Abstract:
PROBLEM TO BE SOLVED: To provide a normal temperature-shrinkable film capable of conducting high-speed packaging without the need for high temperature for shrinkage.SOLUTION: A normal temperature-shrinkable film satisfies inequality (1): L1≥0.5×L0×(x+1) and inequality (2): L1-L2≥0.1×L0×(x-1), provided that in the inequalities (1) and (2), x, L0, L1, and L2 show the following values: in a temperature between 0°C and 40°C, a tension is applied to the normal temperature-shrinkable film having an initial length L0 to elongate the film in x-times increments. The length of the film, 1 second after the tension is released, is L1; and the length thereof, 10 seconds after the tension is released, is L2.SELECTED DRAWING: None
