Problems solved by technology

[0002] Polyethylene (PE) has good chemical stability, puncture resistance, impact and environmental friendliness, etc. It is often used in film or blown film packaging in food, beverage, cosmetics, electronics, toys, printing and other industries, but polyethylene The smoothness is relatively poor, and the antistatic effect is not good
At the same time, with the improvement of people's living standards, the demand for antibacterial polyethylene products is also increasing. Adding an appropriate amount of antibacterial agent can endow polyethylene products with a certain antibacterial and bactericidal ability, but the disadvantage is that the antibacterial performance is poor in durability, and it may also lead to During the production process, due to the heat reaction, the product turns yellow and discolored, etc.
