Embodiment Construction

[0058] figure 1 Examples of smoking articles to which the invention may be applied are shown. It is a cigarette comprising a roll of tobacco 20 enclosed in paper 10 and having a filter 30 .

[0059] figure 2 and image 3 The paper of a smoking article 1 according to the invention is shown.

[0060] The paper 10 used herein has an initial natural permeability (ie, prior to any treatment) of between 10 Coresta and about 200 Coresta, preferably about 10 to 80 Coresta, more preferably from 60 to 80 Coresta. It may be any commercially available paper used in smoking articles.

[0061] In order to form this paper 10 into a LIP paper, it is treated to form a series of regions 11 having low flame retardancy properties (LIP regions).

[0062] In order to do this, a coating formulation 13 is applied to the paper during a first step, which formulation is suitable for reducing porosity by at least partially blocking all or part of the porosity. Here, formulation 13 is preferably ap...

Abstract

The invention relates to a paper (10) for an article to be smoked (1), in particular for a cigarette, comprising zones treated (11) with a coating formulation (13) suitable for reducing the incendiary potential of said treated zone, in which the formulation (13) comprises cellulose nanoparticles having a median size (d50) less than or equal to five micrometres.

Description

technical field [0001] The present invention relates to a paper for smoking articles with low flame retardancy. Background technique [0002] Typically, cigarette paper intended for the production of industrial cigarettes is made from cellulose fibers (from wood fibers and / or plant textile fibers to which calcium carbonate is added to the fiber suspension like conventional pigments). [0003] Combustion retarding or accelerating salts are usually applied over the entire surface during manufacture to gain control over certain combustion parameters of the formed cigarette. These salts are usually sodium salts, potassium salts, magnesium salts and the like. These salts also impart improved combustibility to the cigarette. [0004] Current standards require cigarette manufacturers to comply with tar, nicotine, and carbon monoxide (CO) levels per cigarette below given thresholds. For example, European regulations require thresholds of 10 mg tar per cigarette, 1 mg nicotine per...
