QUALITY & COMPLIANCE

Quality Control for Aluminum Foil ContainersSix inspection points from the incoming coil to the export pallet

Every batch of ALKONCE aluminum foil containers is inspected at six control points — from the 8011/3003 coil that enters the workshop to the pallet that leaves it. This page documents the checks we run, the standards we certify against, and the evidence we provide with every order.

HOW WE CONTROL QUALITY

Inspection at Three Stages of Production

Quality is checked while issues can still be corrected — before the press runs, while containers are being formed, and again before the container is loaded for export. In-process and final results are recorded per batch and available to customers on request.

Incoming aluminum coil lot checked for alloy grade and thickness
Inspection example — incoming aluminum coil lot

STAGE 01 · BEFORE PRODUCTION

Incoming Raw Material Inspection

Each aluminum coil lot is checked on arrival before it is released to the production line, with mill certificates retained for traceability.

  • Checks May Cover
  • Alloy grade (8011 / 3003)
  • Temper condition
  • Coil thickness
  • Surface condition
  • Mill certificate retention
  • Supplier lot records
Operator sampling foil containers for dimensional checks during production
Inspection example — sampling containers during production

STAGE 02 · IN-PROCESS CONTROL

Dimension, Weight, Leakage & Seal Checks

During production, containers are sampled and measured against the approved spec sheet, then function-tested for the jobs they will do in your market.

  • Checks May Cover
  • Wall thickness & gram weight
  • Top / base dimensions & depth
  • Water-filled leakage test
  • Lid fit & crimp seal check
  • Heat-seal integrity with film
  • Oven performance (baking & airline)

STAGE 03 · FINAL INSPECTION & SHIPMENT

AQL Final Inspection & Batch Traceability

AQL-based final inspection, batch numbering and retained samples make every shipment traceable back to its coil lot and production date — and every batch inspection report is available with your order.

  • Checks May Cover
  • Appearance & cleanliness
  • Quantity & packing count
  • Export carton preparation
  • Batch number recording
  • Retained samples (12 months)
  • Pre-loading inspection (optional)

ONE STANDARD, EVERY BATCH

Six Control Points for Food-Grade Aluminum Packaging

The same inspection standard applies to smoothwall trays, heat-sealable containers, baking cups, lids and household foil — because your buyers apply the same standard to every product on their shelf.

Incoming Raw Material Inspection

Each aluminum coil lot is checked for alloy grade (8011/3003), temper, thickness and surface condition on arrival, with mill certificates retained.

Thickness, Weight & Dimension Control

Containers are sampled during production and measured for wall thickness, gram weight, top/base dimensions and depth against the approved spec sheet.

Leakage & Lid-Fit Inspection

Water-filled leakage tests and lid fit/seal checks confirm containers and lids match and perform — critical for ready meals and sauced products.

Heat & Sealing Checks

Heat-seal integrity with film and lidding foil is tested where applicable, plus oven performance for baking and airline catering containers.

Food-Contact Testing

Independent SGS testing for heavy metals (Cd, Pb, Hg, Cr VI) and phthalates on finished containers — all results Not Detected.

Final Inspection & Batch Traceability

AQL-based final inspection, batch numbering and retained samples make every shipment traceable back to its coil lot and production date.

IN-HOUSE & THIRD-PARTY TESTING

The Right Test for the Relevant Packaging Risk

We use in-house inspection and independent laboratory testing to evaluate the risks that matter for food-grade aluminum packaging — material safety, dimensional accuracy, sealing performance and shipping condition. Testing is selected according to your project scope and destination market.

MATERIAL SAFETY

SGS Food-Contact Migration Testing

Finished containers are tested by SGS for heavy metals (Cadmium, Lead, Mercury, Cr VI) and phthalates. All results: Not Detected. Reports shared with your RFQ response.

FUNCTION

Leakage & Lid-Fit Testing

Water-filled leakage tests on formed containers and lid fit/seal checks across foil, board and PET lid types — matched to each container rim.

SEALING

Heat-Seal Integrity

Seal strength and integrity checks with lidding film and heat-seal foil for ready-meal and takeaway applications.

TEMPERATURE

Oven Performance Checks

Baking and airline catering containers are checked for oven performance, so trays hold their shape and surface through real service conditions.

DIMENSION

AQL Dimensional Sampling

Wall thickness, gram weight and dimensions are sampled to AQL levels during production, recorded per batch and reported with your order.

TRANSIT

Export Packing & Pre-Loading Inspection

Carton strength, stacking pattern and container loading are checked before shipment — and SGS, TÜV, Bureau Veritas or Intertek inspections are welcome before loading.

CERTIFICATIONS & TEST REPORTS

Verifiable Compliance Documents, Current and Shared

Our registration numbers and certificates are shared with every RFQ response and are available per shipment. Third-party inspection by SGS, TÜV, Bureau Veritas or Intertek is accepted before loading.

EVIDENCE, NOT CLAIMS

Quality Evidence With Every Order

Compliance is something you can hold in your hand. Every ALKONCE shipment ships with a documentation file you can forward to your own buyers and auditors.

PER BATCH

Batch Inspection Report

Dimension, weight and appearance results for your production batch, recorded during in-process and final inspection.

ON RECORD

Material & Process Declaration

Alloy, temper, lacquer and production process on record for each batch — traceable back to the coil lot.

PER SHIPMENT

Certificates in Your Shipment File

FDA registration, ISO 9001 and SGS test documents included with your shipment documentation.

OPTIONAL

Third-Party Inspection Accepted

SGS, TÜV, Bureau Veritas or Intertek inspections are welcome before loading at our Zhengzhou factory.

12 MONTHS

Retained Samples

Samples from each batch are kept on file for 12 months, so any field issue can be checked against the exact production run.

TRACEABILITY

Batch Numbering

Every pallet carries a batch number linking it to its coil lot, production date and inspection record.
