A kind of inner lining film for manual easy opening tobacco packaging and processing method thereof

Abstract

The invention relates to the field of cigarette packaging, in particular to an inner lining film for manual and easy-to-open tobacco packaging and a processing method thereof. The inner lining film includes an aluminum-plastic composite film and a sealing sheet adhered to the aluminum-plastic composite film. The sealing sheet includes a sticking part and a flap extending from either end of the sticking part and integrally connected with the sticking part. The sealing piece passes through the sticking part. Adhered to the surface of the aluminum-plastic composite film, the wings are non-sticky and form an angle of 5-30° with the plane where the sticking part is located; the sealing sheet is a double-layer material structure. By designing a sealing sheet with a double-layer structure, the present invention forms a 5-30° warping angle between the wings and the plane where the sticking part is located through the heat shrinkage of the surface material of the sealing sheet. It has a good grip when the sealing sheet is opened once and repeatedly, and the package can be opened very easily.

Description

technical field [0001] The invention relates to the field of cigarette packaging, in particular to an inner lining film for manual and easy-to-open tobacco packaging and a processing method thereof. Background technique [0002] Baorun tobacco packaging has the function of preventing cigarettes from being affected by moisture and mildew from outside moisture.

However, the lower edge of the manually opened label is closer to the lower edge of the outer package of the cigarette pack. Although the opened flap has been treated with glue removal, it is still difficult to open when it is opened for the first time.

[0003] The patent PCT / EP2011 / 067164 discloses a package of cigarette products, which includes a package cover and a package body. The lower edge of the front wall of the package cover is extended with a tab, and the front wall of the tab and the package cover is provided with a weakened line, which is convenient After the tab is lifted, grasp the tab to open the packaging cover. However, because the tab is attached to the surface of the inner package, due to the long-term pressure of the top cover of the outer package, the tab is tightly attached to the inner box body, resulting in the protrusion of the tab. It is still difficult to open for the first time

[0004] Patent PCT / GB2019 / 053500 discloses a laminated material for packaging cigarettes, including an inner layer and an outer layer. The outer layer has a tab for lifting the outer layer area. The laminate is provided with a notch under the tab. The tab protrudes a certain distance from the edge of the notch, so that the user can lift the tab by inserting his finger into the notch to lift the outer layer and open the package. However, the design of the notch makes the cigarette package less airtight and easily affects the quality of the cigarette.
