Abstract (en)
A cloth-like material (20) formed from woven plastic fibers includes a surface region (30) of bonded together fibers. The region adds stiffness to the material thereby improving its utility in, for example, self-standing handles for large plastic bags. In one embodiment, the surface region is formed by pressing a hot iron against a surface of the material. The plastic fibers partially melt, and a slight depression is formed in the material having side and bottom walls formed from fused material from fibers adjoining the depression walls. The stiffened material can be attached as a stiffening rib to the surface of a flexible sheet, e.g., a sheet also formed from woven plastic fibers. In another embodiment, the surface region is formed by means of a rib of hardened, fused plastic. <IMAGE>
