Short version fast printing stores often struggle between hot melt adhesive particles (glue packaging) and white glue/latex water (lock thread or brush glue) when making joint albums and conference manuals. We compare from three aspects: speed, fastness, and appearance.
| Dimension | Hot melt adhesive granules | White milk glue |
|---|---|---|
| speed | Instant curing, suitable for urgent orders | Need to air dry, slow down |
| fastness | Penetrating well and spreading evenly without losing pages | Thin paper is prone to wrinkling, while thick sheets are easy to open |
| Appearance | Neat and seamless spine | There may be adhesive marks |
| Device | Glue installation machine is required | Just brush the glue, low threshold |
Same as the copperplate paper register, after brushing with white glue, it needs to be clamped and fixed for half a day. Even after flipping it several times, there is still glue peeling; Sunlife hot melt adhesive particles are spread out on the spot and flipped repeatedly without peeling off, and customers can take them away and use them immediately. For fast printing shops, the investment in adhesive machines is quickly recouped by the efficiency of urgent orders.
Q: Is there no adhesive machine that can use hot melt adhesive granules?
Answer: A manual glue gun can be used for small quantities, but its efficiency is not as good as an automatic line.
Q: Is glue cheaper?
Answer: Single material costs may be low, but labor hours and rework costs may be high, which may not necessarily save overall costs.
Q: Which is suitable for high-end picture books?
Answer: The combination of lock thread and hot melt adhesive particles provides the most stable backing, while Sunlife particles penetrate evenly.
Fast printing store upgrades adhesive packaging and seeks Guangzhou Sunlife Trading to test Sunlife hot melt adhesive samples on the machine.
