Biodegradable sheet production line manufacturers believe that biodegradable materials refer to materials that can be degraded through the interaction between natural microorganisms such as bacteria, fungi, and algae. This substance can be completely decomposed by environmental microorganisms, and after decomposition, it becomes carbon dioxide and water or methane and water. The degradation products of biodegradable packaging materials can participate in the natural carbon nitrogen cycle. Carbon and nitrogen elements can not only form the basic skeleton of an organism, but also achieve its metabolism through its own biochemical reactions. Therefore, biodegradable plastic packaging materials are environmentally friendly.

The manufacturer of degradable sheet production line believes that photodegradation plastic packaging materials refer to materials that will automatically degrade under the action of light. The reaction mechanism is that plastic absorbs ultraviolet rays from sunlight, leading to a decrease in bond energy, long chain breakage of polymers, and the transformation of large molecules into small ones, which continue to undergo oxidation reactions. Free radicals will break chains, and small molecular fragments will be completely oxidized by air. Photodegradation plastics can be divided into copolymerization and addition molding.
Manufacturers of degradable sheet production lines believe that copolymer plastics are a type of plastic formed by the copolymerization of monomers such as carbon monoxide or other olefins. The carbonyl chromophores and some weak bonds on the polymer chain are more unstable under light conditions, so as to achieve photodegradation. Additive type refers to adding photosensitizers such as benzophenone to ordinary plastics to absorb light at a wavelength of 300nm, promote intermolecular dehydrogenation, continuously reduce molecular weight, and achieve complete degradation. The necessary condition for photodegradation plastics to be degraded is sufficient light, that is, ultraviolet ray. When there is insufficient light or ultraviolet radiation, the material is difficult to degrade and the reaction conditions are harsh.
Manufacturers of biodegradable sheet production lines believe that with the development of society, medical treatment has become a hot topic. The treatment of medical waste is receiving increasing attention. It is filled with absorbent substances, and when medical waste is thrown into water after use, it will completely dissolve in the water. Ordinary medical gloves are treated this way.
Manufacturers of degradable sheet production lines believe that the main method for preparing flame retardant polymer materials in China is to use physical and mechanical methods, and add flame retardants to ensure the flame retardancy of polymer materials. Although this method used domestically is very convenient, there are still many problems in the actual preparation process, such as the large amount of flame retardants used. Moreover, adding flame retardants to polymer materials can directly affect the mechanical and physicochemical properties of the matrix polymer, especially its processing, electrical, and mechanical properties. At the same time, the poor stability of flame retardants in materials leads to their easy loss during use, which not only pollutes the environment but also causes serious resource waste. In addition, bromine and chlorine flame retardants are widely used due to their high flame retardancy. However, relevant studies have fully shown that brominated flame retardants generate a large amount of toxic gases during the flame retardant process, which not only poses an extremely serious threat to the environment and people's safety, but also greatly reduces the UV resistance of flame retardant matrix materials, thus prompting people to pay more and more attention to the problems caused by this.
