Biodegradable barrier film is a kind of film made of natural or synthetic polymer materials, which is characterized by its ability to be decomposed into harmless small molecules under specific conditions (e.g., in soil, in water, or through microbial action). This kind of film not only has the functionality of traditional plastic film, but also can effectively reduce the environmental pollution problem, which is an important direction in the current research field of environmental protection materials.
Features
- environmentally friendly: compared with ordinary plastics, biodegradable barrier film can be naturally decomposed after the completion of its service life, and will not cause long-term accumulation of environmental pollution.
- good physical properties: many types of biodegradable films have good mechanical strength and flexibility, which can meet the needs of different application scenarios.
- Controllable degradation rate: Adjusting the formula according to the actual needs can control the degradation rate of the membrane material, so as to adapt it to different usage environments and deadlines.
- Wide range of application potential: from food packaging to agricultural cover to medical and health care and other fields have a broad application prospect.
Applications
- food packaging: using biodegradable barrier films as food preservation bags or container liners can not only maintain food freshness but also reduce the impact of waste on the environment.
- Agricultural field: used for mulching, not only can increase crop yield, but also can be directly turned into the soil as fertilizer after use, avoiding the problem of recycling.
- Pharmaceutical industry: made into a part of the drug slow-release system to realize the timed and quantitative release of drugs; or as a part of disposable medical devices to reduce the amount of hospital waste.
- Daily necessities: develop biodegradable materials that can be used to make daily consumables such as shopping bags and garbage bags, replacing traditional non-biodegradable plastic products.
- Environmental protection: applied in the process of sewage treatment, to help separate pollutants and at the same time be easily decomposed by microorganisms in the water body.
