What categories are included in fully biodegradable packaging bags

Most of the soft film ceiling bag materials we use today are classified as insoluble materials. Although many Chinese companies and companies are currently working on the development and overall planning of degradable packaging bags, they have not yet replaced the large-scale production of degradable packaging that can be used for color printing packaging bags. Therefore, for color printing packaging bag companies, proper control of degradable packaging is the standard for flexible use of degradable materials and green repackaging. 1Definition and classification of degradable packaging bagsThe dissolution of plastic refers to the entire process of significantly changing its structure due to damage to natural air quality standards, lacking characteristics.The entire blending process is subject to a variety of environmental factors. Degradable packaging can be divided into photodegradable plastics, biodegradable plastics, biodegradable plastics and analytical chemical degradable plastics according to the basic principle of its dissolution. Biodegradable plastics can be divided into fully biodegradable plastics and incomplete microbial degradable plastics according to their dissolution methods. 1.photodegradable plasticPhotodegradable plastic bags refer to the cracking reaction of plastic materials under direct sunlight, which makes the raw materials lose their fracture toughness and turn into powder after a period of time under direct sunlight. Some of them can be further dissolved by microbial strains and enter the ecological environment cycle. In other words, after the molecular chain of the photodegradable plastic is destroyed by the photochemical reaction, the plastic will lose its own tensile strength and become more and more brittle. After it is naturally corroded into powder, under the action of microbial vaccine, it enters the soil stratification and enters the microbial cycle again. 2, Biodegradable plastic bagsDissolution is generally defined as: Dissolution refers to the entire process of chemical conversion of a compound based on the actual effect of hydrolysis by microorganisms or the actual effect of chemical degradation caused by microorganisms. In all processes, it is likely to be mainly manifested as chemical degradation, hydrolysis reaction, oxidative dissolution, etc.The mechanism of microbial degradation of plastics is that bacteria or ribonucleotides convert chemical fiber materials into carbon dioxide, methane gas, water, alkalized sulfides and compounds. In other words, microbial degradable plastics refer to plastics dissolved by pure natural biological strains such as germs, Aspergillus flavus (bacteria), and algae.The ideal biodegradable plastic is a chemical fiber material with high performance parameters. After being thrown away, it can be completely dissolved by the microbial strains in the pure natural environment. After all, it becomes the organic chemical composition of the natural carbon cycle according to the actual effect of inorganic compounds. part. In other words, it dissolves into the first-order molecular formula and can be further dissolved or digested and absorbed by pure natural pathogenic bacteria.The basic concepts of dissolution can be divided into two categories: one is biophysical dissolution. When microbial species attack and erode polymer materials, the increase in the dilution of microorganisms promotes the hydrolysis reaction, hydrolysis or protonation of the polymer components, and converts them into oligomer fragments. The chemical formula of polymers is not easy to modify. It is the whole process of dissolving the polymer under the actual effect of biophysics. The second type is microbial chemical degradation. Due to the immediate practical effect of microbial strains or enzymes, the high polymer is dissolved or oxidized into small molecular water, until it is finally converted into carbon dioxide and water. Such dissolution methods are classified as microbial chemical degradation methods.

  1. Having read this I believed it was really enlightening. I appreciate you finding the time and effort to put this article together. I once again find myself personally spending way too much time both reading and commenting. But so what, it was still worthwhile!
