The corrugated slotting process plays a crucial role in converting flat corrugated sheets into functional and sturdy boxes used for various packaging applications. It involves a series of intricate steps that transform flat cardboard into boxes of different sizes, shapes, and strengths.

Raw Materials

The process начинается with large rolls of corrugated cardboard, which is composed of three layers: two outer liners and a corrugated medium. The outer liners provide strength and stiffness to the box, while the corrugated medium creates cushioning and insulation.

Slotting and Scoring

The cardboard sheets are then fed into a slotting and scoring machine, which uses sharp knives to create slots and score lines in the cardboard. Slots are used to lock the box flaps into place, while score lines facilitate easy folding of the flaps. The machine precisely cuts and scores the cardboard according to pre-determined dimensions, ensuring the correct placement and alignment of the flaps.

Folding and Gluing

After slotting and scoring, the cardboard is folded along the score lines to form the basic box shape. The flaps are then folded and glued into place, creating a secure and durable closure. Glue is applied to specific areas of the flaps, ensuring a strong bond that holds the box together during transit and handling.

Box Assembly

The folded and glued boxes are then assembled into their final form. This may involve manually or automatically folding the flaps at the corners and securing them with additional glue or staples. The completed boxes are then inspected and packed for shipment or storage.

Customization and Design

The corrugated slotting process allows for a wide range of customization options to meet specific packaging requirements. Boxes can be designed in various sizes, shapes, and configurations. Printing and branding can also be added to enhance the visual appeal and brand recognition of the packaging.

Quality Control

Throughout the slotting process, rigorous quality control measures are implemented to ensure the boxes meet the highest standards. Automated inspection systems can detect any errors or imperfections, such as misaligned slots or weak glued joints. Boxes are also tested for strength and durability to ensure they can withstand the rigors of shipping and handling.


The corrugated slotting process is a critical step in the manufacturing of cardboard boxes. By transforming flat sheets into functional and diverse containers, this process enables the packaging industry to meet the diverse needs of consumers and businesses alike. The precise execution of slotting, scoring, folding, gluing, and assembly ensures the boxes are sturdy, durable, and customizable, making them an indispensable part of modern packaging solutions.
