RESIN COMPOSITION FOR MOISTURE-ABSORBING PACKING FILM CAPABLE OF PROVIDING A MOISTURE-ABSORBING FILM WITH HIGH MOISTURE ABSORPTIVITY, AND A MOISTURE-ABSORBING FILM FOR PACKING USING THE SAME

摘要

PURPOSE: A resin composition for a moisture-absorbing packing film is provided to have excellent moisture absorption and maintaining effect, to not generate contamination, to be used easily, and to provide a moisture absorbing film with excellent physical property.;CONSTITUTION: A resin composition for a moisture-absorbing packing film comprises a polyethylene-based resin, and additionally comprises a polyacrylic acid partial sodium salt as a moisture absorbent. The moisture absorbent is 0.5-4 weight% based on the total weight of the resin composition. A manufacturing method of a moisture-absorbing film for packing comprises: a step of manufacturing pellets by compounding polyethylene-based resin and polyacrylic partial sodium sa and a step of blow extrusion by adding the polyethylene resin into the pellet.;COPYRIGHT KIPO 2013
