1. There is no obvious perforation after the color surface and corrugated cardboard are laminated. Perforation is often caused by too much glue or moisture, which is a common failure of mounting paper.
2. After the color surface and corrugated cardboard are laminated, the deviation of the rules is less than 3mm.
3. The thickness loss of corrugated cardboard is less than 2% after the laminating paper is flattened and bonded. Corrugated paperboard will lose some thickness in the process of mounting paper, but if the thickness is reduced too much, it will affect the use of carton.
4. During the flattening of the colored surface and the corrugated cardboard, the colored surface pattern must not be damaged. The purpose of our processing using the paper mounting process is to get the same good visual effect as printing, so it is a job that can not be ignored to ensure that the patterns are colorful.
5. The color surface and the corrugated cardboard are firmly bonded. After being flattened and completely bonded, the degumming area is less than 1% of the total area. And the degumming position does not affect the quality of the finished product, otherwise it is scrap.
6. Post-finish finishing of veneer to ensure the normal production of die cutting process. Generally, after mounting paper on corrugated cardboard, it needs to be processed on a die-cutting machine, so the post-processing of mounting paper is also very important.
