Problems solved by technology

People often inadvertently discard their cigarettes, and more particularly the filters thereof, into the environment.
Such an adhesive is used for the plug wrap bond, and loses strength when flushed or discarded into the environment, thus reducing the amount of paper in the environment.

example 1

[0022] The slurry had the following composition:

1 Component % Solids Basis NaCMC.sup.1 33.52 guar gum 22.35 glycerin 5.03 wood pulp 39.11

[0023] The slurry was cast at a slit width of 26.5 mm and a casting speed of 50 ft / min. The plug wrap material had a yellow color, a smooth texture and good strength. The plug wrap material dispersed in water in about 10 minutes.

example 2

[0024] Example 2 was similar to Example 1 except additional wood pulp on a percent solids on a basis was used.

2 Component % Solids Basis NaCMC 21.51 guar gum 14.34 glycerin 5.02 wood pulp 59.14

[0025] The slurry was cast at a slit width of 26.5 mm and a casting speed of 50 ft / min. The plug wrap material had a yellow color, a smooth texture and good strength. The plug wrap material dispersed in water in about 25 minutes.

example 3

[0026] Example 3 is similar to Examples 1 and 2 except that additional wood pulp on a percent solid basis was added.

3 Component % Solids Basis NaCMC 9.19 guar gum 6.13 glycerin 5.05 wood pulp 79.63

[0027] The slurry was cast at a slit width of 26.5 mm and a casting speed of 50 ft / min. The plug wrap material had a yellow color, a smooth texture and good strength. The plug wrap material dispersed in water in about 75 minutes with no stirring and about 8 minutes with slight stirring.

Abstract

An improved circumscribing plug wrap and tipping material are provided. The plug wrap and tipping material are a cast sheet which includes 20 to 70 percent by weight water dispersible cellulose material, 20 to 70 percent by weight of a water soluble film forming material and 0 to 10 percent by weight of a humectant. A smoking article (e.g., cigarette) using such plug wrap or tipping material or both is also provided.

Description

FIELD AND BACKGROUND OF THE INVENTION[0001] The present invention relates to plug wrap or tipping material, and particularly plug wrap or tipping material that is water dispersible.[0002] Increased environmental concerns have led to the desire of cigarette manufacturers to produce cigarettes, and particularly cigarette filters which degrade over time. People often inadvertently discard their cigarettes, and more particularly the filters thereof, into the environment. A proposed solution is provided in U.S. Pat. No. 5,453,144 to Kauffman et al., which relates to a water sensitive hot melt adhesive. Such an adhesive is used for the plug wrap bond, and loses strength when flushed or discarded into the environment, thus reducing the amount of paper in the environment.[0003] There, however, remains a need for a paper for plug wrap or tipping material or both that is environmentally friendly. Such a paper should be sufficiently strong to be used for its intended purpose, but will readily ...
