Custom food packaging fails quietly — color drifts a half-shade, a valve seats off-center, a heat seal weakens in week three of transit. We catch those failures four times: at the dock, on the press, after lamination, and before the container leaves. Every gate is logged. Every report ships with the goods.
If it fails: Non-conforming rolls returned to supplier within 24h.
If it fails: Out-of-spec sections marked for slitting waste; root cause logged.
If it fails: Failing lots rerun or downgraded; never blended into ship lot.
If it fails: Failed lot held; client notified before ship date.
Press-side color measurement. ΔE calibration to physical Pantone reference.
BST / EyeC class, full-web 100% inspection during roll-to-roll print.
Per-shift heat-seal validation at 3 dwell temperatures.
Mocon-equivalent. Oxygen and moisture transmission tested per barrier lot.
EU 10/2011 and FDA 21 CFR test panel run at accredited third-party lab per stack.
Layer-thickness verification on laminate cross-sections.
Quality assurance is only credible if it is verifiable. With every shipment we attach a documentation bundle that lets your QA team trace any deviation back to a press run, a shift, an operator, and a physical retain sample held in our archive.
On annual contracts we publish a quarterly defect-rate dashboard, broken down by SKU and press, so you can see how your account is tracking before issues surface.
Standard outgoing AQL is 2.5 per ISO 2859-1. Critical defects tracked separately at AQL 0.65. Clients can request tighter AQL at quote stage.
Yes. We keep one signed retain sample per SKU per batch for 24 months, with run conditions logged. Any future quality dispute is reconciled against this reference.
Yes. We host pre-ship inspections in-person or via live video. We also support third-party inspection bookings (SGS / Bureau Veritas / Intertek) at client cost.
The lot is held — never blended into a passing batch. We notify your buyer within 24 hours with a root-cause report and offer a rerun or partial-ship plan in writing.
Migration tests are revalidated annually per stack, or whenever a material supplier changes. The current report is included with every shipment using that stack.
We target ΔE < 2.0 against a physical Pantone Solid Coated reference. Brand color libraries (custom Pantones) are kept on file and re-validated on each press run.
