PROBLEM TO BE SOLVED: To avoid an increase in cost and to provide a sealing strip which insures easy unsealing by using an expensive heat-shrinkable film only on a part requiring heat shrinkage in the sealing strip. SOLUTION: The sealing strip 3 is to be wound around the packaging container A, wherein only a lower part positioned on a bottom of the container A is formed to be heat-shrinkable along the direction of the strip. To embody this, an upper half 31 of the sealing strip is formed of a non-prestretched film or a paper material, a lower half 32 is formed of a prestretched film which can be heat-shrunk along the direction of the strip, and both halves are joined. |
