[China Packaging Network News] In China, one of the performance of high-end cigarettes is reflected in the packaging of cigarettes. We will analyze the current state of the domestic cigarette pack printing process, and explain some of the details of the actual manufacturing process.
At present, in the cigarette pack printing, the commonly used process is as follows: When the low-grade cigarette packs are adjusted to middle-advanced grades, the printed sheets will be turned from ordinary fibers to non-receptive composite sheets individually.

There are two types of composite paper for cigarette packaging: aluminum foil composite paper (aluminum foil combined with cardboard), bright film (laser film) composite paper (bright film, laser film and glass cardboard composite). When printing on laser card paper, UV ink is often used to increase the ink adhesion.
Here are some things to note in laser jam printing:
Laser film in the production process, because of static causes, inevitably there will be spots, dirty spots, in order to cover up these shortcomings, but also reflect the laser effect, in the design of cigarette pack printing process, usually need to add 20% to 40% White net.
The laser film has 12 μm PET film and 23 μm BOPP film. In order to ensure the molding effect and the smoke speed, a 12 μm PET film is usually used.
In order to improve the gloss of cigarette packs, laser-coated paper with aluminum-plated outer layers is commonly used, ie, laser-laminated paper combined with PET film and paper. However, when the aluminized layer is facing outward, it is easily scratched. This must be done during printing. note.
When die-cutting, in order to avoid burrs, mold tip cutters can be used. Because PET film and paper are not bonded together, delamination often occurs during die cutting. Therefore, before the official production, it is necessary to carry out a small batch of packages on the package machine.
In order to ensure the viscose effect, the height of the viscose glue line at the life of the applicator should be 23.7mm, and the density of the viscose glue line should be increased at the same time.
