PLA (Polylactic Acid) is a biodegradable and bioactive thermoplastic derived from renewable resources like corn starch or sugarcane. PLA is commonly used in 3D printing, food packaging, disposable tableware, and other products. In general, PLA is considered food-safe when used for food packaging and food contact applications. However, it's essential to ensure that the PLA material used is of high quality, food-grade, and certified safe for food contact.
