CONTAMINATION OF FOODSTUFF BY PLASTIC PACKAGING. A QUESTION OF RESPONSABILITIES
Good nutrition is the most important environmental influence for health. The appropriate foodstuff can hardly be conserved or transported without a suitable packaging. A vast majority of packaging materials consists of plastic because of its outstanding mechanical properties. The polymer barrier will protect the food against all kinds of environmental influences and provides the possibility of important information for manufacturer and consumer. However, these plastic packagings can contaminate the packed food, resulting in organoleptic changes or even health hazards for the ultimate consumer. This paper focuses on the influences that determine the level of this contamination. The migration tendency is partly determined by the raw material manufacturer and by his choice of plastic additives; also the selection of the optimal plastic combination for particular goods will be important. But temperature changes, shocks, vibrations during transport of the packed goods, and storage conditions by the retailer or end-user often seem to be neglected. Examples of migration tests with high density polyethylene are described and indicate that specific migration of plastic additives into foodstuffs depend strongly on these final links in the food processing chain. Comprehensive information on the packed food and a sense of responsibilities, both of the customer and retailer, will lead to the supply of plastic packed foods more harmless to human health.
