Document Type and Number:
WIPO Patent Application WO/2018/008736
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a sheet that resists cracking when bent. The present invention relates to a sheet that includes: a fibrous cellulose that is derived from pulp and that has a fiber width of no more than 1000 nm; and a polyvinyl alcohol resin. The tensile strength of the sheet is at least 15 MPa.
