Description

Technical Field

[0001] This application relates to the technical field of cigarette packaging equipment, and in particular to a frame paper packaging mechanism for cigarette packs. Background Technology

[0002] As market demands for cigarette product quality continue to rise, maintaining the quality parameters of cigarette products, such as taste, aroma, and moisture content, is particularly important during storage, transportation, and use.

[0003] In related technologies, cigarette packaging mainly uses aluminum foil as the inner lining material, and achieves sealing through heat sealing or mechanical folding. Although aluminum foil can block some oxygen and moisture, its heat-sealed layer is prone to tiny gaps due to friction or high-temperature environments during long-term storage and transportation, causing the cigarette aroma to leak out or become damp. When aluminum foil is combined with matching sealing processes (such as heat shrink film), high-temperature treatment (such as a 145℃ heat shrink machine) is required, which is not only energy-intensive but may also damage the breathable filter rod structure of the cigarette filter tip, affecting the stability of the smoking flavor.

[0004] To address the aforementioned technologies and ensure high sealing performance of cigarette packaging while preserving the aroma and moisture of the cigarettes, a pre-cut frame paper is used to initially fix the cigarette packs. Then, a heat-sealing film with a self-adhesive seal is used for preliminary packaging of the frame cigarette pack, thus iterating on the aluminum foil packaging method. Therefore, a frame paper packaging mechanism for cigarette packs is needed to wrap the pre-cut frame paper around the outside of the cigarette pack, thereby initially fixing the cigarette pack. Utility Model Content
