Improved resistance to liquid penetration of paper products may be produced by the use of an improved paper-sizing blend of a paper-sizing fatty acid anhydride and paper-sizing alkyl ketene dimer the weight ratio of the fatty acid anhydride to the alkyl ketene dimer being greater than 1.0 to 1.0 and not exceeding 4.0 to 1.0. The sized paper product also show an improved resistance to wicking and containers made from the paper products show an improved resistance to leakage when subjected to vibratory abuse.

Paper sizing

The stiffness and wet strength of paper products are improved by subjecting the products to high temperature treatment, immediately followed by rewetting. The resultant products have good folding endurance.
