Method for manufacturing medical tape

A method for manufacturing a medical tape, wherein

• the medical tape includes:
• an elastic base member portion having stretchability for covering a wound and a skin around the wound;
• an adhesion portion having a function of sticking and holding the elastic base member portion on the skin;
• a release portion having a function of protecting the adhesion portion;
• and
• a non-stretchable effective shrink force holding portion having flexibility and restorability,
• the effective shrink force holding portion, the elastic base member portion, the adhesion portion, and the release portion are provided in this order,
• the method comprises the steps of:
• layering a solution polymer that later forms the elastic base member portion over a substantially arcuate concave inner surface of the effective shrink force holding portion bent into substantially arcuate concave shape in cross section under an external force, thereby obtaining a two-layered structure configured by the effective shrink force holding portion and the solution polymer, and drying the solution polymer to complete film formation of the elastic base member portion and lamination of the effective shrink force holding portion and the elastic base member portion, thereby obtaining a two-layered structure configured by the effective shrink force holding portion bent into substantially arcuate concave shape in cross section and the elastic base member portion;
• and
• subsequently, removing the external force applied on the effective shrink force holding portion to cause the effective shrink force holding portion to exhibit restorability, thereby obtaining a two-layered structure configured by the elastic base member portion in a state of retaining the effective shrink force and the effective shrink force holding portion, and
• the effective shrink force retained in the elastic base member portion is released by removing the effective shrink force holding portion at a time of use.
