Plastic bag, PE waterproof bag--What is the difference between PE bag and nylon bag?

Today the author will tell you about plastic bags, PE waterproof bags-the difference between PE bags and nylon bags 　　 polyethylene, referred to as PE. It is a high molecular organic compound formed by addition polymerization of ethylene. Polyethylene is recognized as the best material in contact with food in the world. It is non-toxic, tasteless and odorless, and meets food packaging hygiene standards. Polyethylene film, light and transparent, has the properties of moisture resistance, oxygen resistance, acid resistance, alkali resistance, general air tightness, and excellent heat sealability. It is the most important and most used material for plastic packaging printing. Pe is divided into high density and low density. Generally used in supermarkets (vest bags) are high-density PE plastic bags. Most of the handbags commonly used in daily life are made of low-density PE, such as handbags used in clothing stores.　　 After introducing PE, let's talk about nylon. Nylon is a synthetic fiber material, the main component is resin. Because nylon has good comprehensive properties, including mechanical properties, heat resistance, abrasion resistance, etc., nylon bags not only have the advantages of waterproof, light and tough, but also can be washed and reused. From the perspective of environmental protection, compared to ordinary plastic bags, nylon bags are more easily degraded and are a very environmentally friendly material.　　Plastic bag is a general term, as long as it is made of synthetic resin material, it is called plastic bag. Both PE bags and nylon bags are plastic bags, with different materials. PE bags are divided into high density and low density. High-density ones are tougher, have high transparency, feel stiff, and are relatively expensive. Generally, the plastic bags given by supermarkets are high-density PE bags. Low-density PE bags are the most common soft-to-touch bags sold in the general market. They are of inferior quality, poor transparency, and cheap. Nylon bags refer to plastic bags made of various polyamides, which vary depending on the specific amide material. But in general, the appearance is good in texture, thick, and silky and smooth to the touch. Generally used for high-end clothing, jewelry and other commodities, the price is relatively high.　　 Label: PE waterproof bag
