Abstract: Adhesive products such as label stock, labels, tapes and the like having a facestock, an adhesive layer and a removable, fibrous backing are described. The backing is provided with integral embrittled zones which crack when the adhesive product is flexed and offer gripping points for removal of the backing. The embrittled zones contain brittle, film-forming organic polymer suffused among the fibers. The presence of the polymer in the embrittled zone helps to enhance the brittleness of the zones and to reduce the transfer of residual chemical embrittling agent from embrittled zones of the backing to portions of the facestock brought into contact therewith when the adhesive product is stacked or rolled. Embrittled zones are preferably formed by applying a thickened acidic solution comprising a polymer emulsion to the backing of the adhesive product and then curing and drying the solution by heating.

Abstract: A premoistened wiper having high initial wet strength in a wetting liquid, and lower wet strength when immersed in substantially neutral water to allow for flushability. The wiper includes a nonwoven web of fibrous material which is bonded together by a polymeric adhesive binder, with the bonded web being moistened until the time of use by a wetting liquid having an acid pH level which is safe for external use on the human body. The binder is composed of a material which is highly adhesive in an acid pH liquid to bind the fibers of the web together, and which is further resistant to weakening over the relatively long periods of shelf life of the wiper. However, the binder loses its binding strength in substantially neutral or alkaline flush water to allow for flushability. The bonded wiper is maintained with wetting liquid thereon within a moisture sealed container until the time of use, and readily loses strength and disintegrates when disposed of in the substantially neutral water of a sewer system.
