The adhesive composition comprising emulsion polymers and microspheres and articles made therefrom are provided. The adhesive is particularly suitable for packages for consumer products that provide sufficient strength and thermal insulation while reducing the overall basis weight of the substrates.

The present invention relates to a hyaluronic acid-based dissolving film, a production method thereof, and a release liner used for the same, and more particularly to a method for producing a hyaluronic acid-based dissolving film that provides a hyaluronic acid-based dissolving film having high performance with high productivity through a continuous production process to allow mass production of the dissolving film, a hyaluronic acid-based dissolving film produced by the method, and a release liner suitable for the dissolving film.

An aqueous emulsion may include an ethylene-vinyl alcohol copolymer (A) as a dispersant and a polymer (B) which contains an ethylenically unsaturated monomer unit as a dispersoid, wherein the ethylene-vinyl alcohol copolymer (A) has an ethylene unit content of 1 mol % or more and less than 20 mol %; and a crystallinity in water at 30° C. (Cw (30° C.)) and a crystallinity in water at 70° C. (Cw (70° C.)) as determined by pulse NMR satisfying formula (I). Such aqueous emulsions can form fewer aggregates and exhibit excellent water-resistant adhesiveness and excellent film formability.
