Packaging pouch with food flow properties

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,
