Patent ID: 8728594

Claim:
A label comprising a heat-shrinkable white film as a base material thermally shrinking in the film width direction as the main shrinkage direction, being cut according to an object to be packaged, and bonded at both edges in the film width direction, the tubular body being thermally shrunk so that at least part of the periphery of the object to be packaged is covered with the label, wherein (a) whiteness is 70 or more, or/and voids are contained, the film has a molecular orientation ratio of 3.5 or more and 4.1 or less, (b) a right-angle tear strength in the direction orthogonal to the main shrinkage direction (film longitudinal direction) is 90 N/mm to 300 N/mm, and (c) a tensile break strength in the direction orthogonal to the main shrinkage direction (film longitudinal direction) is 50 MPa or more and 250 MPa or less.
