When it comes to plastic bags, everyone should be familiar with it. After all, when you go shopping, you will use plastic bags to store things, and you also have some bags in your home. When you move or store things, you will put a layer of plastic bags to prevent dust from falling. , It can be said that it has brought a lot of convenience to the lives of the people, but with the development of the times, the requirements for plastic bags are getting higher and higher, so the products are also being updated, and everyone may still understand this in their previous memories. Next, today I will take you to learn about new knowledge about plastic bags.

1. The original plastic bag product

In the past, plastic bags were made of polyvinyl chloride, polypropylene, high-density low-density polyethylene, etc., but polyvinyl chloride can be seen as toxic from the word chlorine, and the way to distinguish this bag is that it is rough to the touch, and When ignited, the flame is green because of the chlorine element in it. Plastic products made of this kind of material are what everyone calls white pollution. People used to throw away such plastic bags casually before, causing pollution. Even if they have been in the soil for decades, they will remain the same. So the previous white pollution of the ocean caused a large number of tiny white particles to mix in the seawater, according to the latest research released by the World Health Organization.

2. Now plastic bag products

With the development of the times, the requirements for plastic bags are also becoming higher, and there are now environmentally friendly plastic bags, which are also called degradable plastic bags. In short, they can be decomposed by nature. The raw materials of the products are fibers. Gluten, starch, ethanol, etc., are all degradable components. Just like in the newspapers published in 2017, there was an article about cellulose plastic bags, which was Lithuania’s Kolas University of Science and Technology. This team not only improved the safety of the product on the basis of the degradable cellulose in a sealed bag.

With the advent of the era of environmental protection, I believe that in the near future, PVC plastic bag materials have become a thing of the past!
