Title:
WORK PROCESSING SHEET AND PROCESSED WORK MANUFACTURING METHOD
Document Type and Number:
Japanese Patent JP2022151239
Kind Code:
A
Abstract:
To provide a work processing sheet excellent in resilience after being released from expansion, and a processed work manufacturing method using the work processing sheet.SOLUTION: A work processing sheet includes a substrate and an adhesive layer laminated on one side of the substrate, when a tensile test is performed on the substrate at a tensile speed of 200 mm/min at 23°C, a hysteresis loss calculated by the following formula (I) is 0.53 J or less. In the formula, N represents test force (N), L represents elongation (%), NL+1 represents test force (N) at L+1, and L+1 represents elongation (%) of the following item.SELECTED DRAWING: None
