HEAT-SHRINKABLE LAYERED FILM, MOLDED ARTICLE COMPRISING THE FILM, AND HEAT-SHRINKABLE LABEL AND CONTAINER |
摘要 |
<p>The present invention provides a heat-shrinkable laminated film including at least two layers, in which the first layer is composed of at least one kind of a polylactic acid series resin as the main component and the second layer is composed of at least one kind of a polyolefin series resin as the main component. Heat shrinkage ratio of this film in the film main shrinking direction is 30% or more when dipped in warm water of 80°C for 10 seconds. Since this heat-shrinkable laminated film is made from a plant-derived resin, it promotes a use of biomass. Also, as this film exhibits excellent shrinkage property in low temperature, film rigidity, shrink finishing quality, and small natural shrinkage ratio, the film is suitably used for a molded product which requires heat shrinkage property, specifically, it is suitably used for shrinkable label.</p> |
