Why is the proofing fee of bubble express bag high?

First of all, let's first say the conclusion, because this is a machine proofing, this process is exactly the same as making large goods, so when the cost is evenly spread on several samples, it is very high.

Our production process is first printing, printing our factory has a professional printing machine, the machine can print up to 8 colors at a time. Of course, the more color printing design, the higher the cost, because the cost of this first is the cost of ink, and then, the more color printing, we need to debug the material also need more, the loss of materials will increase, which is undoubtedly a major cost for the lower price of bags.

After the printing is completed, we will blow the bubbles, as well as other materials, and use a professional compounding machine to compound these different layers of materials together. Because the material of the bubble is PE, it can be combined with CPE without the help of glue, and other materials need to be combined with the help of glue. This is the same as the production process of large goods, such a large machine naturally needs a lot of costs, in addition to the waste of materials debugging the machine.

Therefore, in the entire production process, printing machine, composite machine, bubble machine, bag making machine, these machines need to boot several sample bags, and the start-up cost and debugging cost are essential. Therefore, in the case of a small number of customers' orders, we do not recommend customers to make customized samples. Customers generally want to know the presentation effect of their printing design, but for customers with small bulk orders, the cost of this proofing is almost the same as the cost of bulk goods, it is not a suitable choice.

As a factory, we can provide inventory, other customers' products before, free of charge to our customers reference product quality and printing. The other is to first give the large sample to the customer for confirmation when doing large goods. That's one way.

Let's sum up, the reasons for the high proofing cost of composite bubble express bags, most of the cost is because the production process is consistent with the bulk goods, all the required machines need to be opened, and the cost of debugging is indispensable. The other part is that the printing design is very complicated, requiring more than 4 colors of printing, and the loss of this proofing is also high. These two reasons make the proofing fee of composite bubble express bag high. Therefore, if possible, it is recommended to refer to our stock samples.
