Poly(vinyl alcohol) resin composition comprising cellulose nano fiber and film prepared using the same

摘要

The present invention relates to a polyvinyl alcohol-based resin composition containing cellulose nanofibers and a film using the same, and more specifically, 1 to 20 parts by weight of glycerol (glycerol: GC), a polyhydric alcohol plasticizer, to 100 parts by weight of a polyvinyl alcohol-based resin. A polyvinyl alcohol-based resin composition comprising 0.01 to 0.1% by weight of part and cellulose nanofibers, and a polyvinyl alcohol-based resin film having excellent optical properties and improved tensile strength and elongation, and a method for producing the same. For. The polyvinyl alcohol-based resin composition according to the present invention exhibits excellent optical properties because it has a transmittance of 85% or more on the film, and the manufactured polyvinyl alcohol-based resin film has the advantage of having excellent tensile strength and improved physical properties in stretchability. .
