Abstract
The invention relates to a sheet obtained by a papermaking process and usable as a product that can be substituted for conventional products referred to as impregnated glass covering products. The sheet essentially contains cellulose fibers, non-cellulose fibers, a thermoplastic powder of specified grain size, and a binder. It is optionally covered with a layer of plasticizer for the thermoplastic powder. Its resistance to traction-delamination increases with grain size. It is applicable as a backing, in particular to floor or wall coverings.
