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 manufacturing method of a paper, board or the like having a grammage in a range of 125-600 g/m.sup.2, preferably 150-210 g/m.sup.2, including adding a paper sizing agent including maleated vegetable oil and an alkenyl succinic anhydride (ASA) to a fibre stock including at least 80 weight-% of recycled fibre material and having calcium concentration of at least 500 mg/l, expressed as CaO.
