1. Use and selection of printing ink

In ordinary packaging printing, water-based ink will be replaced, and it is easy to replace water-based ink. On the other hand, oil-based inks are printed on special packaged food packaging, and they have good adsorption capacity and are difficult to replace.

2. Printing method

The usual packaging method is using a seal, which is printed on the surface of the packaging. Replacing the lining printing of food packaging, the lining printing is printed on the rural side of the packaging, and by recombining and printing on the rural side of the packaging, the printing is not exposed to the outside and can protect the printing color.

3. Accumulation environment

It is important to store the bag, put it on the bag and place it under the sword. In this environment, even if the printing method of the label fades, the bag will still fade. Therefore, please store the bag in a well ventilated place in sunlight. This is the long-term preservation of the flashy colors of the bag.
