PRODUCTION METHOD OF CYLINDRICAL SHRINK MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide a cylindrical shrink material enabling affixing of a film end surface to be easily checked for making a shrink film cylindrical and prevent harmful solvent to the human body to be applied. SOLUTION: The shrink film 10 is gradually rolled in the width direction of the shrink film 10 from the one end side in the longitudinal direction of the shrink film 10 in a way that one end in the width direction of the shrink film 10 is gradually superposed upon the other end in the width direction of the shrink film 10 from the one end side in the longitudinal direction of the belt shaped shrink film 10. An adhesive layer is formed by direct coating of adhesive with a coating member on at least one surface of opposite surfaces at the one end and the other end in the width direction of the rounded shrink film 10, and the opposite surfaces are connected by the adhesive layer to form a cylindrical shrink film 10 at the one end and the other end in the width direction of the rounded shrink film 10.
