Claims14
Aqueous adhesive composition comprising:
- a) from 20% to 60% by weight of an amylomaltase-treated starch or an amylomaltase-treated maltodextrin, compared to a total weight of the aqueous adhesive composition, wherein the amylomaltase-treated starch is obtained from native starch comprising from 15% to 30% by weight of amylose and from 70% to 85% by weight of amylopectin, the weight percent being based on the total weight of the native starch;
- and
- b) ammonium zirconium carbonate.
Aqueous adhesive composition comprising:
- a) from 20% to 60% by weight of an amylomaltase-treated starch or an amylomaltase-treated maltodextrin, compared to a total weight of the aqueous adhesive composition;
- and
- b) ammonium zirconium carbonate, wherein the amylomaltase-treated maltodextrin is obtained from low DE maltodextrin having a Dextrose Equivalent (DE) lower than 10 (0 <DE <10).
Aqueous adhesive composition comprising:
- a) from 20% to 60% by weight of an amylomaltase-treated starch or an amylomaltase-treated maltodextrin, compared to a total weight of the aqueous adhesive composition;
- and
- b) ammonium zirconium carbonate, wherein the aqueous adhesive composition has a viscosity ranging from 100 mPa.s. to 5,000 mPa.s at 23° C.
