Packaging grey board | Grayboard in high-end packaging

The gray board may seem to have nothing to do with the color hardcover box factory, because in everyone's impression, the materials used by many watch hardcover box manufacturers should be high-quality white cardboard, and their stiffness and hardness are not as soft as soft. , and easily deformed gray board, but a gray board with a relatively high specification and a thicker thickness will not only be favored by color hardcover box manufacturers, but also by necklace hardcover box manufacturers. In fact, many times this kind of high quality, high Thick gray boards, their stiffness and stiffness will be infinitely close to the inner materials of gray-on-white, gray-on-black, and whiteboard paper, and gray boards have the advantage of being cheap. Of course, high-quality gray boards must be lower than The grade of gray board is more expensive, but it will not rise as high as the internal materials such as white cardboard with gray background and white.
 

But some people will worry that if the gray board is used, the processing difficulty of the color hardcover box factory itself will become more difficult, or even affect the quality of the finished box. This discrimination should be more at ease. It is precisely because of the inner material. The level of the gray board has been improved, and its printing capacity, the air trapped inside, the drying after lamination, and the extrusion deformation will be improved accordingly. Many times, the situation that everyone sees on the gray board is that it is squeezed hard. , you will see that there is a relatively obvious flattening, which is officially because the interior of the gray board, due to the problem of transportation and storage, will have air entering, and the low-quality gray board itself does not have a high density, and the air will enter The situation is especially serious. In this case, if you use a custom-made gift hardcover box, it is really a big joke. The hot stamping falls off, and the film foams after mounting the paper, and the foam is from the inner material. , this is very likely to happen.
