Embodiment 1

[0117] The following experiments were performed to demonstrate certain teachings of the present disclosure. In this example, commercially available low ignition propensity (LIP) cigarette papers were compared to wrappers made according to the present disclosure. Commercially available packaging materials are treated uniformly over their entire surface with citrate. The tape of the ignition reducing composition is then applied to the packaging material. In contrast, a packaging material is constructed such that the combustion promoter therein is applied only between the ignition reducing strips. The reduced ignition zone is formed by applying alginate to the packaging material.

[0118] The commercially available paper had a permeability of 60CU and was treated with 0.8% mixed citrate. Base paper includes relatively consistent amounts of fiber and filler (calcium carbonate).

[0119] In contrast, tapes of samples made according to the present disclosure were applied to area...

Embodiment 2

[0129]Additional packaging materials were constructed and tested according to some of the experiments described in Example 1 above. In this example, Example 5 below treated its entire surface area with potassium citrate. The tape of the ignition reducing composition is then applied to the packaging material. The tape is made from an alginate composition. Paper packaging materials are made from a mixture of softwood fibers, hardwood fibers and fillers.

[0130] Sample 6 below has no combustion promoter disposed in the reduced ignition zone. In addition, the packaging material includes untreated areas before and after each reduced ignition zone. The untreated area does not have any combustion promoter and has a width of 0.25 mm.

[0131] Packaging material is used to produce cigarettes. Standard American blends are used as cigarette fillers. Cigarettes were constructed such that Sample 5 and Sample 6 had approximately the same ASTM ratio and FASE ratio.

[0132] To obtain...

Embodiment 3

[0138] Additional packaging materials were constructed and tested. Sample 7 was made similar to Sample 5 in Example 2. Sample 8 was made similar to Sample 6 in Example 2. However, Sample 8 had a gap width of 2 mm in the untreated area.

[0139] Sample 9 was made according to the present disclosure and included a "dual tone" citrate treatment. In sample 9, the entire packaging material was first treated with 0.3% by weight sodium citrate. An additional 0.8% by weight of potassium citrate was then applied between the lower ignition zones. In addition, an untreated area or a barrier area having a gap width of 2 mm was formed.

[0140] In this example, the wrapper was constructed with the same band diffusivity at 23° C. using a wrapper with a lower permeability. The following result is obtained.

[0141]

[0142] As shown above, Sample 8 and Sample 9 have significantly better ASTM ratios at the same band diffusivity. Surprisingly, Sample 9 has a better ASTM Ratio and FAS...

Abstract

A wrapper for smoking articles having reduced ignition propensity properties is disclosed. The packaging material includes discrete areas treated with the ignition reducing composition. According to the present disclosure, the amount of combustion enhancer is controlled through the surface of the packaging material.

Description

[0001] Cross References to Related Applications [0002] This application is based on and claims priority to U.S. Patent Application Serial No. 61 / 783,632, filed March 14, 2013, and U.S. Patent Application Serial No. 61 / 712,621, filed October 11, 2012, both The entire content of the author is incorporated herein by reference. Background technique [0003] The tobacco industry is focusing on producing cigarettes with wrappers that reduce the propensity of the smoking article to ignite or reduce the tendency of the smoking article to ignite and the surfaces that come into contact with the lit smoking article. Fires caused by burning cigarettes in contact with flammable materials have been reported. There is legitimate concern in the industry about the trend to reduce exposure of cigarettes or other smoking products to ignition of surfaces and materials used in furniture, bedding, etc. [0004] Accordingly, a desirable feature of a smoking article, particularly a cigarette, is ...
