Title:

HEAT-SHRINKABLE LAYERED FILM, MOLDED ARTICLE COMPRISING THE FILM, AND HEAT-SHRINKABLE LABEL AND CONTAINER

Document Type and Number:

WIPO Patent Application WO/2006/075634

Kind Code:

A1

Abstract:

A layered film which comprises at least two layers, i.e., a first layer comprising at least one polylactic acid resin as a main component and a second layer comprising at least one polyolefin resin as a main component, and has a degree of heat shrinkage in the main shrinkage direction of 30% or higher through 10-second immersion in 80°C water. Because of the use of the plant-derived resin, the layered film can promote biomass utilization. The film is excellent in low-temperature shrinkability, rigidity, and finish after shrinkage and is reduced in spontaneous shrinkage. The heat-shrinkable layered film is hence suitable for use as a molded article required to have heat shrinkability, in particular, a shrink label, etc.
