<p>PROBLEM TO BE SOLVED: To prevent a shrinkable label with a cutting line from being unexpectedly broken during distribution process of commodities, etc., by improving impact-resistant bag breaking properties of the label in a beverage-filled plastic container 20 (especially a PET bottle, etc., with a panel 21 for absorbing change in inner pressure on the trunk) mounted with the shrinkable label with the cutting line. SOLUTION: This container has bunk-like thick parts (13) extended on both sides along a perforation in which the cutting line (11) of the mounted shrinkable label is a line of holes (12) dotted in the longitudinal direction of a tube, and thick parts (14) which is thinner than the thickness of the bank-like thick parts (13) and thicker than the original thickness of the film are formed on the hole edges between holes. The bag is prevented from being broken when falling down impact is given as a reinforcing effect of the thick parts (13) and (14). Cutting of the label is also easy when the label is peeled off after use (when the container and the label are classified and collected). The cutting line (11) is formed by intermittently irradiating the film surface with a laser beam.</p> |
