HEAT-SHRINKABLE LAMINATED FILM

摘要

PROBLEM TO BE SOLVED: To provide a heat-shrinkable laminated film with a specific gravity less than 0.960 enhanced in printability and dimensional stability, using an olefinic resin. SOLUTION: The heat-shrinkable laminated film is obtained by providing an intermediate layer comprising a propylene resin and a petroleum resin between a surface layer and a rear layer both of which comprise a styrenic resin to form a laminate wherein the thicknesses of the respective layers satisfy (surface layer + back layer)/intermediate 1ayer = 1/1.5-1/6 and stretching the laminate at least unidirectionally by 2-8 times.
