EASILY OPENABLE CONTAINER

摘要

PROBLEM TO BE SOLVED: To provide an easily openable container which has enough sealing force and is easily openable when it is opened and has excellent appearance on a released face in a packaging container, a packaging bag and the like with a non-olefinic resin on a heat sealing face. SOLUTION: The easily openable container with a heat-sealed structure wherein a face of a polymer composition comprising the following ingredients (A), (B) and (C) and a face of a resin except olefinic polymers and with a solubility parameter of 8.0-14.0 are heat-sealed is. provided. The ingredient (A) is 10-60 wt.% olefin polymer except the following ingredient (B) and the ingredient (B) is 30-5 wt.% linear ethylene-α-olefin copolymer being a copolymer of ethylene and a 6-12Cα-olefin prepared by a methallocene catalyst and the ingredient (C) is 80-30 wt.% polymer being a polymer except the olefinic polymers and having a solubility parameter with the absolute value of a difference of at least 0.7 from the solubility parameter of the ingredient (A) olefinic polymer.
