Problems solved by technology

[0002] At present, due to its good storage and portability, plastic packaging bags can quickly and efficiently store and transport products. They are more and more widely used in our daily production and life. Plastic films are now common daily necessities. Plastic film has the advantages of good transparency, good moisture resistance, excellent heat resistance, convenient use, and low price, and is widely used in various industries. At present, the plastic film on the market is mainly polyethylene plastic film, but some products There will be problems such as wrinkles, poor transparency, uneven thickness, and many fish eyes in the film bubble
Some plastic films are used for food packaging, but they contain toxic plasticizers, which affect the quality of food and endanger human health
At the same time, due to the poor antibacterial properties of traditional packaging bags, bacteria are more likely to grow when packaging various food products
