Problems solved by technology

Among them, the disadvantages of double gold wires are high cost (equipment needs to be modified, low production efficiency, and high consumables). If the direction of pulling the gold wires is not controlled well, there will still be some cases where the packaging film is not easy to fall off, which cannot completely solve the problem of opening the film. The problem of packaging; and the practice of manually making cutouts and sticking self-adhesive labels, the cost is high, the production efficiency is low, and the quality is not easy to control

Embodiment 1

[0081] The film used in the high-precision laser minimally invasive functional film in this embodiment is BOPP, which is divided into three layers of upper layer, middle layer and lower layer, with a total thickness of 18 μm, a laser frequency of 20%, a tangent depth of 8 μm, and a tangent length of 10 mm (10mm on both sides of the gold wire);

[0082] The manufacturing method of the above-mentioned high-precision laser minimally invasive BOPP cigarette film is as follows:

[0083] (1) Film roll unwinding

[0084] Place the BOPP cigarette film cut according to the required width on the unwinding position of the equipment;

[0085] (2) Surface treatment

[0086] Corona treatment is carried out on the coding area of ​​the film. If the surface tension of the film itself is greater than 37 dynes and the adhesion to the ink is sufficient, it may be considered not to use corona treatment;

[0087] (3) Gold pull wire

[0088] Press the gold wire on the designated position of the ...

Embodiment 2

[0098] The film used in the high-precision laser minimally invasive functional film in this embodiment is BOPP, which is divided into three layers: upper layer, middle layer and lower layer. (15mm on both sides of the gold wire);

[0099] The manufacturing method of the above-mentioned high-precision laser minimally invasive BOPP cigarette film is as follows:

[0100] (1) Film roll unwinding

[0101] Place the BOPP cigarette film cut according to the required width on the unwinding position of the equipment;

[0102] (2) Surface treatment

[0103] Corona treatment is carried out on the coding area of ​​the film. If the surface tension of the film itself is greater than 37 dynes and the adhesion to the ink is sufficient, it may be considered not to use corona treatment;

[0104] (3) Gold pull wire

[0105] Press the gold wire on the designated position of the film, this step is better implemented on the customer's cigarette charter machine;

[0106] (4) Online coding

Abstract

The invention provides a high-precision laser minimally invasive functional film. The high-precision laser minimally invasive functional film comprises a film body, a gold pull wire is arranged on the surface of the film body; the film body is provided with an indentation, the indentation is located on one side or two sides of the gold pull line, and one end of the indentation extends to the gold pull line. According to the method, on the premise that the sealing performance of film packaging is guaranteed, laser is used for forming shear marks on the surface layer of the film, but the surface layer of the film is not cut through, meanwhile, other appearance defects caused by heat such as whitening, yellowing and edge curling are not caused to the film except the shear marks, and in order to solve the problem of terminal computer application, the method has good application prospects. A mode of firstly spraying codes (online spraying positioning blocks) and then performing laser cutting is used on the film, and the cigarette film with the characteristics of the positioning blocks and laser cuts is rolled into a roll, so that the production efficiency problem of terminal application is solved. The method thoroughly solves the problem that the film is not easy to fall off after the golden stay wire is torn off in the special-shaped packaging of the tobacco, on one hand, the cost is not increased greatly, and on the other hand, the original product design concept is guaranteed without causing visual influence.

Description

technical field [0001] The invention relates to the technical field of tobacco, in particular to a high-precision laser minimally invasive functional film and a manufacturing method thereof. Background technique [0002] After more than 40 years of development of BOPP cigarette film, the packaging method is changing with each passing day. Traditional cigarettes, especially small packets, have the mouthpiece set on the top of the small box. Generally, the gold wire can be pulled off and the packaging at the mouthpiece can be directly removed. Film peels off easily. And some special-shaped cigarettes, such as opening from the side, often when pulling the gold wire, if the direction is not controlled well, it will cause a large area of ​​film to wrap the cigarette case and cannot be opened. [0003] At present, there are two main methods to solve this problem in the tobacco industry. One is to use parallel double gold wires, such as the pilot cigarette of Furongwang of China T...
