Container for retort packaging, resin composition, and gas-barrier film prepared therefrom |
摘要 |
The present invention provides a container for retort packaging comprising a laminated film having an outermost layer comprising a layer formed of a cross-linked structure containing ester bonds between poly(meth)acrylic acid (A) and polyalcoholic polymer (B); a resin composition having at least the chemical structures (X) [poly(meth)acrylic acid (A) residue], (Y) [poly(meth)acrylic acid (A)-polyalcoholic polymer (B) residue] and (Z) [metal cross-linked ionic residues], wherein the degree of esterification defined by the equation: degree of esterification=c/(b+c+d) is from 0.01 to 0.5 and the degree of ionization defined by the equation: degree of ionization=c/(b+c+d) is from 0.01 to 0.9 (wherein b, c and d represent the molar ratios of the carbon-oxygen double bond in the chemical structure of the resin composition; and a gas barrier film comprising the same.
