Abstract (en)

[origin: EP0786551A1] A process for manufacture of a web of material (1) entails producing a plastic layer (5, 6) on at least one side of a carrier (2) from a mixture of plastic material and granular soluble pieces, and afterwards dissolving out at least some of the pieces by a solvent against which the plastic is resistant while forming permeable channels. Plastic powder is prepared, mixed with the small soluble pieces and applied to the carrier. The plastic layer (5, 6) is formed from the mixture by heat and pressure treatment before dissolving at least some of the pieces.
