To provide a heat-shrinkable laminated film which excels in heat shrinkage characteristics, transparency, and interlayer adhesion at an ordinary temperature, is hard to peel even if treated at a high temperature, is restrained from whitening that occurs when bending the film during processing or the like, and is suitably used for a shrink package, shrink binding package, a shrink label, or the like.

The heat-shrinkable laminated film is formed by extending in at least one direction a film which has two-type three-layer laminate constitution of A layer/B layer/A layer, wherein A layer is composed of a resin composition which includes a polyester based resin as a principal component, B layer is composed of a resin composition which includes 5-90 mass% of a styrene unit; 5-30 mass% of a conjugated diene unit; 0.2-2.0 mass% of a maleic anhydride unit; and 0-40 mass% of an ethylene terephthalate unit, and the rate of heat shrinkage in the main contraction direction when being immersed for 10 seconds into hot water at 80°C is at least 30%.
