Plastic bag factories, especially in the production and use of PE plastic bags, often have white powder, which causes great troubles to some customers who are packaging clothing. After a lot of experiments and research conducted by our company, this problem has been successfully solved. The specific operation methods are introduced as follows for reference by colleagues.1. Use of raw materials: Imported materials such as 150Y\/0474 must be used as the main materials with better quality; 2. The ratio of raw materials: Use the ratio of 2 packs of main ingredient and 3 packs of tensile material, and stir well; 3. Add accessories: According to the experimental results, 7042 granules produced in Guangzhou can effectively adhere to the powder in the PE plastic bag production process. When the film is blown, it is added at a ratio of about 2%, which can effectively prevent the appearance of the powder in the PE plastic bag. Fine-tune the situation; 4. Matters needing attention: Be sure to control the amount of addition. If it is too small, it will not work. If it is added too much, the plastic bag and the bone bag will not open, and it will seriously affect the printing operation and cause wrinkles.
