摘要 |
<p>The present invention provides a multi-layer resin film having excellent oxygen gas barrier properties, particularly even at high humidity, and further having no chlorine content. The multi-layer resin film of the present invention has a biaxially-stretched polypropylene resin film, an adhesive layer formed on at least one surface of the polypropylene resin film, and a polyvinyl alcohol resin layer formed on the adhesive layer, wherein the polyvinyl alcohol resin layer has a value of crystallinity parameter (CP (M//) ORTHOGONAL ) not less than 0.8. The multi-layer resin film of the present invention can be prepared by forming an adhesive layer on at least one surface of an unstretched polypropylene resin film; stretching the film in one direction; forming a polyvinyl alcohol resin layer on the adhesive layer; and stretching the film in another direction perpendicular to the direction of previous stretching.</p> |
