Claims14
A sizing-adhesive for corrugating comprising:
- a mixture of two or more polymers,
- wherein at least one of the polymers, present in an amount of 30-95% by weight on a dry weight basis, is a water soluble polymer, wherein the water soluble polymer has a mean molecular weight (Mw) below 200,000 Daltons, wherein at least one of the polymers is selected from the group consisting of a polysaccharide, a polysaccharide derivative, and mixtures thereof, and wherein the adhesive has a Brookfield viscosity of between 100 and 3000 mPas when measured at 25° C., 100 rpm, and with a no. 4 spindle.
