Description
前記伸縮性基材部の上層に、前記伸縮性基材部を皮膚に貼付し保持する機能を有する粘着部を積層し、前記粘着部の上層に該粘着部を保護する機能を有する剥離部を積層する工程、
前記製膜土台部を前記伸縮性基材部から剥離させて取り除くことで、前記溶液ポリマーの成形収縮に伴い生じる残留収縮力を減少させた状態の前記伸縮性基材部を得て、前記伸縮性基材部、前記粘着部、前記剥離部からなる3層の構造体を得る工程、及び
前記3層の構造体の前記伸縮性基材部に、前記伸縮性基材部を保持する機能を有する支持体部を積層する工程、を備える医療用テープの製造方法である。
この製造方法によって得られる医療用テープは、溶液ポリマーで製膜された伸縮性機能を有する伸縮性基材部と、前記伸縮性基材部を皮膚に貼付し保持する機能を有する粘着部と、前記粘着部を保護する機能を有する剥離部と、該医療用テープの使用時に、前記伸縮性基材部を保持する機能を有する支持体部を備え、製造工程において、前記溶液ポリマーの製膜を可能とする非伸縮機能を有する製膜土台部を前記伸縮性基材部から剥離して取り除いて製造されることを特徴とし、前記支持体部、前記伸縮性基材部、前記粘着部、及び前記剥離部がこの順に積層されている医療用テープである。
本発明の医療用テープの製造方法において、上記工程以外の工程については、任意でよく、本発明の効果を奏することができる限りにおいて特に限定されるものではない。
