Beschreibung
Zusammenfassung:	Provided is an adhesive composition including an ethylene-acrylic acid copolymer and a post-consumer recycled resin (PCR), wherein the ethylene-acrylic acid copolymer has a melt index (190° C., 2.16 kg, ASTM D1238) of 1 to 30 g/10 min, and the PCR has a melt index (190° C., 2.16 kg, ASTM D1238) of 1 to 10 g/10 min, and a preparation method thereof, which can have excellent processability, low gel content, and excellent adhesive strength by easily distinguishing a certain level of PCR resin by a capillary rheometer and mixing the PCR resin with an ethylene-acrylic acid copolymer.
