A method for producing cellulose-fibre-based drinking straws and a drinking straw. The method comprises: providing a cellulose material, producing at least one aqueous suspension comprising the cellulose material and adding additives to the suspension, homogenizing the aqueous suspension and pre-drying to obtain at least one water-containing non-woven web having a first side and a second side, drying the water-containing non-woven web in a plurality of drying steps to form at least one paper web having a first side and a second side, further processing the paper web or a plurality of paper webs to form a cellulose-fibre-based drinking straw.

At least the first side of the non-woven web is compressed with a line load of 80 kN/m to 500 kN/m before, during or after one of the drying steps and before the further processing to form a cellulose-fibre-based drinking straw.

A softener composition for use in the manufacture of paper includes a softener and an acidic material, wherein the softener composition has a relative acidity (RA) value of more than 0.05.

A repulpable moisture resistant protein box having a composite structure with a fluted medium, a top backing board secured to one side of the fluted medium and a bottom backing board secured to the other side of the fluted medium. The backing boards are impregnated with a hydrogenated triglyceride on the wire side and the fluted medium is also impregnated with a hydrogenated triglyceride. The backing boards each have an outer felt side surface coated with styrene acrylic co-polymer. The protein boxes have a higher compression, moisture resistance and are recyclable.

A film is made from a wet laid product containing cellulose fibers and cellulose ester fibers and a plasticizer. The film can be made by heat pressing the wet laid sheet to form a film having a continuous phase of cellulose ester resin and a discontinuous phase of cellulose fibers.

After cellulose fibers and cellulose ester fibers are co-refined, they are fed to a blend tank continuously feeds a wet laid process. The composition in the blend tank includes co-refined cellulose fibers and cellulose ester fibers and one or more additives, and the cellulose ester fibers have a denier per filament (DPF) of less than 3, a cut length of less than 6 mm, crimped, or non-round with a DPF of less than 3.
