Adhesive and board moisture balance for warp-free case making and packaging.
Guide Stop board warping and cover bubbling on case makers: high-solids low-moisture glue, open time for air release, grey board caliper (1.5–4.0 mm), humidity discipline, and foil/cloth wrap qualification—without treating marketing claims as universal guarantees.
Case study A honeycomb-board converter reduced curl risk and stabilized compression performance by switching to a lower-moisture lamination system that dried more predictably and held panel geometry more consistently.
Case study A premium case-making converter stabilized cloth and laminated cover production by moving to a lower-moisture adhesive program that kept grey board flatter, gave trapped air more time to escape, and reduced corner-lift pressure on automated casemakers.
