Rigid Gift Box Converters Flag Grey Board Caliper Substitutions on Spot Buys
Gift box plants caution that spot grey board purchases may substitute nearby calipers, affecting wrap quality and magnetic closure fit.
Rigid box converters warn that spot-market grey board can arrive with caliper substitutions when preferred thickness is short, affecting wrap tension and lid fit on magnetic or ribbon closures.
Brands approving samples on one caliper should require the same board ID on mass production POs, with incoming micrometer checks.
Buyer takeaways
Lock board caliper and density on the PO.
Re-approve samples if board lot changes.
Inspect lid gap and wrap corners on first bulk carton.
