Abstract:
PCT No. PCT/GB92/01685 Sec. 371 Date Jul. 21, 1993 Sec. 102(e) Date Jul. 21, 1993 PCT Filed Sep. 14, 1992 PCT Pub. No. WO93/06301 PCT Pub. Date Apr. 1, 1993.A package comprising a sealed container containing a roll of wall covering material which comprises a hydrophilic substrate layer, a pressure sensitive adhesive layer on one surface and, on the other surface, a decorative layer, usually including a layer of PVC or other plastics material. The wallcovering material is preferably self-wound on a roll. The moisture content of the wallcovering material is controlled in the package so as to provide a desired area of the product which falls between the area of the product where it is soaked in water under predetermined conditions and the area of the product when it is preconditioned under relatively dry, predetermined conditions. The moisture content is generally above the equilibrium content under normal ambient conditions so that any problems caused by expansion of the product in use under humid conditions, such as bubbling and raising of the edges of the material at seams, are minimised. In a process for producing the product the moisture content is monitored during the process, usually downstream from a drying stage, for instance the drying stage following application of an aqueous adhesive.
