Precautions in the printing process of silver paper for packaging

1, laser film in the production process, due to static reasons, inevitably there will be black spots, dirty spots, in order to cover up these defects, but also reflect the laser effect, in the design of cigarette printing process, usually need to add 20% ~40% of white nets.

2. There are two kinds of PET film, 12μm PET film and 23μm BOPP film. In order to ensure the molding effect and the smoke speed, 12μm PET film is usually used.

3. In order to improve the glossiness of cigarette packs, a laser-coated paperboard with aluminized layers outwards is often used, ie a laser-laminated paper combined with a PET film and a paper sheet. However, when the aluminized layer is outward, it is easily scratched. Need to pay attention.

4. In the die-cutting, in order to prevent burrs from appearing, a pattern peak knife may 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 gluing line at the life should be 23.7mm, and the density of the viscose gluing line should be increased.
