Last year, after the introduction, we should all know that a packaging factory has many kinds of materials to choose from. Of course, the materials used to customize gift hardcover boxes are cheap, expensive, high-quality and cost-effective. Then you may only know that there will be such different materials in the color hardcover box factory, but there is no difference I don't know. Even if the inner material is of the same variety, its quality can be divided into 369 grades. For example, today's protagonist, grey board

When it comes to grey board, you may think that it is not related to color hardcover box factory, because you have the impression that many watch hardcover box manufacturers should use high-quality white cardboard, and their stiffness and hardness are not like soft and easy to deform grey board, but a grey board with high specification and thick thickness will not only be used by color hardcover box factory In fact, many times this kind of high-quality, high-thickness gray board, their hardness and stiffness will be infinitely close to the gray bottom white, gray bottom black, whiteboard and other internal materials, and the advantage of gray board is cheap, of course, high-quality gray board is certainly more expensive than low-grade gray board, but it will not rise to the level of whiteboard The interior materials are so high

However, some people will worry that if the gray board is used, the processing difficulty of the color hardcover box factory itself will become greater, and even affect the quality of the finished box. This discrimination should be more reassuring. It is precisely because of the improvement of the grade of the gray board, the printing capacity, the internal air retention, the drying after mounting, and the extrusion deformation will be correspondingly improved It has been improved. Most of the time, the situation you see in the gray board is that if you squeeze it hard, you will see that it is obviously flattened. This is because the inside of the gray board, due to the problems of transportation and storage, it will have air entering, and the low-quality gray board itself will not have high density, so the air entering situation is particularly serious. In this case, it is necessary to use custom-made gift essence Packing, it is really the world's largest slip, hot stamping off, lamination blistering after mounting, but also from the inside material blisters, which are very likely to occur

Today, from the perspective of color hardcover box factory, I would like to introduce some problems about Grey Board to you, just to let you have a deeper understanding of grey board, because grey board can also be divided into high quality and low quality. High quality grey board can achieve more high material effects close to grey bottom white, white board and so on, instead of giving people a sense of low-end weakness like ordinary grey board sleep
