A heat-shrinkable film includes outer layers containing a polyester resin,
and at least one inner layer being arranged between the outer layers and
containing an olefinic resin including at least one
ethylene-propylene-butene terpolymer. The film has an interlayer bonding
strength between the inner layer and the outer layer of 3.0 N/15-mm or
more. The inner layer may contain the ethylene-propylene-butene
terpolymer in an amount of 45 percent by weight or more based on the
total weight of the inner layer. The heat-shrinkable film is excellent in
strength, abrasion resistance, solvent resistance, dimensional stability,
and optical transparency, exhibits high shrinkability and high
flexibility as a result of heating, and thereby yields beautiful finish
after shrinkage. The heat-shrinkable film can be suitably recycled after
use.
