Which PE plastic bags are specially made

PE plastic bags refer to bags made of polyethylene (Polyethylene) materials. Polyethylene is a common plastic material with high toughness, wear resistance and plasticity. PE plastic bags are widely used in daily life, including shopping bags, food packaging bags, garbage bags and so on.

The production process of PE plastic bags is relatively simple, mainly including melt extrusion, bag forming, cutting and other steps. First, polyethylene particles are melted into a liquid state by heating, and then the liquid polyethylene is pressed into a continuous plastic film by an extruder. After this film is cooled, it can be cut into plastic bags of a specific size by a cutting machine. One of the advantages of PE plastic bags is that they are cheap. Because polyethylene is a cheap plastic raw material, the production cost of PE plastic bags is low, resulting in a relatively low price. This makes PE plastic bags a widely used packaging material. Another advantage is the toughness and wear resistance of PE plastic bags. Polyethylene material has high toughness, is not easy to break, and can withstand a certain degree of tension. This makes the PE plastic bag not easy to break during use, can be reused, and reduces waste of resources. In addition, PE plastic bags also have good wear resistance and are not easily damaged by friction, so they have a long service life. PE plastic bags also have good waterproof performance. Due to the high density and low permeability of polyethylene material, PE plastic bags can effectively prevent the penetration of moisture and moisture. This makes it the preferred material for food packaging, such as fruits and vegetables, meat, snacks and other packaging often use PE plastic bags to maintain the freshness and quality of food. However, PE plastic bags also have some disadvantages. First of all, PE plastic bags are disposable supplies, can not be recycled. Because polyethylene is a plastic material that is difficult to degrade, it will cause some pollution to the environment. Secondly, PE plastic bags need to use certain chemicals in the production process, which will produce some harmful gases and waste water. This may pose a threat to the environment and human health. In recent years, with the improvement of people's awareness of environmental protection, the use and recycling of plastic bags has been widely concerned. Some countries and regions have begun to gradually restrict the use of plastic bags and promote alternatives such as environmentally friendly bags. In addition, the classification and recycling of PE plastic bags to further reduce their pollution to the environment is also an effective solution. In short, PE plastic bags, as a common packaging material, play an important role in our lives. It is cheap, good toughness, waterproof, can meet our various needs. However, it also has some problems, such as difficulty in degradation and pollution to the environment. In the future development, we need to actively look for alternative environmentally friendly materials, or implement a recycling system to reduce the negative impact on the environment.
