Abstract: A polymer composition [composition (M)], said composition (M) comprising i) at least one polyglycolic acid polymer [polymer (PGA)] and ii) at least one amorphous polyester [polymer (APES)], said polymer (APES) being present in the composition (M) in an amount of at least 0.10 and of at most 45 wt %, with respect to the combined weight of polymer (PGA) and polymer (APES). Method of making such composition and method of producing a multilayer stretched product from such composition.

Abstract: The invention pertains to an improved PVDC composition including certain cinnamate dienophiles qualified for food contact, which possess an optimized balance of effectiveness in preventing discoloration upon exposure to radiation, with no negative impact on the barrier properties, in particular cinnamates of formula (I), wherein: —each of R1, R2, R3, equal to or different from each other, is H or a C1-C12 hydrocarbon group, to layers made therefrom, to multi-layer assemblies comprising the same, and to the use of said assemblies for packaging, in particular for packaging foodstuffs.
