Disposable plastic bags must be used in supermarkets, so what are their special and excellent properties? At this stage, most of the materials of disposable plastic bags circulating in the market are composed of polyethylene, polypropylene, polyvinyl chloride, opp materials, etc. Generally, the shopping bags in supermarkets are made of high-density polyethylene (HDPE) in rolls of transparent roll bags. HDPE has good hardness and tensile strength and can bear loads, so it is the preferred material for shopping bags. Let the editor and everyone discuss the excellent properties of disposable plastic bags!

First, single-use plastic bags are light and strong. Disposable plastic bags are all plastic in nature and light in weight. The general density is one tenth of that of metal, and even the strength of reinforced plastic bags is even close to or higher than that of steel. The tensile strength of bags is also very strong, and some reinforced disposable plastic bags can even reach terrible levels.

Second, disposable plastic bags have excellent insulating properties. Almost all disposable plastic bags in China have excellent electrical insulation properties, such as small dielectric arc resistance. These excellent properties are comparable to those of ceramics.

Third, the chemical properties of disposable plastic bags are also very stable. Since single-use plastic bags are mainly made of polyethylene (PE), these plastics are corrosive to acids and alkalis.

Fourth, the anti-friction and abrasion resistance of disposable plastic bags are also excellent. Many disposable plastic bags have good anti-friction and self-lubricating properties. These shopping bags take advantage of this strong property of plastic in one piece and add some lubricity to the anti-friction plastic. Additives and fillers, which reduce the supermarket shopping bag and further improve its wear resistance.

Now do you know what are the excellent properties of disposable plastic bags? If you want to know more about plastic bags, you can check the official website of Anhui Wujiu Plastic Industry on Baidu. We will regularly update the news for you. Remember to pay attention!
