At present, the raw materials of flexible packaging films we use are basically non-degradable materials. Although many countries and enterprises are currently working on the development of degradable materials, there is currently no substitute for large-scale production of degradable materials that can be used in flexible packaging. As the country pays more and more attention to environmental protection, many provinces and cities have successively issued regulations to limit plastics and even "ban plastics in some fields. Therefore, for flexible packaging companies, to correctly understand degradable materials is to make good use of degradable materials." , The premise of realizing green and sustainable packaging.
According to relevant definitions, bio-based plastics refer to plastics produced under the action of microorganisms based on natural substances such as starch. Biomass for bio-based plastic synthesis can be derived from corn, sugar cane or cellulose, etc. And biodegradable plastics refer to under natural conditions (such as soil, sand, seawater, etc.), or under specific conditions (such as composting conditions, anaerobic digestion conditions or aqueous culture liquids, etc.) , fungi and algae, etc.) cause degradation and eventually complete degradation of plastics into carbon dioxide, water, methane, mineralized inorganic salts and new biomass. Bio-based plastics are defined and classified based on the source of material composition; while degradable plastics are classified from the perspective of the material's end-of-life. In other words, 100% bio-based plastics may not be biodegradable, while some traditional petroleum-based plastics can be biodegradable, such as butylene terephthalate (PBAT) and polycaprolactone (PCL) .
At present, for degradable packaging, customers are more concerned about whether it can meet the performance requirements of the packaging; for flexible packaging manufacturers, it is necessary to consider which fields can be used and how much can be used, because degradable materials are in the short term. Conditionally degradable. At present, degradable materials have not yet formed a mature supply chain. Therefore, packaging in the next few years may be recyclable packaging and degradable packaging go hand in hand.
