The "flexible bond" for cross-border adaptation - The diverse applications of creasing lines

With the development of material technology, the application of creasing lines has long broken through the paper field and become a "flexible link" connecting different materials. In the plastic packaging industry, high-temperature resistant polyimide creasing lines can create precise creases on plastic films such as PET and PVC, enabling smooth opening and closing of plastic gift boxes and food preservation box LIDS. In the field of metal processing, specially designed hard alloy indentation lines can leave positioning indentations on thin aluminum sheets and tinplate surfaces, providing precise references for subsequent welding and assembly.

In the fields of cultural and creative industries as well as office work, the application of creasing lines is even more ingenious. The "loose-leaf core" commonly used by journal enthusiasts, with its dotted crease line on the edge, makes the paper easy to tear off and the edge neat. The three-dimensional inserts in children's picture books, through the combination design of multiple sets of crease lines, achieve a three-dimensional shape when the page is unfolded, stimulating children's interest in reading. Even in the medical field, the crease lines on the aluminum-plastic blister packaging for medicine can separate the tablets independently, making it convenient for patients to accurately take the dosage. From industrial production to daily necessities, creasing lines, with their strong adaptability, interpret the value of "success or failure is determined by the details" in various fields.
