Abstract

A composition including a first fiber derived from a first natural source, and a second fiber derived from a fruit, the second fiber being substantially free of surface active components. Surface active components may include oils, fatty acids, or other aliphatic and aromatic moieties that compromise edge wick performance. A process of manufacturing a paperboard product may include removing surface active components from fruit fiber to be included in manufacturing paper products to obtain a paper product with improved edge wicking properties.

First claim

The invention claimed is:

1. A paperboard material, comprising:
a first fiber derived from a wood source; and
a second fiber derived from a fruit source, the second fiber being substantially free of surface active components,
wherein the paperboard material has reduced edge wicking properties relative to a paperboard material comprising a second fiber that is not being substantially free of surface active components.

2. The paperboard material of claim 1 , wherein the paperboard material absorbs water at a Cobb test rate of less than about 60 g/m 2 .

3. The paperboard material of claim 1 , wherein the first fiber is selected from the group consisting of: a hardwood fiber, a softwood fiber, and combinations thereof.

4. The paperboard material of claim 1 , wherein the second fiber is a citrus fiber.

5. The paperboard material of claim 4 , wherein the citrus fiber is an orange, sweet orange, clementine, kumquat, lime, leeche lime, satsuma, mandarin, tangerine, citron, pomelo, lemon, rough lemon, grapefruit, tangerine, or tangelo fiber.

6. The paperboard material of claim 4 , wherein the citrus fiber is derived from the group consisting of: albedo, endocarp, pulp, and combinations thereof.

7. The paperboard material of claim 4 , wherein the material comprises at least 20% of the second fiber.

8. The paperboard material of claim 7 , wherein the material comprises at least 30% of the second fiber.

9. The paperboard material of claim 1 , wherein the surface active components include oils, fatty acids, or other aliphatic and aromatic moieties.
