Since its invention in the 1930s, plastic packaging has posed two challenges: its dependence on petroleum and the problem of waste disposal. Over the past five years packaging suppliers have been introducing various forms of biodegradable plastics made from a variety of plants, in the main corn. The market of biodegradable polymers at the present is growing based on projections that consumers and recycling regulations will drive demand for environmentally-friendly packaging. Market introduction has started successfully all over Europe. Most important application sectors of biodegradable polymers today: organic food and service packaging, shopping bags, catering products, bio waste bags, mulch films, horticulture auxiliaries. At the Latvia University of Agriculture faculty of Food Technology the following tasks of some biodegradable polymer testing for food applications were carried out: (1) plasticized PHB films were used for sour cream and salad with meat and mayonnaise packaging; (2) PLA film influence on the quality indices of rye bread at the storage time and their suitability for bread packaging was evaluated; (3) with the aim to check the published data of biodegradable PLA packaging film special suitability to provide longer shelf life of fresh fruits and vegetables, some in Latvia cultivated fruit storage were tested.
