Flexo printing process application of folding cartons

Folding carton usually refers to the carton that is formed by folding and combining the thin cardboard after die cutting and creasing. Before the goods are shipped, such cartons can generally be folded into flat plates for stacking, transportation and storage, thereby saving storage space and transportation costs. The folding carton that serves as the outer packaging of the product must not only have sufficient strength, excellent design of pattern decoration, but also should have excellent surface printing quality. Only in this way can we ensure the safety of the transportation of goods, but also play a role in beautifying the goods, increasing the added value of goods, and promoting the sale of goods. At present, folding carton is a commodity sales packaging container with the widest range of applications and the most structural changes. It has been widely used in packaging fields such as food, medicine, electronic products and cosmetics.

At present, folding carton printing is a hot spot for flexo and offset printing to gain market share. In the past, due to the fact that the print quality of flexo printing cannot be compared with offset printing, it is generally only suitable for the field of flexible packaging printing. For example, paper or plastic flexible packaging, corrugated board printing, and trademark label printing are often excluded from the folding carton printing market. However, with the improvement of equipment and technology, the quality of flexographic printing has greatly improved.

In early 1998, European and American printing companies had tried to introduce flexographic printing technology into the folding carton printing market. As a result, it was found that the high-grade surface decoration effect created by flexo printing has brought endless room for development in the field of folding carton printing. The market share of flexo printing in the field of folding cartons is continuously increasing. Flexo printing has the following obvious advantages in the folding carton printing market:

1. Flexo can allow multiple processes to operate online. On-line production lines can combine printing, die-cutting, slitting, laminating, molding and other process steps to achieve front-end input roll materials and output finished product packaging.

2. The surface smoothness of flexographic printing materials is not very high. People can use low-cost recycled paper or cardboard to print folding cartons, which can also save 20% to 40% of raw material costs.

3. The water-based ink used in flexo printing is non-toxic and non-polluting, which is beneficial to the protection of the environment. Therefore, flexo printing is a green printing method that meets the current needs of environmental protection.

4. Flexo printing reduces the chance of bad prints. According to statistics, the probability of bad prints in flexo printing folding cartons can be reduced by 8% compared to other printing processes.
