Not all cardboard boxes are standard rectangles

The e-commerce and retail industries are increasingly using irregular cardboard boxes (such as hexagonal boxes, drawer boxes, and top and bottom covers), and the sealing and gluing path is much more complex than standard unboxing. Here are 5 common types of irregular box shapeshot melt adhesive pelletsGlue application plan.

  • 1. Heaven and Earth Cover BoxApply a circle of adhesive line (circumference x 1 line) on the inner wall of the cover, and there is no need to apply adhesive on the bottom. The glue line should be 5mm away from the edge to prevent glue overflow. The amount of glue used is about 1.5-2.0g/piece.
  • 2. Drawer style boxApply 2 parallel adhesive lines to the bottom of the outer side of the drawer (fixing the inner tray), and apply 3 adhesive lines to the inside of the outer cover (fixing the partition). The total amount of glue used is about 2.5-3.0g/piece.
  • 3. Hexagonal display boxApply one adhesive line to each of the six edges, and apply six short adhesive lines (corresponding to the six buckle positions) on the cover. The total amount of adhesive used is about 3.0-4.0g/piece.
  • 4. Book boxApply a long adhesive line (magnetic suction surface+double-sided adhesive coating on the spine surface) to the spine of the book, and apply adhesive lines around the inside of the cover. The total amount of glue used is about 2.0-2.5g/piece.
  • 5. Alien corner boxAdd a 5cm adhesive line at each corner for reinforcement, and the main sealing path should be the same as the standard box. The total amount of glue used is 0.5-1.0g/piece more than the standard box.

Sunlife hot melt adhesive particles have good fluidity and precise positioning in irregular gluing scenarios, making them suitable for various automatic gluing equipment.

Frequently Asked Questions (FAQ)

Q: Can robots be used for gluing irregular boxes?

A: Okay. The six axis glue coating robot, combined with visual positioning, can accurately track any irregular path. Sunlife hot melt adhesive particles with low viscosity are suitable for precise coating by robots.

Q: How to verify the sealing strength of the irregular box?

A: Perform a drop test according to the courier standard (1.2m free fall, 1 test on each of the 6 sides), and if there is no wire breakage or unpacking, it is considered qualified.
