    Impact of cigarette paper parameters on smoke yields of cigarettes with different circumferences

    MÜLLER P.; GLEINSER M.; BACHMANN S.; VOLGGER D.
    Papierfabrik Wattens GmbH & Co. KG, Wattens, Austria
    Cigarettes with reduced circumference are very popular in several markets. Over the last decade a significant growth rate has been observed worldwide. Changing the circumference has an influence on the physical properties of the unlit cigarette and ...

    Influence of storage conditions on smoke yields and optical appearance of cigarettes

    GLEINSER M.; BACHMANN S.; VOLGGER D.
    Papierfabrik Wattens GmbH & Co. KG, Wattens, Austria
    Chemical and physical changes of the cigarette paper can occur during the storage of cigarettes. These changes may have an influence on the smoke yields, the taste of a cigarette and also on the optical properties of the cigarette and the ash appearance ...

    Paper filters – the influence of different paper composition and paper properties on filtration efficiency and pressure drop

    GLEINSER M.; BACHMANN S.; VOLGGER D.
    Papierfabrik Wattens GmbH & Co. KG, Wattens, Austria
    Smoke yields, smoke composition and the taste of a cigarette can be modified by changing different parts of the cigarette, especially the different filter design. Cellulose acetate is currently the most common material for cigarette filters, but also ...

    Comparison of Full Length Burn testing according to ISO 12863 and the proposed alternative by NIST Laboratories, USA

    MAYR M.
    Papierfabrik Wattens GmbH & Co. KG / delfortgroup AG, Wattens, Austria
    NIST Laboratories USA proposed to use a thin stainless steel substrate plus one layer of filter paper instead of the 10 layers, as defined in ASTM E.2187-09 and ISO 12863 for measuring the percentage of Full Length Burn on Lower Ignition Propensity (LIP) ...

    The pore size distribution of naturally porous cigarette papers and its relation to air permeability and diffusion capacity – Part 1

    BACHMANN S.; GLEINSER M.; VOLGGER D.; EITZINGER B.
    delfortgroup AG, Papierfabrik Wattens GmbH & Co. KG, Wattens, Austria
    In the tobacco industry, it is well known that porosity is one of the most significant physical properties of cigarette paper. There are indirect and direct methods to characterize this parameter. Measurement of the diffusion capacity and air permeability ...

    The pore size distribution of naturally porous cigarette papers and its relation to air permeability and diffusion capacity – Part 2

    EITZINGER B.; GLEINSER M.; BACHMANN S.; VOLGGER D.
    delfortgroup AG, Papierfabrik Wattens GmbH & Co. KG, Wattens, Austria
    Regulations regarding the self-extinguishment of cigarettes and the upper limits on smoke yields have, in addition to air permeability, led to an appreciation of diffusion capacity as a further important parameter of cigarette paper. Air permeability and ...

    Impact of using a metal sheet as an “alternative substrate for ISO 12863” on SE performance

    MAYR M.; VIZEE H.
    Papierfabrik Wattens GmbH & Co KG / delfortgroup, Wattens, Austria
    The aim of this study was to demonstrate the impact on SE performance when using different material than filter paper as a possible substrate. NIST proposed to perform these tests on a thin metal sheet (0,2 mm) with one layer of filter paper. As the ISO ...
