摘要： The present invention provides a method of forming a coating on a porous sheet, comprising the steps of: providing a porous sheet and a dispersion comprising at least one polyolefin; applying said dispersion on at least one surface of said sheet; and optionally, heating said sheet to a temperature above the melting temperature of said at least one polyolefin. Moreover, the present invention relates to methods for manufacturing single and two ply sacks and the use of at least one polyolefin as a water vapour barrier coating on a material suitable for a ply of a sack.
