Safety and regulatory aspects of plastics as food packaging materials
Baldev Raj and R.S. Matche, Central Food Technological Research Institute, India
Polymeric materials are used extensively in food packaging. In addition to the basic polymers, plastics also contain additives added in small quantities to alter the properties of the polymers in the desired way and simplify their processing. These additives along with low-molecular-weight non-polymeric components, which may remain in plastic packaging materials, possess high mobility. It is likely that some transfer of these low-molecular-weight non-polymeric components will occur from the plastic packaging material into the packaged content, thereby contaminating the product ...
