Title:
EVALUATION METHOD FOR PROTECTIVE SHEET, GLASS PLATE PACKAGING BODY, AND GLASS PLATE PACKAGING BODY MANUFACTURING METHOD
Document Type and Number:
WIPO Patent Application WO/2024/018817
Kind Code:
A1
Abstract:
This evaluation method for a protective sheet used in the packaging of glass plates comprises: a stacking step in which a glass plate (1) and a protective sheet (2) are stacked in a state where particles (3) are interposed between the glass plate (1) and the protective sheet (2); a scratch forming step in which the protective sheet (2) is caused to move relative to the glass plate (1) so that scratches are formed on the surface of the glass plate (1) by the particles (3); and a measuring step in which the depths of the scratches are measured. This configuration reliably prevents a situation in which, when packaging the glass plate, recessed scratches are formed on the surface of the glass plate due to foreign matter.
