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.

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.
Maintaining consistency is crucial for binding applications. – Managing processes and materials can lead to the best results. In terms of binding materials, manufacturers are seeking solutions that feature high durability, temperature and moisture resistance, as well as strong adhesion to various substrates. The formula of the binding hot melt adhesive product portfolio exceeds the […]
EPE pearl cotton (foamed polyethylene) has a loose texture, poor high temperature resistance, and strong surface inertness, making it a difficult material to bond in the packaging industry. Ordinary hot melt adhesive is prone to problems such as melting through cotton, weak adhesion, low-temperature cracking, high-temperature delamination, pungent odor, and wire drawing affecting the appearance […]
Direct answer: High fluidity hot melt adhesive particles are suitable for high-speed production lines, fine nozzle dispensing, thin paper/porous substrate penetration, and large-area pasting; For scenarios such as thick book back adhesive, vertical surface bonding, and heavy load bearing, conventional or high viscosity models are more suitable.There is no superiority or inferiority in liquidity, only […]
Hot melt adhesive granulesIs it better to have a higher viscosity? No. Viscosity is just one of the many parameters of hot melt adhesive. Blindly pursuing high viscosity can lead to problems such as overflow, penetration, and difficulty in cleaning. Choosing particles depends on “matching”, not on a single number. Key parameter list Melt viscosityAffects […]
