Restoring force preserving portion-bonded medical tape and method for manufacturing the same
Abstract:
Provided is a medical tape that has a high effect of alleviating a persistent skin irritation during an application duration caused by a residual shrink force associated with a forming shrinkage.
A medical tape includes an elastic base member portion film-formed of a solution polymer and having an elastic function, a restoring force preserving portion having inelastic, flexible, and restorable functions, an adhesion portion having a function to apply and hold the elastic base member portion on a skin, and a release portion having a function to protect the adhesion portion. The restoring force preserving portion, the elastic base member portion, the adhesion portion, and the release portion are laminated in this order from an upper layer.
