FIELD: packaging materials.
SUBSTANCE: present invention relates to improved PVDC composition including a certain cinnamate dienophile that meets the requirements of food contact, which has an optimal balance of effectiveness in preventing color changes under the influence of radiation in the absence of negative effects on the barrier properties, in particular the cinnamate Formula (I)
wherein each of substituents R1, R2, R3,which are the same or different from each other, represents H or C1-C12-hydrocarbon group, to layers made of the composition, to multi-layer combined structures containing such a layer, as well as to the use of these combined structures for packaging, in particular for food packaging.
EFFECT: invention can be used for packaging, in particular for food packaging.
