Discloses is a packaging paper for food having a grammage between 20 g/m.sup.2 and 40 g/m.sup.2, and having a filler content of less than 20 wt. % relative to the weight of the uncoated paper. On at least one side the packaging paper has a coating that contains a vegetable oil encapsulated in a polymer, and also talc and a binder. Both sides of the finished packaging paper have a Cobb 60 value of 14 g/m.sup.2 to 22 g/m.sup.2.

A coating structure for a sheet-like substrate, which includes lignocellulosic fibres is disclosed. The structure includes at least one pre-coat layer including at least 70 weight-% of a first styrene (meth)acrylate copolymer polymerised in the presence of a stabiliser, having a glass transition temperature Tg ≤20° C. preferably ≤10° C., ≤30 weight-% of inorganic platy mineral particles and 0.01-2 weight-% of at least one first thickener. The coating structure further includes a top coat layer including at least 50 weight-% of a second styrene (meth)acrylate copolymer polymerised in the presence of a stabiliser having a glass transition temperature Tg ≤20° C. preferably ≤10° C., ≤30 weight-% of inorganic mineral particles, 0.01-5 weight-% of at least one second thickener and 0.5-30 weight-% of an antiblocking agent. Further disclosed is a sheet-like product coated with the coating structure.

The invention relates to a method for producing a covering layer for elastic laminate comprising a) impregnating a carrier fabric, b) applying a surface coating comprising a crosslinker and a prepolymer that can be crosslinked via reactive end groups, c) crosslinking the crosslinkable prepolymer, and d) drying the elastic laminate covering layer. The papers obtainable in this manner are suitable for producing a laminate that, with the elastic outer face thereof, has a pleasant and appealing feel underfoot and good haptics.

The present disclosure describes methods of treating cellulosic materials with barrier coating compositions that allow for modifications of surfaces, including making such surfaces exhibit barrier functions such as oil and grease resistance, water resistance and the like. The methods as disclosed provide combining at least one saccharide fatty acid ester (SFAE) with polymers and applying such combinations on substrates including cellulose-based materials. Compositions comprising combinations of SFAE and polymers are also disclosed, including the use of such compositions to reduce blocking effects of said polymers without affecting the barrier performance or folding of articles of manufacture coated with said compositions. In addition, blocking ratings data for SFAE-polymer compositions may be used to identify conditions under which adhesive properties may be exploited to produce compositions that allow for effective heat sealing of articles of manufacture.
