Because people pay more and more attention to the protection of the environment.
Bags: non-woven paper and ordinary compared cloth has the advantages of short manufacturing process and do not produce wastewater, waste gas and waste; in the use of the process for folding, easy to carry, can be repeated washing, use heating or burning; because of polypropylene produced by decomposition of carbon dioxide and water, will not harm the human body. So the recovery time is also environmentally friendly. Compared with non-woven bags and plastic bags, the price is high, but it has the advantages of tensile, tear resistance, anti bursting, high strength, high elongation coefficient and high mechanical strength, and has good air permeability. It belongs to the advantages of raw liquid dyeing and non fading. On the thickness, the non-woven fabric is a few times the plastic bag; in the manufacturing process, the plastic bag uses the blow molding process, and the non-woven fabric is used to spray the plastic process. All this makes the nonwoven bag a lot stronger than the plastic bag. At the same time, the polyester component in the non-woven fabric makes it easy to clean and is more useful for repeated use. Compared with various factors, nonwoven bag is more practical than plastic bag and paper bag.
Paper bags: the mass production of paper bags will lead to deforestation, which is actually destroying the environment, not conducive to environmental protection, which is actually a misunderstanding. Recycled paper bags are very short and cannot be weighed too much. If we want to increase the negative weight, we must make plastic or glue treatment. In this process, plastic is still needed. If we consider the scarcity of tree resources and other factors, if we use paper bags to replace plastic bags, we will have to cut down large areas of trees, which will result in ecological damage. In fact, paper bags are not very environmentally friendly.
Plastic bags: not easy to degrade, buried in the underground for a long time not rotten, to bring burdens to the mother of the earth.
