Title:
FILM FOR STENCIL PAPER OF THERMAL STENCIL PRINTING AND STENCIL PAPER USING THE FILM
Document Type and Number:
Japanese Patent JP2002079776
Kind Code:
A
Abstract:
To provide a film for thermal stencil printing which is perforated with low energy and excellent in perforation sensitivity.
The biaxially oriented film for stencil paper of thermal stencil printing is constituted mainly of a thermoplastic resin for which the melting energy is 3-11 cal/g. When the breaking extension percentage in the width direction of the thermoplastic resin is made ET(%) and the breaking strength ST (kg/mm2) and when the breaking extension percentage in the lengthwise direction thereof is made EM(%) and the breaking strength SM (kg/mm2), at least one of ETD and EMD is 70-100% and the following formulas (1) and (2) are satisfied in respect to the film; ST/ET×100≤50 (1), SM/EM×100≤50 (2).
