Fully biodegradable

At the beginning of the year, the General Administration of Quality Supervision, Inspection and Quarantine and the National Standards Committee approved the release of cosmetics, express packaging bags, fireworks and firecrackers, etc.291national standard. Among them, the new standard for express packaging requires that express packaging bags should be made of fully biodegradable materials..Click to learn about National Express Garbage Amazing! Biodegradable packaging bags provide degradation solutionsThe newly revised national standard series of “Express Packaging Products” has supplemented and improved the relevant content of the original standards according to the requirements of reduction, greening and recyclability. The new standard reduces the quantitative requirements for express envelope paper, air-cushion film express packaging bags, and PLA stic woven cloth express packaging bags. In addition, it is also required that express packaging bags should be made of biodegradable materials, and the limit requirements for heavy metals and specific substances have been increased.According to statistics, the national2017Including e-commerce and express delivery companies (used accounted for60%), using a total of120Billion to130billion express packaging bags. The degradation cycle of traditional materials is200More than a year, it will cause serious pollution to the environment, and fully biodegradable PLA stics can greatly accelerate the degradation rate and reduce the pressure on environmental protection.Biodegradable materials refer to a type of PLA stic that is degraded by the action of microorganisms such as bacteria, mold (fungi) and algae that exist in nature. According to the different biodegradation process, it is divided into two categories: completely biodegradable PLA stics and biodegradable PLA stics. Fully biodegradable PLA stics are chemically synthesized using aliphatic polyester, polyvinyl alcohol (PVA) and polyethylene glycol production are easily degraded. Biodegradable PLA stics are incompletely biodegradable PLA stics. Biodegradable substances are mixed into olefin general-purpose PLA stics to make the material lose its mechanical properties and shape, and the same effect as biodegradable properties can be produced through composting. Because of this type of PLA stic The cost is low, and this method has been adopted at home and abroad.
