Jinwei Machinery PLA Blister Packaging Sheet Equipment

Description :

　　Polylactic acid (PLA) is a new type of biobased and renewable biodegradable material made from starch raw materials derived from renewable plant resources such as corn and cassava. Starch raw materials are saccharified to obtain glucose, which is then fermented by a specific strain of bacteria to produce high-purity lactic acid. This is then synthesized through chemical synthesis methods to produce polylactic acid with a fixed molecular weight. It has good biodegradability and can be completely degraded by microorganisms in nature under specific conditions after use, ultimately producing carbon dioxide and water without polluting the environment. This is beneficial for protecting the environment and is recognized as an environmentally friendly material.

　　Polylactic acid has good thermal stability, processing temperature of 170-230 ℃, and good solvent resistance. It can be processed in various ways, such as extrusion, spinning, biaxial stretching, and injection blow molding. Products made from polylactic acid are not only biodegradable, but also have good biocompatibility, glossiness, transparency, hand feel, and heat resistance. They also have certain bacterial resistance, flame retardancy, and UV resistance, making them widely used as packaging materials, fibers, and non-woven fabrics. Currently, they are mainly used in clothing (underwear, outerwear), industries (construction, agriculture, forestry, papermaking), and medical and health fields.

　　Polylactic acid PLA is a biodegradable resin that can be used for hard packaging of fruits, vegetables, eggs, cooked food, and baked goods, as well as for packaging of sandwiches, cookies, and flowers.
