A storage/dispensing assembly, e.g., a roll or stack, of non woven pressure sensitive adhesive tape comprising one or more multilayer sheets of pressure sensitive adhesive tape arranged such that the adhesive layer in the assembly of an overlying non woven pressure sensitive adhesive tape is in direct contact with the underlying nonwoven backing layer of non woven pressure sensitive adhesive tape. The non woven backing layer is formed at least in part of fibers having a denier of greater than 15 so as to decrease the level of fibers disengagement when an overlying nonwoven pressure sensitive adhesive tape is removed from the assembly.
L'ensemble concerne un ensemble stockage/distribution, p. ex. un rouleau ou une pile, de ruban adhésif autocollant non tissé comportant une ou plusieurs feuilles multicouches de ruban adhésif autocollant placée(s) de telle sorte que la couche adhésive de l'ensemble constitué par un ruban adhésif autocollant non tissé sus-jacent est en contact direct avec la couche de support non tissée sous-jacente du ruban adhésif autocollant non tissé. La couche de support non tissée est formée au moins en partie de fibres présentant un denier supérieur à 15, de façon à réduire le degré de dégagement de fibres lorsqu'un ruban adhésif autocollant non tissé sus-jacent est enlevé de l'ensemble.
