<p>Packaging consisting of a bleached kraft paper, calendered or otherwise, corresponding to AFNOR standard NFQ 01005 and with a weight of 31 to 45 g per m<2>, employed by itself or adhesively backed with a paper, a polymer film, a cellulose or an aluminium foil, in partial or complete manner, whose cheese side is coated with a layer of paraffin wax or of wax containing polymer particles, the paper not being pretreated to obtain a wet strength (WS) so as to impart to the packaging a higher hydrophilicity in order to avoid any formation of condensation at the surface of the cheese, it being possible for the superior water vapour permeability resulting therefrom to be regulated by increasing the proportion of paraffin wax or of wax forming the cheese-adjoining layer and/or by increasing the quantity by weight of polymer particles introduced into the paraffin wax or wax layer on the cheese side, these also being responsible for the bonding of the paraffin wax or wax crystals onto the entire surface of the coating, in order to endow the packaging with a sufficient mechanical strength, especially wet strength.</p> |
