The packaging box has to go through many technological processes from design to printing. In a relatively humid area, before the packaging box is produced, the color of the surface of the box will be slightly yellow due to the high humidity in the factory, and there are other packaging boxes made of special materials. How to better solve such problems? Some protective measures should be taken from the production side to effectively reduce the quality problems after the packaging box design and printing to the factory.
In the process of actual production and processing, there are several common quality problems in the laminating process: (1) The phenomenon of product curling angle. Generally, the reason for this is that there are too many sheets to be pasted, or the paper is too thin and the glue is not uniform, so that the glue on the edge of the cardboard has dried and cannot be stuck. Therefore, it is more appropriate to squeeze about 20 sheets.
(2) The humidity of the product is high, especially for the flat sticking of the gold card. The main reason is that gold cardboard has poor water penetration and loss ability, while ordinary flat adhesive has high water content, so it is usually solved by quick-drying adhesive or by placing the product in the sun to dry. (3) If the mounted tile or flat-mounted product is placed in an environment with high air humidity, it will turn yellow for a long time.
Mainly because some manufacturers use water glass glue or starch glue with high alkalinity. Therefore, in order to ensure the quality of the product, we should choose flat stickers and corrugated adhesives with better quality. (4) The phenomenon of delamination of packaging products is mainly because the strength of the adhesive is not enough.
If the products of regular manufacturers are selected, this situation will not occur, which can not only ensure the strength, reduce humidity, increase stiffness, but also improve the packaging. product quality and grade. Hot stamping, also known as hot stamping, is a process of heating a metal printing plate, applying foil, and embossing golden text or patterns on the printed matter.
The bronzing process pattern is clear and beautiful, the color is bright and eye-catching, wear-resistant and weather-resistant. It can play the role of finishing touch and highlighting the design theme, especially for trademarks and registered names, the effect is more significant. Of course, in order to meet the standard of bronzing process, there are also high requirements for materials.
There are many kinds of bronzing paper materials, including gold, silver, laser gold, laser silver, black, green, etc. The effect of post-processing. At present, the common embossing process in the production of gift packaging boxes is to use modern engraving technology to make female and male molds that cooperate with each other.
The embossing and concave process of hot stamping boxes is completed at one time. Defective products. The cold stamping process of gift packaging boxes has low cost, can save a lot of energy, and has high production efficiency.
It does not need to be heated and then printed. It is a new type of sustainable development process. The loopholes in thermal hot stamping have been filled, and many troubles have been reduced, and the process is also constantly improving.
It also solves the problem of packaging box design and printing.
