Problems solved by technology

In the production of cigarettes, due to the use of pull wires, there will be problems that affect the quality of packaging, such as pull wires falling off, wrong mouths, deviations, and reverse pull wires.
At the same time, during the production process, adjusting the switch between special pull wire coils and changing the special pull wire will lead to increased work and labor.
In addition, consumers' pursuit of visual effects on packaging has further weakened the presence of pull cords for cigarettes

Embodiment 1

[0020] The manufacturing method of the packaging film for cigarettes with the function of invisible pull wire of the present invention comprises the following steps:

[0021] 1) Production of packaging film: according to the technical requirements of cigarette products, produce packaging film that meets the standards; the packaging film adopts biaxially stretched POPP packaging film.

[0022] 2) Set up parallel grooves: Process two parallel grooves on the packaging film according to the position of the wires in the cigarette package, and the grooves are processed by laser machining. The groove is parallel to the edge of the packaging film, and the edge of the packaging film refers to the film edge in the length direction of the packaging film.

[0023] The packaging film between the two grooves forms an invisible puller with a puller function. The distance between the outer groove of the two grooves and the edge of the packaging film is 30-80 mm. The width of the groove is 1...

Embodiment 2

[0025] This embodiment provides the packaging box for cigarettes packaged using the packaging film produced by the method of Embodiment 1, such as figure 1 with 2 As shown, the cigarette package includes a package body and a packaging film 1 covering the package body. The packaging film 1 is provided with two grooves 2 arranged in parallel, and the packaging film between the two grooves forms a Invisible pull cord with pull cord function3. After the packaging film 1 is packaged in the packaging box, the groove is placed on the inner surface of the packaging film 1 .

[0026] For the convenience of tearing the invisible backguy 3, a U-shaped opening guide cut is set at the overlapping junction of the packaging film, and the guide notch coincides with the outside of the invisible backguy 3 between the two grooves to facilitate opening.

[0027] The present invention saves the packing pull wire, and forms the self-contained invisible pull wire through the part between the groov...

Abstract

The invention discloses a manufacturing method of a packaging film with an invisible stay wire function for cigarette and a packaging box for cigarette. The packaging film meeting cigarette product process standards is produced, two grooves which are arranged parallel to each other are formed in the packaging film according to a stay wire position in cigarette packaging, and the packaging film between the two grooves forms the invisible stay wire with a wire drawing function. According to the manufacturing method of the packaging film with the invisible stay wire function for the cigarette and the packaging box for the cigarette, the production process is simple, the quality problems of broken stay wire, staggered joints, deviation, double stay wires and the like caused by using the stay wire are solved, the cigarette production cost can be further reduced, and the reputation of cigarette products is improved.

Description

Technical field: [0001] The invention relates to a method for manufacturing a packaging film for cigarettes with the function of invisible pull wires and a packaging box for cigarettes. Background technique: [0002] Traditional cigarette packaging will add a layer of transparent packaging film outside the paper cigarette label to play a certain role in sealing and moisture-proof. Pull wires for cigarettes are used to facilitate the opening of cigarette packaging boxes. Most of the cigarettes on the market that are wrapped with films use the pull wire technology. In the production of cigarettes, due to the use of pull wires, there will be problems that affect the quality of packaging, such as pull wires falling off, wrong mouths, deviations, and reverse pull wires. At the same time, in the production process, adjusting the switch between the special backguy coils and changing the special backguy will lead to increased labor. In addition, consumers' pursuit of visual effect...
