Die cutting forms the paper box’s shape by cutting through paper or cardboard sheets. It uses a steel die, a sharp blade shaped like the box pattern. The die presses down on the material, slicing out the flat box pieces. This method works well for complex shapes and high-volume runs.
Common die cutting types include:
Flatbed die cutting: Uses a flat surface to press the die into the material. Ideal for thick cardboard and detailed cuts.
Rotary die cutting: Employs a rotating cylinder with the die attached. It’s faster, suited for continuous sheet or roll feeding.
Laser die cutting: Uses a laser beam to cut precise shapes. Great for prototypes or small batches needing fine detail.
Die cutting ensures consistent shapes and clean edges, essential for proper folding and assembly.
After cutting, paper boxes need creases to fold neatly. Creasing creates a slight indentation without cutting through the material. It prevents cracking or breaking when folded.
Common creasing methods:
Blade creasing: Uses a sharp blade to score the fold line. Suitable for thin materials.
Rule creasing: Employs a blunt metal rule pressed into the sheet. Better for thicker cardboard.
Embossed creasing: Combines creasing with embossing to add texture along fold lines.
Folding usually follows creasing. It can be manual or automated. Proper creasing and folding keep the box’s shape sharp and durable.
Modern paper box production relies on specialized machinery for accuracy and speed:
