Corrugator Starch Makers Update High-Speed Single-Face Glue Guidance for Mid-Year Runs
Starch adhesive suppliers are refreshing high-speed single-face glue guidance as converters chase output without raising delamination risk.
Corrugator starch adhesive makers are updating mid-year guidance for high-speed single-face lines, focusing on gel temperature windows, solids control, and storage rules during humid weeks.
Converters running faster without matching glue prep are seeing bond variation that later appears as flute separation in export stacks—especially on recycled medium mixes.
Why buyers care: board suppliers and carton plants may blame each other unless glue parameters and board moisture are documented together.
Buyer takeaways
Require gel temperature, solids, and viscosity method on starch TDS.
Log glue-kitchen settings against each board construction trial.
Re-check bond after any medium grade substitution.
