POLYMER COMPOSITION, METHOD FOR PRODUCTION NON-STRETCHED FILM, NON-STRETCHED FILM, HEAT SEAL MATERIAL, AND PACKING MATERIAL

摘要

Provided is a polymer composition that contains an ionomer which includes an ethylene-α,ß-unsaturated carboxylic acid copolymer and a ternary polymer of ethylene-α,ß-unsaturated carboxylic acid-α,ß-unsaturated carboxylic acid ester, and a propylene-based polymer, wherein a melt flow rate (MFR) value (under a load of 2160 g) of the ionomer at a process temperature in forming a film by T-die melting casting method is from 50% to 250% based on an MFR value of the propylene-based polymer under the same condition.
