What is biodegradable plastic bags

Degradable plastic refers to the plastic that is easier to degrade in the natural environment after adding a certain amount of additives (such as starch, modified starch or other cellulose, photosensitizers, biodegraders, etc.) in the production process to make it less stable.

Biodegradable Plastics Testing and Certification

Biodegradable plastics, also known as biodegradable plastics, are plastics that are degraded by microorganisms in nature (soil, sand, etc.) or under specific conditions (compost, anaerobic digestion, aqueous culture solution, etc.) and eventually degrade completely into carbon dioxide, water and mineralized inorganic salts of the elements they contain, as well as new biomass.

What are the categories of biodegradable plastics?

China's National Development and Reform Commission officially issued the "Opinions on Further Strengthening Plastic Pollution Control" on January 19, 2020, the Soil Law introduced in 2019 clearly encourages the use of biodegradable agricultural films, and the 2019 Executive Meeting adopted the Draft Law on Prevention and Control of Solid Waste Pollution in the Environment (Revised Draft), which clearly encourages the research and development and production of environmentally degradable film coverings and commodity packaging.

What are the biodegradation testing standards?

Biodegradation: The material is continuously discharged from the body during the process of tissue growth in the organism through dissolution, enzymatic digestion, cellular phagocytosis, etc. The repaired tissue completely replaces the implanted material, and the material does not have a residual nature in the body.

Dissecting biodegradable plastic standards

The PAS 9017 standard covers polyolefins, a class of thermoplastics that includes polyethylene and polypropylene, which constitute half of all plastic pollution in the environment.

Biodegradable plastic, a new way out of environmental protection

The end of the year shopping spree is in full swing, "campaign" major online platform "buy buy buy" at the same time, a variety of express parcels, plastic packaging and other waste increases the problem also came. According to data released by the global environmental organization Greenpeace, if effective measures are not implemented to control, according to the current development trend of express delivery, China's consumption of various types of express packaging materials will reach 41,270,500 tons in 2025, bringing a huge resource burden and environmental pressure. Can these packaging materials be replaced with more environmentally friendly materials? Many people will look to biodegradable plastic. Will this new type of plastic be the way forward for the environment? In this edition of Curiosity Lab, we invite Associate Professor Shen Yucai from the School of Materials Science and Engineering of Nanjing University of Technology to explain.

Environmental policy compulsory plastic ban - in Henan

Henan Provincial Development and Reform Commission issued a document: Since January 1, 2022, the province's cities at the county level and above in urban built-up areas such as shopping malls, supermarkets, pharmacies, bookstores and other places and catering packaged take-out services and various exhibition activities are prohibited from providing with non-degradable plastic bags (excluding pre-packaged bags, even rolled bags, fresh bags), catering services are prohibited from providing disposable plastic tableware; the province's tourism star hotels and other places shall not Active provision of disposable plastic supplies, can be set up through the self-service purchase machine, provide refill type detergent and other related services.

What is the difference between compostable, biodegradable, and bioplastic?

China's packaging industry has entered a critical development period of upgrading and quality and deep transformation, to achieve the "sustainable development" of the packaging industry, there are still many common problems and constraints bottlenecks. The study of the latest trends and drivers in the global packaging field has important implications for the future direction of China's packaging industry.

The end of 2025 postal delivery network banned non-biodegradable plastic bags

Recently, China's State Postal Bureau said at a routine press conference: to ensure that by the end of 2025, a nationwide ban on the use of non-degradable plastic packaging bags, plastic tape, disposable plastic woven bags, etc. in postal delivery outlets. Achieving a green consensus in the industry is a gradual process. At present, each express company has also made many efforts in greening express packaging. In the next step, the State Post Bureau will steadily promote the pilot work, actively cultivate the scale of courier packaging recycling application mode, and accelerate the green transformation of courier packaging. In addition, low-carbon logistics is an inevitable trend for future development, and improving carbon efficiency through technological means will become the main choice of logistics enterprises.

What are the advantages of biodegradable plastic bags?

The advantages of biodegradable plastic bags: biodegradable materials are mainly made of PLA and PBAT blended together, PLA and PBAT blended together to improve the toughness of PLA, showing the complementarity of the two.
