Abstract:
PROBLEM TO BE SOLVED: To provide a shrink packaging method in which an object to be packaged can be easily shrink-packaged, and a package to be obtained has excellent opening quality, and a heat-shrinkable film suitable for the packaging method.SOLUTION: A shrink packaging method comprises: a process I of coating an object to be packaged 11 by a heat-shrinkable film to form a heat-shrinkable film coated body; and a process II of heating the heat-shrinkable film coated body and heat-shrinking the heat-shrinkable film to obtain a package. In the heat-shrinkable film, (1) an end part parallel with a TD direction of a heat-shrinkable film A12 and an end part parallel with the TD direction of a thermoplastic resin film B13 are formed in a joined state, (2) Elmendorf tear strength of a heat-shrinkable film A in the TD direction is different from Elmendorf tear strength of a thermoplastic resin film B in the TD direction, and (3) the length of the thermoplastic resin film B in the MD direction is shorter than the length of the heat-shrinkable film A in the MD direction.SELECTED DRAWING: Figure 3
