How to distinguish the advantages and disadvantages of carton creasing line (a)

Indentation line as an important material for die cutting after printing, has an important impact on the indentation and molding of the carton. To get the perfect indentation, a good quality indentation line is an essential helper. However, in today's market, there are many inferior indentation lines, shoddy. If the carton factory chooses a poor quality indentation line, it will easily lead to a decrease in the quality of the carton indentation, a decrease in production efficiency, and even a customer return. To bring great losses to the manufacturers. Therefore, the right choice of indentation line, identify the merits of indentation line helps manufacturers to create greater profits. How to identify the quality of products, we can start from the following aspects:

Indentation groove width and height error

Inferior indentation lines are mostly produced by small factories. These small factories generally do not have specialized laboratories for product R&D and quality control. As a result, the products produced are not uniform and have poor accuracy and errors. If the model is 0.5X 1.5mm indentation line, according to the laboratory strict test, the width of the indentation groove of the inferior quality indentation line is actually 1.6mm-1.8mm, and the actual measured value is not at its standard value of 7.5mm. Within range. The quality of the same type of indentation line, indentation groove width range of 1,48mm ~ 1.53mm, the error can be controlled within 2%. Another example is the height of the indentation trough, the measured value of the inferior indentation trough height is 0.52mm~O. 55mm, the maximum error reached 10%. For high-quality products of the same type, the measured height of the indentation groove is between 0.50mm and 0.51mm, and the error is completely controlled within 2%. It can be seen that the indentation groove of the inferior creasing line has a very large error and it is easy to produce a series of quality problems.
