biodegradable PE film backsheet

Polylactic acid (PLA) is a biodegradable thermoplastic polyester commonly used in the manufacture of biodegradable PE film backsheet alternatives or in blending modification with PE films to enhance their biodegradability. The following is an introduction to PLA in biodegradable PE film. Biodegradability: The most significant characteristic of PLA is its biodegradability. In the natural environment, PLA can gradually decompose into carbon dioxide and water under the action of microorganisms, and the decomposition process is relatively fast. Compared with traditional PE films, it greatly reduces long-term pollution to the environment. Good mechanical properties: PLA has high strength and modulus, and its tensile strength is comparable to or even higher than traditional raw material polyethylene (PE) film. At the same time, it has good flexibility and puncture resistance, which can meet general packaging and usage requirements. Thermal stability: PLA has good thermal stability and can maintain its shape and performance stability within a certain temperature range. Its melting point is usually between 150-180 ℃, and it has good processing performance. It can be made into thin films through various processes such as blow molding and casting. Transparency and glossiness: PLA backsheet film for sanitary napkin have good transparency and glossiness, high appearance quality, and can clearly display packaging contents with good visual effects, which makes them advantageous in some application fields with high appearance requirements.
