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.

Composition comprising recycled resin and ethylene-acrylic acid copolymer and preparation method thereof

A paper coating composition, methods for making the same, and a coated paper. The paper coating composition comprises a solvent, an ethylene-(meth)acrylic acid copolymer, a basic compound, and a polycarbodiimide-based curing agent, wherein the polycarbodiimide-based curing agent has a carbodiimide group equivalent of about 150 to about 350. The coating of the coated paper likewise comprises an ethylene-(meth)acrylic acid copolymer crosslinked by N-acylurea groups.
