Zusammenfassung: | The invention provides a heat-sealable aqueous resin composition, a film, a laminate, and a method for producing the heat-sealable aqueous resin composition. A heat-sealable aqueous resin composition comprising: a rosin-based resin (A); a biodegradable resin (B) containing a resin having a structure represented by general formula (1) and/or a resin (b1) having a structure represented by general formula (2); and a polyvinyl alcohol (C) having an average degree of saponification of 75-85 mol%, and the content of component (b1) exceeds 50 mass% when the total content of component (A) and component (B) is 100 mass%. General formula (1):-O-(CH2) x-O-CO-(CH2) y-CO-(in general formula (1), x and y may be different from each other and are integers of 1 to 10 inclusive) general formula (2):-O-(CH2) z-CO-(in general formula (2), z is an integer of 3 to 10 inclusive).
