摘要： Making paper for corrugating medium includes forming a sheet of pulp material, partially drying the sheet of pulp material to provide a partially dried sheet, applying a crack-reducing agent to surfaces of the partially dried sheet, and providing a sheet of paper by drying the partially dried sheet after applying the crack-reducing agent. Forming a sheet of pulp material may include providing a pulp slurry to a headbox having a slice and carrying the pulp slurry that exits from the slice away from the headbox using, for example, a Fourdrinier. The Fourdrinier may also dry the sheet.

摘要： The present invention relates to a process for manufacturing a film comprising high amounts of microfibrillated cellulose (MFC), having haptic properties. According to the present invention, a wet web comprising MFC is formed, followed by addition of particles having an average diameter of at least 1 μm to the wet web, followed by dewatering and/or drying. The wet web may be formed for example by wet laid or cast forming methods. The particles may be added to the wet web for example by cast coating or spraying.

摘要： There is provided a method of producing a sheet comprising fibrillated cellulose, comprising the steps of: a) providing chemically modified cellulose fibres in which a chargeable moiety has been introduced and the C2-C3 bond has been broken in at least part of the D-glucose units, wherein the charge density measured according to SCAN-CM 65:02 is 150-1500 μeq/g; b) forming a fibre web by dewatering a slurry comprising the modified cellulose fibres; and c) adding a base to the fibre web so as to obtain the sheet comprising fibrillated cellulose.
