From an environmental point of view biodegradable polymers offer an interesting alternative to classical plastics. Example of polymers completely made from renewable resources, are polyesters such as polylactide (PLA). Its properties are especially suitable for food packaging. PLA can be used in a wide range of packaging applications for example fruit and vegetable. The novel polymer is forging roles in thermoformed trays and containers as well as shopping bags and labels. It is convenient to processes on conventional extrusion and thermoforming equipment. PLA is compostable under industrial conditionsall of packaging is certified in according to the standard EN13432:2000 by DIN CERTCO and qualify to use IBAW compostability logo. In additioni, increased efficiencies in the manufacturing process and the rising prices of petrol oil have led to the cost of PIA becoming comparable to other conventional plastic materials.
