Biodegradable shrink film is a film material made from natural or synthetic polymers, whose main characteristic is that they can be decomposed into environmentally friendly substances such as carbon dioxide, water and biomass under specific conditions (e.g. microbial action). This type of material has a wide range of applications in the packaging industry, especially for product packaging that has high requirements for environmental protection.
Features
- Environmental friendliness: Compared with traditional plastics, biodegradable shrink film can reduce environmental pollution problems because it can decompose faster in the natural environment.
- Functionality: In addition to good mechanical properties, this film has excellent transparency, flexibility and heat resistance, suitable for a variety of packaging needs.
- safety: when used for food packaging, it must be ensured that the raw materials used are harmless to humans and do not release harmful substances to contaminate food.
- Versatility: Depending on the application, formulations can be adapted to change the color, thickness and other physicochemical properties of the film.
Applications
- Food packaging: due to its safety and environmental characteristics, it is very suitable for wrapping fresh fruits and vegetables, meat products and other perishable foods.
- Daily necessities packaging: can be used as an external protective layer for non-food commodities such as disposable tableware and sanitary products.
- Agricultural field: used as mulch to cover crops, which not only helps to maintain soil moisture but also prevents weeds from growing; it can also be left directly in the field to degrade naturally after harvest.
- Industrial Packaging: It can be used for the transportation packaging of electronic products, toys and other light industrial products, which can play the role of dustproof and waterproof as well as facilitate the recycling process.
