Abstract: The invention relates to a sealant antifog composition for polyester films comprising anionic and non-ionic surfactants in a mixture of amorphous and (semi)crystalline polyesters. The invention also relates to a multi-layer film comprising a sealant layer having the above composition, to the use of said films in food packaging and to the packages obtained therefrom.

Abstract: The present invention refers to a versatile gas-barrier multilayer heat-shrinkable thermoplastic film that, by minimal variations in its manufacturing process, becomes suitable for the manufacture of packages, called “Flowpack”, on horizontal form-fill-seal (HFFS) machines, of tray-lidded packages or of shrinkable packaging bags. This film comprises a first outer sealant layer, a second outer polyester layer, an inner barrier layer, no polyamide or polyester inner layer(s), no polyolefin layers positioned between the barrier layer and the sealant layer and at least a polyolefin bulk layer of specific relative thickness placed between the inner barrier layer and the outer polyester layer.
