english How to improve the environmental performance of plastic packaging film
2025-04-12
The environmental performance of plastic packaging film can be improved from the following aspects:
1. Use degradable materials
Use biodegradable plastics, such as polylactic acid (PLA), polyhydroxyalkanoate (PHA), etc. These materials can be decomposed into carbon dioxide and water under the action of microorganisms in the natural environment, which can effectively reduce the accumulation of plastic waste.
2. Optimize production process
Improve production process, improve energy utilization efficiency, and reduce energy consumption and pollutant emissions in the production process. At the same time, accurately control production parameters, reduce waste and defective rates in the film production process, and realize effective utilization of resources. For example, the use of advanced extrusion technology can more accurately control the thickness of the film, saving materials while ensuring performance.
3. Strengthen recycling
Establish a complete recycling system to improve the recycling rate of plastic packaging film. Through publicity and education, enhance the public's environmental awareness and encourage consumers to classify discarded plastic films. Enterprises can also cooperate with recycling plants to develop efficient recycling and processing technologies, wash, crush, granulate and process the recycled plastic films, and reuse them in the production of plastic films or other plastic products.
4. Research and develop green additives
Add green and environmentally friendly additives such as natural antioxidants and light stabilizers to plastic packaging film to replace traditional toxic and harmful additives. These green additives can not only improve the performance of the film, but also reduce the harm to the environment.
5. Promote reduction design
Try to reduce the use of plastic packaging film while meeting the packaging function. By optimizing the packaging structure design, using lighter and thinner films, or using alternative packaging forms, such as a combination of paper packaging and plastic film, while ensuring the product protection and display functions, the amount of plastic film can be reduced, thereby improving its environmental performance.
