FIELD: drinks packaging.
SUBSTANCE: invention relates to the field of packaging for drinks and relates to a laminate for a paper container and a paper container. One aspect of the invention relates to a paper container laminate. The laminate includes a laminate where a paper base material layer, an adhesive layer, and a barrier layer are laminated in that order. The adhesive layer comprises a resin composition (A) containing one or more types of resin selected from the group consisting of ethylene/unsaturated carboxylic acid/unsaturated carboxylic acid ester copolymer, ethylene/unsaturated carboxylic acid copolymer and ethylene/unsaturated carboxylic acid ester copolymer and comprising at least an ethylene/unsaturated carboxylic acid/unsaturated carboxylic acid ester copolymer. The melt flow rate (MFR) of the resin composition (A) at 190°C and under a load of 2160 g is 9.0 g/10 min or less, based on JIS K7210: 1999.
EFFECT: invention provides a paper container laminate having excellent adhesion between an adhesive layer and various barrier layers while suppressing blistering during assembly of a paper container and a laminated paper container.
