PLA Film For Food

PLA Film for Food

PLA film, or Polylactic Acid Film, is a bio-based and biodegradable plastic film made from renewable resources (such as corn starch, sugar cane, etc.). Here are some of the main features of PLA film:

1. **Environmental protection**: PLA film is made from renewable resources, which reduces dependence on fossil fuels compared to traditional petroleum-based plastics, and is biodegradable under appropriate conditions.

2. **Biodegradability**: Under industrial composting conditions, PLA film can be decomposed into water, carbon dioxide and biomass by microorganisms, and will not cause long-term pollution to the environment.

3. **High transparency**: PLA film has good transparency, similar to traditional plastic film, and is suitable for packaging applications that require high transparency.

4. **Good printing performance**: The surface of PLA film is suitable for printing and can be used in various packaging designs.

5. **Mechanical properties**: PLA film has certain strength and toughness, but its mechanical properties are generally not as good as traditional petroleum-based plastics such as polyethylene (PE) or polypropylene (PP).

6. **Thermal performance**: PLA film has low heat resistance and usually starts to soften at around 60°C, which limits its application in high temperature environments.

7. **Breathability**: PLA film has a certain degree of breathability, which may be an advantage for some food packaging applications.

8. **Food safety**: PLA film is considered food-safe and can be used for food contact materials.

9. **Processability**: PLA film can be processed by traditional plastic processing methods such as film blowing and casting.

Due to these characteristics, PLA film is widely used in food packaging, agricultural films, sanitary products, textiles and other disposable products. However, the biodegradability of PLA film requires specific industrial composting conditions to achieve, so it may not be more environmentally friendly than traditional plastics in areas without appropriate treatment facilities. When choosing PLA film, the matching of its performance characteristics with specific application requirements should be considered.
