HYDROPHOBIC PAPER OR CARDBOARD WITH SELF-ASSEMBLED NANOPARTICLES AND METHOD FOR THE PRODUCTION THEREOF

摘要

A hydrophobic paper or cardboard that has self-assembled silicon-oxide nanoparticles with functional silane groups and fluorocarbonated compounds linked directly to cellulose fibers of at least one of the surfaces thereof, with a Cobb value of 8 to 25 g/m 2 and water contact angles of 100 to 140 degrees, which can be used for packing foodstuffs. The hydrophobic paper or cardboard may be printed, is recyclable and exhibits improved adhesion in areas requiring adhesive bonding of paper or cardboard.
