Title:
HEAT-SHRINKABLE LAMINATED FILM
Document Type and Number:
Japanese Patent JP3914656
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a heat-shrinkable film with a specific gravity of below 0.96 without damaging the high transparency, high glossiness, excellent low temp. shrinkability and excellent printability possessed by a polystyrenic resin.
SOLUTION: A laminate is formed by providing an upper surface layer and a rear surface layer both of which comprise a styrenic resin on both surfaces of an intermediate layer consisting of an olefinic resin with a density of below 0.94 g/cm3 and an adhesive resin. The thicknesses of the respective layers of the laminate are set to (upper surface layer + rear surface layer)/intermediate layer=1/1-1/6 and this laminate is stretched by a draw ratio of 2-6 in at least a uniaxial direction.
