Problems solved by technology

[0002] As people's pace of life is accelerating, cigarettes have become a daily necessity for most people. Smokers are not only picky about the taste and taste of cigarettes, but also pay more and more attention to the outer packaging of cigarettes, especially For the high-end cigarette crowd, the quality of the outer packaging of the cigarette box is particularly important, especially the printing quality of the cigarette box. Most of them use offset printing technology to directly print on the substrate in layers to form various graphics, but often around the edges of the cigarette box, Or the bent part of the box cover will slowly crack and warp as the number of uses and time increase, or even fall off.

Abstract

The invention discloses an anti-cracking printing technology. According to the technology, an offset printing layer is protected and covered through a film coating process, so that not only is the offset printing layer prevented from cracking, upwarping and falling, but also the glossiness and a hand feel of a cigarette case body are greatly improved, and the experience feeling of a user is further improved; through a snow flack silk-screen technology, not only is an image-text visual effect of a cigarette case improved, but also an OPP high-gloss film can be further heat-sealed, adhered and coated on the surface of the case body, and an overall anti-cracking effect is improved; and through thick transparent laser transfer paper with the weight being 235 to 239g, the bending part of a lidof the cigarette case can be bent and buffered, so that the offset printing coating is prevented from cracking.

Description

technical field [0001] The invention relates to the technical field of cigarette packaging printing, in particular to an anti-cracking printing process. Background technique [0002] As people's pace of life is accelerating, cigarettes have become a daily necessity for most people. Smokers are not only picky about the taste and taste of cigarettes, but also pay more and more attention to the outer packaging of cigarettes, especially For the high-end cigarette crowd, the quality of the outer packaging of the cigarette box is particularly important, especially the printing quality of the cigarette box. Most of them use offset printing technology to directly print on the substrate in layers to form various graphics, but often around the edges of the cigarette box, Or as the number of uses and time increase at the bent part of the box cover, the offset printing layer will slowly crack and warp, or even fall off.
