POLYACRYLIC ADHESIVE FOR USE IN TISSUE PAPER LAMINATING

The present invention relates to a method for manufacturing a multi-ply tissue paper, wherein a first tissue is adhesively bonded to a second tissue using an aqueous, repulpable adhesive composition comprising an alkali soluble acrylic copolymer, The present invention also relates to a multi-ply tissue paper obtained by said manufacturing method.

MULTIWALL PAPER-BASED PACKAGING STRUCTURES

A paper-based packaging article includes outer and intermediate paper plies and an inner polymer film ply. A first adhesive layer is disposed between the inner and intermediate paper plies for gluing the inner polymer film ply to the intermediate paper ply. A second adhesive layer is disposed between the intermediate and outer paper plies for gluing the intermediate paper ply to the outer paper ply. The first and second adhesive layers overlap and are coaligned. The outer and intermediate paper plies and the inner polymer film ply are adjoined to form a multiwall structure, wherein the first adhesive layer and the second adhesive layer are coaligned with each other on the multiwall structure. The first adhesive layer comprises a first plurality of adhesive spots and the second adhesive layer comprises a second plurality of adhesive spots, wherein the adhesive spots of the first plurality of adhesive spots do not overlap with the adhesive spots of the second plurality of adhesive spots.
