A textured film is provided which comprises nanocellulose. At least a first surface of the film comprises a patterned, textured surface formed by repeating protruding regions and at least one non-protruding region arranged between said protruding regions. A particular height difference between the protruding and non-protruding regions can give liquid repellent properties. Methods for making the textured film are also provided.

The invention refers to a method to produce a packaging material comprising the steps of; treating at least one surface of a paperboard substrate with a binder and with a metal salt, printing at least a part of said treated surface with ink, and applying at least one polymer layer on said printed surface. The packaging material produced in accordance with the invention shows good printability and simultaneously good adhesion of the applied polymer layer.

A surface treatment composition for paper, board or other fibrous webs. The composition of the invention comprises particles which comprise an active material and a supporting material. The active material comprises a salt of a multivalent metal, such as a divalent or trivalent metal. In accordance with the invention, the supporting material is adapted to release the active material from the particles when subjected to heat and/or pressure and/or a change in pH. Consequently, the active material's adverse effects on the rheology of the composition are avoided while its desired effects on the surface characteristics are retained or enhanced.

A method for printing a wet web material comprising microfibrillated cellulose, wherein said method comprises the steps of providing an aqueous suspension comprising microfibrillated cellulose; applying said aqueous suspension to a substrate, thus forming a wet web having a moisture content in the range of 5 to 70 weight-%; wherein the method further comprises the step of treating said wet web by heating at least one well-defined portion thereof, whereby the web is provided with a print at the at least one heated portion.

Printing paper without ink

The invention relates to a surface treatment composition for paper, board or other fibrous webs. The composition of the invention comprises particles which comprise an active material and a supporting material. The active material comprises a salt or a multivalent metal, such as a divalent or trivalent metal. In accordance with the invention, the supporting material is adapted to release the active material from the particles when subjected to heat and/or pressure and/or a change in pH. Consequently, the active material's adverse effects on the rheology of the composition are avoided while its desired effects on the surface characteristics are retained or enhanced.

The present invention relates to a method for manufacturing a polymer product with super- or highly hydrophobic characteristics, preferably in the form of a film. Also methods for the manufacturing of a laminate and a polymer coated paper or board product, respectively, both having said characteristics, are disclosed. The present invention also relates to products obtainable by said methods and uses thereof.

The invention relates to a method and an apparatus for jointing members made of plastic-coated paper or board. In accordance with the invention, the sealable members are retained in position with clamps and sealing is performed with a laser sealing means moving along the sealing line, a means for opening the seal point pressing the members apart to continue keeping the seal point open, a laser beam being directed to the open seal point for melting the coating plastic and a means for closing the seal pressing finally the members against each other, the plastic jointing the members when solidified. The method is applicable to lateral sealing of bag or container packages formed of blanks, among other things.
