<P>PROBLEM TO BE SOLVED: To provide an adhesive for a packing bag, which is excellent in adhesiveness to a resin film, facilitates cleaning of a coater, and rarely causes adhesive oozing out to a paper substrate. <P>SOLUTION: The adhesive for a packing bag comprises (A) a (meth)acrylic emulsion and (B) a rubber-based emulsion, in which the solid content of (A) the emulsion has a glass transition temperature of -40°C or lower and the solid content of (B) the emulsion has a glass transition temperature of -10°C or lower. The adhesive for a packing bag further comprises (C) a copolymer emulsion of ethylene with a carboxylic acid derivative containing an ethylenic double bond, in which the solid content of (C) the emulsion preferably has a glass transition temperature of -10°C or lower. <P>COPYRIGHT: (C)2012,JPO&INPIT |
