Abstract
An object is to provide a biaxially stretched film which allows tacking, is heat-stickable, is less liable to unevenness in thickness, breakage, whitening, unevenness, etc. i.e. has stretching stability and is decomposable in the natural environment. It comprises a polylactic acid-family polymer as its major component, and has a storage elastic modulus E′ at 120° C. of 100-230 MPa as measured using a test method concerning temperature dependency of the dynamic viscous elasticity under JIS K7198.
