Title:
ELONGATED LAMINATED SUBSTRATE, ELONGATED SHEET ROLL, AND METHODS FOR MANUFACTURING THESE
Document Type and Number:
WIPO Patent Application WO/2023/234377
Kind Code:
A1
Abstract:
This elongated laminated substrate has: a substrate that has a prescribed length; and two polymer layers that are respectively provided to the two sides of the substrate, the two polymer layers each containing a tetrafluoroethylene-based polymer, each having a prescribed thickness, and each being such that the value of a root-mean-square slope Sdq obtained by measuring the surfaces on the sides facing the substrate is 5 μm/mm or lower. This elongated sheet roll has a cylindrical winding core and an elongated laminated substrate wound about the outer peripheral surface of the winding core, the elongated laminated substrate having a substrate that has a prescribed length, and two polymer layers that are respectively provided to the two sides of the substrate and that each contain a tetrafluoroethylene-based polymer and each have a prescribed thickness, the total thickness of the two polymer layers being a prescribed factor relative to the thickness of the substrate, the thickness of one polymer layer from among the two polymer layers being a prescribed factor relative to the thickness of the other polymer layer, and the value of the product of the total thickness of the elongated laminated substrate and the curvature at the outside diameter of the winding core being less than 0.0015.
