POLYMER COMPOSITION, FILM AND CONTAINER

摘要

PROBLEM TO BE SOLVED: To obtain a polyolefin-based polymer composition that is used in the sealing layer of a film so as to make a sealing strength of the film to glass satisfy both sealing properties and opening properties and have an excellent appearance of glass release surface from which the film is peeled.

SOLUTION: The polymer composition comprises specific amounts of a vinyl compound polymer (A) and an olefin polymer and has the ratio of the melt flow rate of the vinyl compound polymer (A) to that of the olefin polymer of 1-200. The vinyl compound polymer (A) is a polymer comprising a specific amount of a vinyl compound (X) unit represented by the general formula: CH2=CH-R (wherein R is a secondary alkyl group, a tertiary alkyl group or an alicyclic hydrocarbon group), a specific amount of a 2-20C α-olefin unit and a specific amount of an unsaturated carboxylic acid unit and having a melt flow rate of 0.1-300 g/10 minutes.
