Abstract
Described are compositions for use in paper products including a modified starch, paper products including a modified starch, and methods of making paper products, and the like. The compositions can include a pulp slurry and a modified starch and can include hardwood fibers, softwood fibers, non-wood fibers, or a combination thereof. Provided for are paper products, such as tissue paper, having a basis weight below 150 gsm. Also provided for are methods for making paper products that can include mixing a pulp slurry with an enzymatically modified starch derivative.
Claims18
A composition comprising a pulp slurry and a modified starch, wherein the modified starch has a cyclic structure and water solubility greater than 10 mg/mL when immersed at about 25° C., and wherein the pulp slurry comprises hardwood fibers, softwood fibers, non-wood fibers, or a combination thereof.
A paper product having a basis weight below 150 gsm, comprising:
- a blend of hardwood fibers and softwood fibers, wherein a total fiber content is at least 80 wt % of a total weight of the paper product;
- and
- a modified starch, wherein the modified starch is from about 0.02 wt % to about 10 wt % of the total weight of the paper product.
A method for making a paper product, comprising:
- mixing a pulp slurry with an enzymatically modified starch derivative, wherein the pulp slurry comprises a blend of hardwood fibers and softwood fibers.
