The development history of plastic bags:
In the 1850s, Parkes looked at different methods of processing collodion. One day, he tried to mix collodion with camphor. To his surprise, the mixture produced a bendable hard material. Parkes called this substance “Paksim”, which was the earliest plastic. In 1909, Baekeland in the United States synthesized phenolic plastic for the first time. In the 1930s, nylon came out, and it was called “a fiber made from coal, air and water, thinner than spider silk, harder than steel, and better than silk.” Their appearance laid the foundation for the invention and production of various plastics.
Advantages of plastic bags:
Water-soluble speed can be designed and selected, completely dissolved in water, non-toxic and non-polluting; high softness, good touch; good oil and solvent resistance, heat-sealable and printable; low air permeability, good gas barrier; plastics can be added Female buckle or self-adhesive plastic bag; can be degraded by water, air, sunlight and biodegradability. Usually it can be decomposed into harmless substances in about a month.
