Methods for making resin-impregnated self-adhering or heat-sealable papers by impregnating a raw absorbent paper with an aqueous dispersion of a self-cross-linking resin in which the average diameter of the resin particles is less than 2 microns and, in the same or in a separate step, applying an aqueous suspension of a thermoplastic resin to the paper surface which is to be self-adhering or heat-sealable, the average diameter of the thermoplastic resin particles being over 20 microns. Self-adhering or heat-sealable papers produced by these methods.

Resin-impregnated self-adhering or heat-sealable papers and method of

Method for making highly resin-filled paper on a paper machine employing a fiber slurry having therein a non-ionic resin in an amount of at least 30 percent (dry resin weight based on dry fiber weight), said resin being combined with the fiber slurry as a dispersion comprising a cationic and a non-ionic dispersing agent.
