FAQs
What is polylactic acid?
Polylactic acid (PLA) is a biodegradable plastic made from renewable resources such as plant-based materials like corn starch or sugarcane. These materials are fermented into lactic acid, which is then polymerized to form PLA. The molecular structure of PLA consists of lactic acid monomers, and it possesses excellent processability and high biocompatibility. PLA is commonly used to manufacture disposable tableware, packaging materials, and medical and drug delivery devices. Due to its renewable source and favorable properties, PLA is considered an environmentally friendly alternative material.
Is polylactic acid toxic?
Polylactic acid (PLA) is generally considered non-toxic. As it is derived from plant-based materials and has good biocompatibility, PLA is widely used in medical and food contact materials. However, under extreme conditions, PLA may degrade and release trace amounts of lactic acid or other byproducts, but these substances are typically well-tolerated in the human body. Therefore, PLA does not exhibit significant toxicity.
Is polylactic acid biodegradable?
Polylactic acid (PLA) is a biodegradable plastic. Under suitable environmental conditions, PLA can be broken down by microorganisms into water and carbon dioxide, usually taking several months to years depending on factors such as temperature, humidity, and microbial activity. The biodegradability of PLA makes it an environmentally friendly material, widely used as an alternative to traditional petroleum-based plastics, especially in packaging and disposable products, offering significant environmental benefits.
