To provide a transparent biodegradable heat shrinkage laminated film having excellent gloss and shrinkage necessary to heat shrinkage package or particularly excellent low temperature shrinkage.

The biodegradable heat shrinkage laminated film is obtained by orienting a multilayer film having both outer layers each made of a polylactic acid (A) containing an L-lactic acid and a D-lactic acid of 94:6 to 79:21 of a composition ratio and at least one layer made of an aliphatic polyester (B) obtained by mainly synthesizing an aliphatic polyhydric alcohol and an aliphatic dicarboxylic acid or its derivative or made of a mixture (C) of the acid (A) and the polyester (B) so that a ratio of the acid (A) to the polyester (B) of the overall layers is (A):(B)=30:70 to 75:25 wt.% at least in one direction. In this case, a shrinkage factor of the film after the film is dipped in a glycerin at 90°C for 30 min is 20% or more in at least one direction of MD and TD directions of the film.
