A processing method for increasing stripping resistance of a peripheral envelope of a diaper, which comprises: adding a high molecule water absorption material into wood pulp fibers at a high proportion and wrapping the wood pulp fibers with ultra-thin non-woven cloth (3) to prepare a diaper cotton core body (1), wherein four sides of the ultra-thin non-woven cloth (3) are extended into a diaper peripheral envelope area (6), and a part of the ultra-thin non-woven cloth (3) in the diaper peripheral sealing area (6) is coated with hot melt adhesive for adhesion wrapping the diaper cotton core body (1) that is wrapped with the ultra-thin non-woven cloth (3) with surface- and bottom-layer non-woven cloth (2) on upper and lower sides, wherein a part of the surface- and bottom-layer non-woven cloth (2) in the diaper peripheral envelope area (6) is coated with hot melt adhesive before wrapping and under a combined action of extrusion heat sealing of a peripheral envelope roller and adhesion of hot melt adhesive, enabling the ultra-thin non-woven cloth (3) in the diaper peripheral sealing area (6) and the surface- and bottom-layer non-woven cloth (2) of the diaper to form a new adhesion area (4) and be integrally bonded. The method is a diaper manufacturing method that follows industry development and saves natural resources, and meets a requirement of using the high molecule water absorption material at the high proportion to manufacture the light and thin diaper cotton core body (1).Linvention concerne un procédé de traitement pour accroître la résistance au décollage dune enveloppe périphérique dune couche, qui comprend : laddition dune matière dabsorption deau de masse moléculaire élevée dans des fibres de pâte de bois à une proportion élevée, et lenveloppement des fibres de pâte de bois avec un tissu non tissé ultramince (3) pour préparer un corps de noyau de coton de couche (1), quatre côtés du tissu non tissé ultramince (3) sétendant dans une zone denveloppe périphér
