Promote the use of degradable packaging bags for fresh products. Establish a centralized buying and selling system for shopping bags in the bazaar. Promote the use of bio-based products such as straw-coated lunch boxes that meet performance and food safety requirements, and alternative products such as biodegradable plastic bags in the field of food delivery.
· Cultivate and optimize new business forms and new models
Strengthen corporate green management responsibilities and promote green supply chain. E-commerce, food delivery and other platform companies should strengthen the management of merchants settled in, formulate implementation plans for reducing the amount of disposable plastic products, and release the implementation status to the society.
Focusing on chain supermarkets, large-scale bazaars, logistics warehousing, e-commerce express delivery, etc., promote enterprises to actively promote recyclable and foldable packaging products and logistics distribution equipment through equipment leasing, financial leasing, and other methods.
5. Improve the support and guarantee system
· Establish and improve regulations and standards.
Update and release the banned list of plastic products in due course.
Formulate green design guidelines for plastic products.
Formulate and revise standard labels for degradable materials and products.
Establish and improve the green management and evaluation standards of enterprises in emerging fields such as e-commerce, express delivery, and food delivery.
Research on the classification and evaluation of packaging suitability of commodities with prominent packaging problems, and propose differentiated management measures.
Incorporate the management and control requirements of disposable plastic products into the evaluation and rating standards of tourist attractions, star-rated hotels and hotels
Explore the establishment of a production and sales information disclosure system for plastic raw materials and finished products.
Explore the implementation of corporate legal persons’ promises and punishments for dishonesty, and include illegal production, sales, and use of plastic products in the record of dishonesty.
· Improve relevant support policies
Implement relevant fiscal and taxation policies and increase government procurement of green products that meet the standards. Carry out pilot demonstrations such as the construction of a new green supply chain, the promotion of new products and new models, and the recycling of waste agricultural film.
According to relevant policies, we also launch corresponding alternative products
[Starch-based fully degradable plastic bag/starch bio-based fully degradable plastic bag]
Material content:
1. Ingredients: starch bio-based fully biodegradable resin, ingredients PBAT+PLA+ST
2. Ingredient content: PBAT content 60-70%, PLA content 5-15%, ST content 15-35%;
PBAT:
① Thermoplastic biodegradable plastic is a copolymer of butylene adipate and butylene terephthalate;
② Features:
· Good ductility and elongation at break;
· Better heat resistance and impact performance;
· Excellent biodegradability, which is very active in the research of biodegradable plastics and one of the best degradable materials for market applications;
PLA:
① Polylactic acid, a new type of biodegradable material, is made from starch raw materials extracted from renewable plant resources (such as corn).
② Process: Starch raw materials are saccharified to obtain glucose, which is then fermented by glucose and certain strains to produce high-purity lactic acid, and then a certain molecular weight polylactic acid is synthesized by chemical synthesis. Process: starch→glucose→lactic acid→polylactic acid
③ Features:
· Good biodegradability, after use, it can be completely degraded by microorganisms in nature, and eventually carbon dioxide and water are generated without polluting the environment. This is very beneficial to environmental protection and is recognized as an environmentally friendly material.
· Good mechanical and physical properties, suitable for blow molding, thermoplastic and other processing methods, easy to process, and widely used. Applications related to us include: packaged food, fast food lunch boxes, non-woven fabrics, etc.
· Good gloss and transparency, comparable to films made of polystyrene, which cannot be provided by other biodegradable products.
· Polylactic acid is the only biodegradable plastic with excellent antibacterial and antifungal properties.
· During incineration, its combustion calorific value is the same as that of incineration paper, which is half that of incineration of traditional plastics (such as polyethylene), and incineration of polylactic acid will never release toxic gases such as nitrides and sulfides. The human body also contains lactic acid in the form of monomer, which shows the safety of this decomposable product.
5. ST: starch
This product has no distinction between high pressure membrane and low pressure membrane
About degradation:
1. Degradation conditions and principles: contact with microorganisms;
2. Degradable: because this plastic has undergone process modification;
3. Under the conditions of industrial composting, it can be completely converted into carbon dioxide, water and macromolecular inorganic substances within 180 days without leaving any substances harmful to the soil.
4. Under ordinary landfill conditions, shopping bags can also be completely degraded within 1-2 years (the specific time depends on the thickness of the bag).
5. Products and raw materials have been tested by international and domestic authoritative organizations and have obtained testing certification.
Notes on the use of biodegradable plastic shopping bags
1. Regarding the performance of shopping bags, fully biodegradable materials must ensure 100% biodegradability
