Title:

POPYPROPYLENE-BASED SYNTHETIC PAPER AND ITS PRODUCTION

Document Type and Number:

Japanese Patent JP2511802

Kind Code:

B2

Abstract:

PURPOSE: To produce a synthetic paper excellent in foldability.
CONSTITUTION: Apolypropylene-based synthetic paper is produced by compounding 100 pts.wt. crystalline polypropylene resin with 50-200 pts.wt. the sum of 30-180 pts.wt. cyclopentadiene petroleum resin having a softening point (ring and ball method) and 20-170 pts.wt. inorg. filler powder, forming the resulting compsn. into a sheet, stretching the sheet to an areal stretching ratio of 9 or higher to give a stretched sheet with a density of 0.05-0.6g/cm3, and thermaly compressing the stretched sheet at 80-160°C under a pressure not making the sheet transparent.
