antibacterial property.

Description

technical field [0001] The invention relates to a preparation method of a bacteria-resistant packaging bag. Background technique [0002] Existing plastic packaging bags themselves do not have antibacterial performance, and the antibacterial performance of packaging bags needs to be developed. Contents of the invention [0003] The object of the present invention is to provide a bacteria-resistant packaging bag to solve the above problems. In order to achieve the above object, the technical solution of the present invention is to design a kind of preparation method of antibacterial packaging bag, comprising the following steps: [0004] Step 1. Put 70-80 parts of low-density polyvinyl chloride particles and 10-15 parts of vinylidene chloride resin particles into a high-temperature mixing tank for high-temperature mixing, heating at 250-300°C, and stirring for 30-60 minutes; [0005] Step 2. Slowly inject 5-10 parts of plasticizer and 2-5 parts of stabilizer into the abov...
