POLYMERIC COMPOSITION, METHOD FOR PRODUCING NON-STRETCHED FILM, NON-STRETCHED FILM, HEAT-SEALING MATERIAL, AND PACKAGING MATERIAL

摘要

Disclosed is a polymeric composition comprising a propylene polymer and an ionomer containing an ethylene-a,ß-unsaturated carboxylic acid copolymer and an ethylene-a,ß-unsaturated carboxylic acid-a,ß-unsaturated carboxylic acid ester ternary polymer, wherein the melt flow rate (MFR) of the ionomer at a processing temperature (under a load of 2160 g) when forming a film by melt T-die casting is 50 to 250% of the MFR of the propylene polymer under the same conditions.
