WIPO Patent Application WO/2012/147665
Kind Code:
A1
Abstract:
Packaging in which a roll is wrapped in a packing material (11, 25), said roll comprising a PVA film (3, 24) wrapped around a cylindrical core (2, 21). Even when condensation forms on the inner peripheral surface or the like of the core (2, 21), in order to hinder water formed from the condensation from penetrating inside the packaging, the packaging is configured so that both ends of the core (2, 21) form protrusions that protrude from the end surfaces of the roll, and that at least a part of the end of the packing material (11, 25) is fixed to the outer peripheral surface (22) of the protrusions.
