Abstract
A water based glue stick composition includes adhesive and nanocrystalline cellulose. The composition is contained in a glue stick that can be used for planar joining of substrates to one another. The substrates can include paper and/or cardboard such as printer paper, photo paper and cardboard paper.
Claims16
A water based glue stick composition, the composition comprising:
- water in a range of 40-70 weight % based on the total weight of the glue stick composition;
- an adhesive selected from the group consisting of starch, starch derivatives, and a mixture thereof,
- wherein the adhesive is in a range of 15-35 weight % based on the total weight of the glue stick composition;
- and
- an additive of nanocrystalline cellulose mixed with the adhesive,
- wherein the nanocrystalline cellulose content is in the range 0.1-1.5 weight % based on the total weight of the composition,
- wherein the nanocrystalline cellulose in the composition has a particle length in the range of 40-160 nm, measured by atomic force microscopy, and
- wherein the composition is solidified.
