Kraft paper is an important paper packaging material in the field of printing and packaging, and has also been widely used and recognized by consumers. If your peers have a better solution, you may wish to publish it and share it with everyone.

Kraft paper color difference is a problem faced by the whole industry, both factories and customers are troubled by this problem, and Gali is also one of them. The causes of color aberration are varied and unavoidable. Chromatic aberration is mainly based on prevention.

When encountering color differences, it is necessary to communicate well with customers, and transactions can only be made after customer confirmation. In addition, when buying kraft paper, try to find a large manufacturer to buy, and the quality is also better.

Kraft paper due to different raw materials, different production batches, different production seasons, different production machines, etc., many round macro reasons are Changtong collapse will affect the color of the kraft paper roll base paper is not the same, this color is difficult to avoid, and can not be controlled, Jiali Paper pointed out: generally the same batch of kraft paper can ensure 98% color consistency.

Pay attention to the time of proofing and making large goods do not drag on for too long, the same batch of cattle wheel dry high parchment paper has been out for a long time, the next batch does not dare to guarantee that the color is very close, and the color of the kraft paper will change if it is too long.

Second, if it is an export order or the customer has strict requirements for the color of the product, it is recommended to order enough kraft paper at one time to avoid halfway or later **, after all, the kraft paper bought back in the same batch will not be too far away even if there is a little color difference.

The moisture content of the paper will lead to quality problems in printing, and the tight edge phenomenon and ruffle phenomenon are all caused by the moisture content in the kraft paper. In the process of kraft paper from the paper mill to the printing plant until it becomes a printed matter, due to the changes in the temperature and humidity of the surrounding environment in the transportation, storage, use and other links. The molecular structure of paper fibers contains hydroxyl groups to form hydrogen bonds, which expand hydrophilically when wet and dehydrate and shrink when dry.

When the paper has a tight edge, sprinkle more water around the paper pile or machine to reabsorb water around the paper; When the ruffle appears on the paper, it can be knocked by hand to increase the stiffness of the paper when it is slight, and the paper needs to be hung again when it is serious.
