biodegradable cling film is a new type of environmentally friendly material, and its basic concept and definition are derived from the improvement and innovation of traditional plastic materials. With the increase of global environmental awareness, bio-based cling film, as a sustainable and degradable alternative, is gradually replacing traditional plastic cling film and is widely used in food packaging, household and commercial fields. Bio-based cling films will be described in detail below from a number of aspects.

1. basic concepts

Bio-based cling film is a renewable, biodegradable biomass material as the main raw material, through a specific production process and technology to make the film. This cling film has good barrier properties, stretchability and transparency, and can meet the needs of food packaging. Common bio-based materials include polylactic acid (PLA), polyhydroxyalkanoates (PHA), starch plastics, etc.

2. raw materials and manufacturing process

The raw materials of bio-based cling film mainly come from renewable resources, such as plant starch, cellulose, fatty acid and so on. These raw materials undergo biological fermentation, polymerization and other technological processes to produce bio-based polymers, and then undergo extrusion, stretching and other processes to form films. Compared with the traditional plastic manufacturing process, the manufacturing process of bio-based cling film is more environmentally friendly and reduces the dependence on fossil resources.

3. performance characteristics

1. Barrier properties: Bio-based cling film has good barrier properties, which can effectively prevent oxygen, moisture and other external factors from infringing on food.
2. Stretchability: Bio-based cling film has good stretchability and is easy to use and store.
3. Transparency: Bio-based cling film has high transparency, which is easy to observe the freshness of food.
4. Environmental protection: bio-based preservative film can be degraded and will not cause environmental pollution.

4. Application Areas

Bio-based cling film is widely used in food packaging, household and commercial fields. In terms of food packaging, bio-based cling film can be used for the preservation and storage of vegetables, fruits, meat and other foods; in the home and commercial fields, bio-based cling film can be used for kitchen cooking, tableware packaging and so on.

Comparison of 5. advantages with traditional plastics

Compared with traditional plastic cling film, bio-based cling film has the following advantages:

1. Environmental protection: bio-based preservative film can be degraded, will not cause white pollution, in line with environmental trends.
2. Sustainability: The raw materials of bio-based cling film are derived from renewable resources and will not deplete natural resources.
3. Performance advantages: Bio-based cling film has good barrier properties, stretchability and transparency, which can meet the needs of food packaging.

Current Situation and Development Trend of 6. Market

With the increase of global environmental awareness, the market of bio-based cling film is gradually expanding. More and more companies are beginning to develop and produce bio-based cling films to meet consumer demand for environmentally friendly products. In the future, the development trend of bio-based cling film will be as follows:

1. Technological innovation: With the continuous progress of production technology and technology, the performance of bio-based cling film will be improved.
2. Reduce costs: With the expansion of production scale and the reduction of raw material costs, the price of bio-based cling film will be more competitive.
3. Diversified applications: bio-based cling film will expand more application fields, such as agriculture, medical treatment and so on.

7. Conclusion

In short, bio-based cling film is an environmentally friendly and sustainable alternative with broad market prospects. With the improvement of global environmental awareness and the continuous progress of technology, bio-based cling film will be applied in more fields, bringing more convenience and environmental protection to people's lives.
