Document Type and Number:
Japanese Patent JP2008307889
Kind Code:
A
Abstract:
To provide a method of manufacturing multilayer stretch film which is a laminate of a thermoplastic resin having a melting point of 125C or higher and a vinyl alcohol resin containing 1,2-diol unit in a side chain, and shows excellent appearance even when the film is stretched at a high stretching ratio of 15 times or more.
A multilayer stretch film comprises: a layer containing the vinyl alcohol resin (A) having 1,2-diol unit in a side chain; a layer containing the thermoplastic resin (B) having a melting point of 125 to 300C; and a layer of an adhesive resin (C) used between both layers, wherein a thermoplastic resin having a melting point higher than the stretching temperature of the laminate is used as the adhesive resin (C).
