Teach you to sort out the types of shopping bags
Non-woven shopping bag
Non-woven shopping bags are non-woven fabrics made of plastic. Many people think that cloth is a natural material, which is actually a misunderstanding. Commonly used non-woven raw materials are polypropylene (referred to as PP, commonly known as polypropylene) or polyethylene terephthalate (referred to as PET, commonly known as polyester), especially PP is the same as PE used in plastic shopping bags. The five general-purpose plastic varieties belong to plastics that cannot be degraded in 50 years. For example, ordinary non-woven shopping bags, which we all call environmentally-friendly shopping bags, are made of polypropylene fiber by special process. In essence, polypropylene (PP) is a typical type of plastic, which is also a plastic bag, so it is environmentally friendly. Like ordinary plastic shopping bags, they are not completely degraded.
In terms of specific cost performance, the non-woven fabric bag under the same conditions is not as strong as a plastic bag, and is not waterproof, and its price is several times higher than that of a plastic bag. What needs to be mentioned is that the non-woven shopping bags made of more than two kinds of materials are more difficult to recycle and reuse than ordinary plastic shopping bags.
Paper shopping bag
Everyone knows that the strength and water resistance of paper are not good. Many water-based products such as seafood cannot be packaged, and heavier metal products are also difficult to bear. Even if everyone changed to a paper bag, how did the paper come from? First of all, the raw materials for making paper are mainly wood, and the world's forest resources are extremely scarce. This is the biggest waste of environmental resources. Secondly, the process of making paper will produce a lot of water pollution. Paper mills across the country, such as street mice, are beaten everywhere. Therefore, the large amount of paper bags is the biggest waste of environmental resources and the greatest pollution to the environment.
Cotton and linen shopping bag
Cotton and linen shopping bags are stronger than paper bags and can be recycled many times, but the water resistance is not good. The advantage of cotton and linen shopping bags is that they can be recycled, but what if the bags are dirty? Washing with water is the most common method, but washing with water is a waste of water. Phosphorus-containing washing powder contaminates the soil, and ordinary washing does not kill bacteria.
