Title:
COMPOSITION FOR FOOD PACKAGING BASED ON VINYL AROMATIC RESIN CONTAINING A MINERAL PLATY FILLER IN THE FORM OF NANOPARTICLES
Document Type and Number:
WIPO Patent Application WO2004012998
Kind Code:
A3
Abstract:
The invention relates to a preparation used for packaging food recipients. Said preparation is based on styrene crystal resin or resin reinforced against chocks in which mineral platy filler such as clay or zirconium phosphonate is dispersed in the form of nanoparticles. The migration degree of monomers, dimers and trimers of the food packages comprising the inventive composition is very low with respect to food simulates contained in said packages.
