    摘要： A sidestream smoke removing device includes a housing having a smoking space defined therein, an article inserting part positioned on one end of the housing and having an open area through which a smoking article is inserted into the smoking space, and a sidestream smoke processing part positioned at a distance from an upstream end of the smoking article inserted into the smoking space and configured to process sidestream smoke produced from the smoking article. The sidestream smoke processing part includes a filter including a filter included of pressed activated carbon having a plurality of holes allowing the sidestream smoke to pass therethrough and a ventilation fan configured to allow the sidestream smoke to be discharged through the filter. The sidestream smoke removing device obtains superior functionality in terms of a sidestream smoke removal rate and deodorizing performance while maintaining a suitable flow rate therein.

    摘要： A sidestream smoke removing device includes a housing having a smoking space defined therein, an article inserting part positioned on one end of the housing and having an open area through which a smoking article is inserted into the smoking space, and a sidestream smoke processing part positioned at a distance from an upstream end of the smoking article inserted into the smoking space and configured to process sidestream smoke produced from the smoking article. The sidestream smoke processing part includes a plasma ion filter configured to generate plasma ions using a high voltage electrode and a ventilation fan configured to allow the sidestream smoke to be discharged through the plasma ion filter. The sidestream smoke removing device obtains superior effects in terms of a sidestream smoke removal rate and deodorizing performance without significantly reducing the flow rate after the application of the filter.

    摘要： Provided is a biodegradable film for cigarette packaging, the film including a first film layer applied such that one surface thereof faces a cigarette product, a third film layer applied such that one surface thereof is exposed to the outside, and a second film layer positioned between the first film layer and the third film layer. In the biodegradable film, the first film layer, the second film layer and the third film layer are each formed with different compositions, and at least one of the first film layer, the second film layer and the third film layer includes a biodegradable material. The biodegradable film has a biodegradation rate of 90% or more after 60 days, and has a heat shrink ratio of 4.0% or more.
