Abstract:
1. A packaging pouch made of a flexible mono or multilayer film for packaging viscous jelly and/or gravy matrix food, in which a thermo cycle such as retort, pasteurisation, hot filling or aseptic conditions is applicable, wherein the surface of a layer of the film forming the pouch inner walls or a surface coating on the film in contact with food comprises a substance having the effect that the surface tension of the layer or the surface coating on the layer is 24 mN/m or less and the pouch inner walls in contact with food exhibit easy flow properties, wherein the substance comprises a graft polymer having a polyolefin based acrylic copolymer backbone with the general structure with R═H, CH or a graft polymer having a polysiloxane based acrylic copolymer backbone with the general structure with R═H, CH or a graft polymer having a polysiloxane/polyolefin based copolymer backbone with the general structure with R═H, CH or a block structure with the extended formula with the general structure or a micro-dispersion of ultra high molecular weight siloxane polymers.
