Corrugating adhesive, method for preparing corrugating adhesive, and corrugated board

摘要

Disclosed is a method for the preparation of a corrugating adhesive. The method includes the steps of extracting hemicellulose from a hemicellulose-containing plant source, separating the hemicellulose in a soluble phase from the insoluble portion of the hemicellulose-containing plant source, and mixing the hemicellulose-rich phase with starch to form an adhesive composition. The adhesive composition of the invention exhibits superior shear stability properties as compared with prior art adhesive compositions that incorporate pasted starches, and exhibits superior green tack as compared with prior art hemicellulose-based adhesives. Also disclosed are a corrugated board and a method for preparing same.
