Abstract

Included are polymer compositions including a polymer and about 0.1% to 25% by weight of a cellulose additive. The polymer composition is in the form of a film and the cellulose additive may be a cellulose ester such as cellulose acetate butyrate.

Claims (12)

1. A polymer composition for an absorbent article consisting of a polymer and about 0.1% to 25% by weight of a cellulose ester,

wherein the polymer is selected from the group consisting of polyolefins, polyurethanes, polyurethaneureas, nylons, polyesters, and mixtures thereof, and

wherein the cellulose ester is selected from the group consisting of a cellulose propionate, cellulose acetate phthalate, and mixtures thereof.

2. An absorbent article which consists of the polymer composition of claim 1 .

3. The polymer composition of claim 1 , wherein the polymer is selected from the group consisting of polyolefins, nylons, polyesters and mixtures thereof.

4. The polymer composition of claim 3 , wherein the polymer is selected from the group consisting of polyolefins, nylons and mixtures thereof.

5. The absorbent article of claim 2 , wherein the polymer is selected from the group consisting of polyolefins, nylons, polyesters and mixtures thereof.

6. The absorbent article of claim 5 , wherein the polymer is selected from the group consisting of polyolefins, nylons and mixtures thereof.

7. The absorbent article of claim 2 , wherein the absorbent article is a hygiene article.

8. The absorbent article of claim 7 , wherein the hygiene article is diapers, training pants, adult incontinence articles or feminine hygiene articles.

9. A method for preparing a film with reduced tack and maintained or enhanced gluing properties comprising the step of forming the polymer composition of claim 1 into said film.

10. The method of claim 9 , wherein said forming step is selected from the group consisting of casting and extruding.
