Abstract
The adhesive compositions that include starch derivatives, plasticizers, optionally cellulose derivatives, and optionally other additives. By tailoring the composition and concentration of these components, hot melt adhesive compositions, hot melt pressure sensitive adhesive compositions, and pressure sensitive adhesives have been produced. Further, these adhesive compositions may be useful in articles including diapers, laminates, repositionable advertisements, and many more.
Claims19
A hot melt adhesive composition comprising a starch derivative;
- and a plasticizer in an amount of about 5% to about 60% by weight of the hot melt adhesive composition, wherein the adhesive is non-tacky at room temperature.
A pressure sensitive hot melt adhesive composition comprising a starch derivative;
- and a plasticizer in an amount of about 15% to about 75% by weight of the pressure sensitive hot melt adhesive.
A pressure sensitive adhesive composition comprising a starch derivative;
- a plasticizer in an amount of about 40% to about 90% by weight of the pressure sensitive adhesive composition.
A pressure sensitive adhesive composition comprising a starch derivative;
- and a plasticizer in an amount of about 5% to about 90% by weight of the hot melt adhesive composition and a cellulose derivative at a concentration of about 0.02% to about 65% by weight of the adhesive composition.
