Abstract (en)
[origin: EP1818451A1] Wrapping paper comprises discrete islands surrounded by a network structure, where the islands have a lower fiber content and thus a lower density than the network structure. Independent claims are also included for: (1) paper bag for transporting bulk goods, with walls made of wrapping paper as above; (2) producing wrapping paper by dewatering pulp on a sheet former wire comprising a permeable support with a pattern of discrete islands of covering material surrounded by a network structure, where the islands have a lower permeability than the network structure.
