Does the carton indentation line affect the tape opening?

In the process of carton forming, the indentation line mainly plays the following roles: it is easy to fold, and the crease is flat and beautiful. Determining the external size and crease standard of carton can improve the compression resistance of carton.

Generally, the indentation depth of three-layer cardboard boxes has little effect on tape packaging.

If it is a five-story carton, the pressure line is too shallow, which will cause excessive reverse stress at the corner of the indentation on the upper cover of the carton. If the carton is sealed with tape for a long time, it may cause glue opening, but this is only some factors of tape opening.

If there is nothing wrong with your tape, you should also consider whether the cardboard on the outer layer of the carton is the same as the previous cardboard.

Poor hanging pulp on the surface of the paper card, or the hanging pulp on the surface of the paper is easy to fall off, will also cause the tape to open.

Some papermaking processes will glue the surface of cardboard. In order to improve the strength and moisture-proof performance of paperboard, this type of paper may affect the opening of adhesive tape.

If the surface of your box is printed or polished, the types of printing ink and polishing oil may affect the tape.

Carefully observe the suspicious places on the surface of tape and paper, boldly infer and try. It shouldn't be difficult to solve this problem.
