NON-CORE SHEET ROLL AND MANUFACTURING METHOD FOR NON-CORE SHEET ROLL

摘要

PROBLEM TO BE SOLVED: To provide a non-core sheet roll which, although it is a non-core and a form as a roll is retained, can be turned into a sheet by small force in order to reduce waste as much as possible.;SOLUTION: In the non-core sheet roll comprising a thermoplastic polymer, the sheets are temporarily adhered to each other at both ends in a width direction of the sheet roll to retain the form as the roll. The non-core sheet roll and the manufacturing method for the non-core sheet roll are preferably constituted such that the temporary adhesion is performed in a limited area at both ends of the sheet roll and adhesion strength is lower than strength of the sheet.;COPYRIGHT: (C)2008,JPO&INPIT
