PLA-Based Packaging Materials

The most common use of P LA is for compostable sugarcane trays and in punnets or pallets. A starch derivative, PLA can be manufactured from maize and other plants and is a biodegradable, compostable plastic material. The material is obtainable in a range of blends and can be used in sheet or film form for a diverse range of products including food containers. It can be used for rigid thermoforms, films. 

Purac has invested in new lactides that should potentially provide the food, pharma, and cosmetics industries with cheaper and more effective bioplastic packaging. Netherlands-based Purac, a producer of lactic acid for the food sector, has stated that the new lactides wiU contain L-(-h)- and D-(-)-lactic acids. The new lactides will be sold to companies that will use them to make bioplastics that can withstand greater heat than ever before. The new materials will be suitable for applications as diverse as hot-fill bottles, microwaveable trays, temperature-resistant fibers, and electronics, and will withstand temperatures of up to 175 C. 

NEC Corporation has developed a biodegradable plastic composite that is suitable for personal computer case appHcations. The composite material is made from poly(lactic add) with fibers of the kenaf planfi a herbaceous annual related to cotton, incorporated to provide both increased strength and heat resistance. The material s heat resistance, processabihty, and strength are comparable to those of 

BioPeel is a clear, peelable PLA lidding or flow-wrap film, suitable for use with chilled and frozen products such as fruif vegetables, salads, and sandwiches. BioPeel has a broad sealing window and clarity, is available with antifog, and can be perforated. BioPeel can be tailored to seal and peel to any type of container.
