Packaging pouch with food flow properties

摘要

In 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, pasteurization, hot filling or aseptic conditions are applicable, the surface of a layer of the film forming the pouch inner walls or a surface coating on the film being 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 being in contact with food exhibit easy flow properties.

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
[CH2CRCOO(CH2)pCH3]x[CH2CR1COO(CH2)2(CF2)qCF3]y with R═H, CH3; R1═H, CH3; 0y/x>0.03 or a graft polymer having a polysiloxane based acrylic copolymer backbone with the general structure
[CH2CRCOO(CH2)p(SiO(CH3)2)m(SiO(CH3)3)]x[CH2CR1COO(CH2)2(CF2)qCF3]y with R═H, CH3; R1═H, CH3; 1y/x>0.03 or a graft polymer having a polysiloxane/polyolefin based copolymer backbone with the general structure
[CH2CRCOO(CH2)p(SiO(CH3)2)m(SiO(CH3)3)]x[CH2CR1COO(CH2)pCH3]y with R═H, CH3; R1═H, CH3; 1y/x>0.03 or a block structure with the extended formula
CH3(CH2)12CH2COO(CF2)8CONHNHCOO(CF2)8COONHNHCO(CF2)8COOCH2(CH2)12CH3 with the general structure or a micro-dispersion of ultra high molecular weight siloxane polymers.
