ABSTRACT:
Heat sealable paper can be prepared by applying to a surface-sized paper web a coating of a dispersion comprising a microcrystalline wax and a copolymer of ethylene and acrylic acid or methacrylic acid. The coating can be applied by means of a size press between dryer sections in a paper machine. The coating neither adheres to nor leaves a residue on the heated drums in the dryer section following the size press.
