Patent

CA 2573837

Packaging materials made of thermoplastic polymers can readily adhere to pasty and fatty foods. To prevent this adhesion as substantially as possible, as nonstick composition a fatty acid ester of a polyhydric alcohol having at least one fatty acid radical per ester molecule of 19 or more carbon atoms is proposed. This nonstick composition is used in packaging and packaging materials made of thermoplastic polymer, in particular for the packaging of foods. Even at concentrations greater than or equal to 800 ppm in surface-close regions or layers of the packaging, a permanent good nonstick effect can be observed.
