Here are 5 common types of irregular box shapeshot melt adhesive pelletsGlue application plan.

Sunlife hot melt adhesive particles have good fluidity and precise positioning in irregular gluing scenarios, making them suitable for various automatic gluing equipment.
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.
What do we need to inspect when replacing the adhesive particles for book and magazine packaging and making samples? Directly provide the list: When changing the glue or selecting a new supplier, a sample must be made and checked before formal productionAdhesive strength, page flipping flatness, appearance of book back, temperature resistance, opening time, odor, […]
