Polysaccharide adhesives for multi-ply paper products |
摘要 |
An aqueous, light weight paper laminating adhesive comprising a continuous aqueous phase of from about 15 to 50% by weight of polysaccharide material dispersed in water, the continuous phase polysaccharide material having a zero-shear viscosity of greater than 0.07 Pa.s when measured at 26% (+/-1% solids) and a shear rate of 0.1s-1; a shear-thinning index of 0.90 to 1.1; and bleed time of greater than 15 seconds. Also disclosed is another adhesive composition, which is particularly useful in non-contact spay applications and comprises the continuous phase polysaccharide phase described above as well as a second component comprising a water swellable, insoluble polysaccharide particulate phase.
