Common rigid-box gluing problems: symptoms, causes and fixes, citing adhesive makers' published technical guides.
Why does hot melt glue string, and how do I stop it?
Stringing ("angel hair") usually means the glue is cutting off poorly at the nozzle: the nozzle is too far from the work, the glue is too cool and viscous,
→Why Hot Melt Glue Won't Stick to Your Box Wrap
Weak hot melt bonds usually come from glue that is too cool to wet the surface, too little glue, poor pressing, a hard-to-bond surface (film-laminated or U
→Hot Melt Nozzle Clogging, Charring and Smoking
Clogged nozzles are usually caused by char: glue degraded by heat, oxygen, contamination and time. Dust and debris in the tank, long idle periods at full t
→Glue Not Drying or Sticking in Cold Weather
It depends on the glue. White/PVA glue has a minimum application temperature on its data sheet (for example, one PVA TDS lists 8°C) — check yours and keep
→Why Rigid Boxes Warp: Glue Amount and Moisture
A common cause is too much water-based glue. LD Davis, a maker of gelatin glue for rigid boxes, notes that extra glue doesn't make a stronger bond, and bec
→Hot Melt vs White (PVA) Glue for Rigid Boxes
They behave differently. Water-based glues are applied as a liquid, and excess glue adds moisture that can warp board (LD Davis, on gelatin glue); PVA also
