Folding carton quality control

With the continuous development of the packaging and printing, folding cartons are more and more popular in the market. A lot of product packaging with plastic, wood, iron, etc. materials changed into folding carton. The paper-based materials packaging products, its shape can overcome the packaging limitations, takes full advantages to the paper good physical and printing applicability. By the physics of the paper and printing adaptability, we can design the exquisite pattern and shape after the molding process with a variety of processing. Thereby increasing the value of the products, improve the ability to sell. Folding carton, it has the characteristics of the capacity, protection, convenience, display, exhibition, artistic, environmental protection and economic benefits favored by the majority of product manufacturers.

However, a lot of folding cartons in market liquidity, there is a wide variety of quality problems. This must pay attention by the packaging and printing workers seriously, we must carefully analyze these problems. To improve the quality of folding cartons, I think it should start from the following aspects:

1. Design

The manufactures expect to be able to show their product innovation in the folding carton box so that consumers have a fresh feeling so as to achieve the purpose of promotion. Therefore, the design is a vital part of the folding carton for quality assurance. It must reach a comprehensive reflection of the effect of pattern, color, text, highlight the subject, taking into account the feasibility and effect of plate making and printing and processing. As much as possible to avoid using too small font and unnecessary complex patterning which is difficult to print.

2. Paper

As for Paper, taking into account the load product during transport to maintain the shape, not to be damaged. We must choose a certain weight of paper. For instance, some products under its own weight, we use high-weight paper, even some of the same gram paper mounted on the carton to ensure stiffness or compressive strength. Otherwise, only emphasizes the cost, reduce paper weight, it will have quality problems, resulting in a counter productive waste.

3. Ink

The ink is the main component of the color composition. For ink selection is very important. In addition to the consideration of hue, we must also pay attention to its resistance to anti-performance level. In particular, heat resistance, cold resistance, alcohol, acid, etc. indicators. But also the index of the alkali in the alkaline product packaging, some folding carton boxes after storage and transportation have the color fading phenomenon, that's the ink problem.

4. Printing

According to the characteristics and requirements of the product, we can use different printing methods. Usually we apply offset, flexo, screen printing, gravure printing method, regardless of which method applied, we have to guarantee the quality of printing. First, we must understand the specific printing requirements of the customers.

5. Post-processing

This part is very important. If not handled properly will cause immeasurable loss. In the post-processing, we must strive to do the handover of the various processes and quality control. For example, some folding carton products to the auto assembly line packaging, we should apply laser instead of manual arrange the knife. In addition, the use of adhesive bonding after a certain hot, cold experiments confirm adhesion fastness before a large number of trial.

In short, as the application of the folding carton in the market, as a packaging printing manufacture need to be sure to take actively supporting measures, in particular, to control the quality of the folding carton packaging boxes seriously sum up experience and take active measures to ensure the quality of the box for ease of use.
