Quality Assurance Protocol

Four-Stage Barrier Quality Protocol

Every production batch moves through four documented inspection checkpoints before ocean export.

Stage 01

Substrate & Raw Polymer Verification

Before printing or extrusion, virgin polymer substrates (BOPP, PET, BOPA Nylon, Aluminum Foil, PE) undergo surface corona dyne checks and micrometer thickness verification.

Key Laboratory Procedures:

Dyne level corona test (≥38 dyne/cm for ink adhesion)

Ultrasonic thickness uniformity scan (±2% tolerance)

Solvent-free adhesive viscosity & purity audits

FDA 21 CFR 177 & EU 10/2011 food-contact migration docs

Stage 02

Inline Press High-Speed Optical Monitoring

During 10-color gravure or digital printing at up to 400 m/min, German BST optical cameras scan 100% of the continuous web to capture microscopic streaks and registration drift.

Key Laboratory Procedures:

X-Rite spectrophotometer color matching (Delta-E < 2.0)

Cylinder registration alignment within ±0.05 mm

ISO/IEC 15415 Grade A barcode and QR code verification

Laser gloss and matte varnish contrast inspection

Stage 03

ASTM In-House Barrier & Vacuum Leak Lab

Converted pouches undergo rigorous physical and chemical tests inside our ASTM certified cleanroom laboratory, verifying hermetic barrier integrity under extreme negative pressure.

Key Laboratory Procedures:

ASTM D3078 bubble emission vacuum leak test (-90 kPa)

Universal tensile heat-seal strength (≥30 N/15mm)

Interlayer peel strength test following 48h curing

Gas chromatography (GC) residual solvent < 5.0 mg/m²

Stage 04

Cleanroom Packing & Port Drop Verification

Pouches are count-verified, sealed in heavy-gauge polyethylene inner liners, packed in 5-ply corrugated export cartons, and secured onto fumigated pallets with edge-protector guards.

Key Laboratory Procedures:

1.2-meter export carton drop test (ISTA-1A standard)

PE inner moisture barrier wrapping with desiccants

Unique lot traceability barcodes on every master shipper

Signed Certificate of Analysis (COA) issued per batch

International Food Compliance & Factory Accreditations

Audited by SGS and TÜV Rheinland to satisfy stringent global food-contact safety standards.
