Four-stage inspection against an approved physical sample.
Every XHANCO order is produced against a client-approved physical sample and a written specification sheet. Quality is managed by an independent QC department that reports outside production, operating under ISO 9001, ISO 14001, ISO 45001 and ISO 22000 management systems, supported by an in-house laboratory and full batch traceability.
No material enters production before it is verified against the approved supplier specification.
Operators and roving QC inspectors sample at fixed intervals throughout each run.
Finished goods are sampled by AQL plan and tested for functional performance.
An independent audit before the goods are released to the container.
| Control point | Method | Acceptance basis |
|---|---|---|
| Dimensions & format | Calibrated steel rule, calliper and web-width gauge | Approved dieline / specification sheet tolerance |
| Grammage & thickness | Precision balance for gsm; micrometer for film gauge | Nominal value with agreed tolerance band |
| Registration accuracy | Registration marks read under magnifier during the run | Within the tolerance stated on the approved proof |
| Colour consistency | Spectrophotometer, ΔE measured against Pantone and physical master | Target ΔE < 1.5 on primary brand colours |
| Sealing strength | Tensile tester on heat-sealed specimens | Seal must not fail below the agreed force value |
| Leakage & barrier | Water and pressure leakage test; barrier structures verified on laminate | Zero leakage on liquid-bearing formats |
| Quantity verification | Counting at the packing line, weight cross-check on master cartons | Exact declared inner-pack and carton counts |
| Scannability | Barcode verifier on printed labels and tags | Readable first-pass for logistics automation |
Tensile and elongation testing, heat-seal strength, peel and bond strength, burst and drop testing on finished bags and cartons.
Spectrophotometric ΔE measurement, standard light-box viewing, rub and scratch resistance, ink adhesion tape test.
Moisture and oxygen barrier verification on laminate structures, seal integrity, coefficient of friction and anti-fog performance.
Food-contact migration and heavy-metal testing arranged with accredited third-party laboratories, with reports issued per material batch.
X-ray inspection and handheld metal detection run alongside the four-stage QC flow, catching physical contamination that dimensional and colour checks cannot.
Detects metal, glass, stone and other dense foreign bodies inside sealed packs before release.
Spot-checks finished goods for metallic contamination at the line and during final audit.
