Title:
【発明の名称】マルトデキストランをベースとする接着剤
Document Type and Number:
Japanese Patent JP2002515925
Kind Code:
A
Abstract:
The present invention is directed to remoistenable and non-remoistenable adhesives which contain at least about 50 wt % of a maltodextrin syrup having a reducing sugar content of about 5-19 dextrose equivalent and solids content of about 60-80 % water, and an effective amount of other conventional adhesive additives. When the adhesive is a remoistenable adhesive, a chemically derivatized starch having an amylose content of 40 % or less and a D.S. of about 0.01 to less than about 0.50 is used. A preferred remoistenable adhesive also contains polyvinyl acetate and/or ethylene vinyl acetate in an amount from about 15-90 wt. % The maltodextrin syrup is prepared from a converted or a non-converted, chemically derivatized or underivatized granular starch, by a high solids, single phase enzyme conversion process. When derivatized, the maltodextrin has (i) substituents in an amount sufficient to provide a degree of substitution between greater than about 0.01 and less than about 0.50. Some of the chemically-derivatized maltodextrins have a polymodal molecular weight distribution with one peak between about 630-1600 daltons and at least one other peak between about 1600-2,500,000 daltons.
