PLA, or polylactic acid, is a thermoplastic derived from renewable sources such as cornstarch or sugar cane. As a result, it is considered to be a more environmentally friendly alternative to traditional plastics made from petroleum. PLA can be used to produce a wide variety of products, including packaging, foodservice items, and medical devices. It is also widely used in 3D printing. In terms of appearance, PLA is typically translucent and has a milky-white color. However, it can also be found in a range of other colors. When it comes to its properties, PLA is strong and rigid, making it well suited for applications where durability is important. Additionally, PLA is heat-resistant and can be easily molded into various shapes.
