  • Publication number: 20170211237
    Abstract: A paper including a fibrous substrate, a precoat layer including a binder and a mixture of platy filler(s) having a shape factor of at least 15 and of finer filler(s), the size of the particles of which is, for 80% by weight, less than 2 ?m (measured according to the ISO 13317-3 SediGraph method) and at least one covering layer applied to the precoat layer, the paper having a water vapour permeability of at most 150 g/m2/24 h and preferably of less than 100 g/m2/24 h, measured according to the ASTM F1249 standard under so-called tropical conditions of 38° C. and 90% relative humidity.

  • Publication number: 20170081061
    Abstract: A twisting paper substrate to be waxed for the production of an opaque waxed paper wrapping, wherein the paper substrate includes a fibrous base, at least one opacifying additive and at least one binder reducing penetration of wax in the fibrous base during the production of the waxed paper substrate by application of wax on the paper substrate, wherein the difference of opacity of the paper substrate before and after Cobb test according to the rizinus Cobb method on one side to be waxed of the paper substrate is most preferably less than or equal to 8 percent.
