1. In the production process of laser film, due to static electricity, black spots and dirty spots will inevitably appear. In order to cover up these defects and at the same time reflect the laser effect, when designing the cigarette pack printing process, it is usually necessary to add 20% ~ 40% white net.
2. There are two types of laser film: 12μm PET film and 23μm BOPP film. In order to ensure the molding effect and the speed of cigarette pack, 12μm PET film is usually used.
3. In order to improve the glossiness of cigarette packs, laser cardboard with aluminum coating facing outwards, that is, laser cardboard with PET film and paper combined, is often used, but when the aluminum coating facing outwards, it is easy to be scratched. Pay attention.
4. During die cutting, in order to prevent the occurrence of burrs, a die pattern peak knife can be used. Because PET film and paper are not firmly combined, delamination often occurs during die cutting. Therefore, before the official production, it is necessary to carry out small batches of cigarette pack test packages. In order to ensure the viscose effect, the height of the glue line at the paste should be 23.7mm, and the density of the glue line should be increased.
Bioplastic cutlery refers to disposable utensils, such as forks, knives, and spoons, that are made from biodegradable or compostable materials. Unlike traditional plastic cutlery, which is typically made from petroleum-based plastics that can take hundreds of years to decompose, bioplastic cutlery is designed to break down more quickly and harmlessly in the environment.
