Non-Stick Coated Aluminum Coil for Cookware

1. Core Advantages

• Integrated food-grade non-stick double-layer coating

  The coil is pre-coated with food-safe primer and high-temperature non-stick finish in factory, the coating is non-toxic, odorless and harmless when contacting food, meeting EU food contact testing standards.

• Excellent high temperature resistance

  The non-stick top coat can withstand long-term working temperature up to 260°C, no decomposition, discoloration or harmful substance precipitation under normal cooking and baking environment.

• Super strong coating adhesion for deep drawing

  The matched flexible primer and ductile aluminum substrate support complex deep drawing, stretching and edge curling; coating keeps intact without peeling or bubbling on the curved surface of pan bottom and pan edge.

• One-step forming, reduce secondary processing cost

  Cookware manufacturers can directly stamp finished pans/trays without re-spraying non-stick paint, simplify production procedures and lower workshop pollution.

• Smooth easy-clean non-stick surface

  The compact non-stick coating effectively prevents food adhesion during cooking, oil and food residues can be wiped off easily with soft cloth, convenient for daily cleaning.

• Stable flat substrate for mass production

  Adopts stress-relieved 1060 O / 3003 H24 aluminum alloy, uniform thickness without warping, high yield rate for continuous stamping production lines.

• Customizable coating color & surface texture

  Available in black, grey, beige non-stick finish; matte and fine smooth surface optional, special color matching for customized kitchen appliance appearance.

• Safe protective film for processing

  Surface covered with high temperature resistant PE protective film, effectively avoiding scratches and contamination during slitting, stamping and storage.

2. Production Process

Aluminum coil uncoiling → Multi-cycle degreasing & surface cleaning → Food-grade non-chromium passivation treatment → Constant temperature drying → Food safe adhesion primer roller coating → High temperature curing → High temperature resistant non-stick top coat coating → Secondary baking curing → Natural cooling → Anti-scratch protective film lamination → Precision rewinding → Food safety & high temperature resistance testing → Deep drawing simulation inspection → Full surface defect screening → Dust-proof export packaging

Every batch of finished coils will pass strict food contact migration test and high temperature baking test before delivery to ensure compliance with global kitchenware production standards.

5. Export Packaging Standard

Each non-stick coated cookware aluminum coil is wrapped with multi-layer dust-proof and moisture-proof PE film plus thick neutral kraft paper. The non-stick coating surface is fully covered with high temperature resistant protective film to avoid friction scratches during stamping and long-distance sea transportation. Coils are fixed tightly on fumigated wooden pallets with high-strength steel strapping to prevent loose roll and deformation. Clear shipping marks are printed including alloy grade, thickness, width, coating type, color code, net weight, gross weight and batch number. Complete fumigation certificate, MTC, LFGB/FDA food safety test reports and full set customs clearance documents can be supplied for overseas kitchenware factory import inspection. Narrow slit small coils are packed into independent sealed cartons for separate protection.

6. Inspection & After-sales Service

We carry out eight strict pre-shipment inspections: coating thickness test, food contact migration test, high temperature baking resistance test, deep drawing simulation test, cross-cut coating adhesion test, color difference inspection, flatness detection and full surface defect screening. Complete supporting documents including Mill Test Certificate, LFGB & FDA food safety report, RoHS environmental certificate, commercial invoice and packing list can be provided for customer factory audit and customs clearance. Our professional technical team provides free deep drawing stamping parameter guidance for cookware production at any time. If coating peeling, bubbling or surface quality defects are confirmed within 7 working days after receiving goods, we will reply within 24 hours and provide targeted solutions including re-production, supplementary shipment or reasonable compensation.

FAQ

Q1: What’s the difference between this non-stick coil and ordinary food-grade aluminum coil Item 6?

A: Item 6 only has common food-safe PE coating without non-stick function, needs secondary spraying for cookware; No.14 has integrated high-temperature non-stick coating, can be directly stamped into finished pans without re-spraying.

Q2: Is the coating safe for food contact?

A: All coating raw materials meet FDA and LFGB international food safety standards, non-toxic and no harmful substances will separate under normal cooking temperature.

Q3: Can the coil withstand deep drawing for round frying pans?

A: Yes, flexible coating and soft aluminum substrate support deep stretching, curling and complex forming without coating cracking or peeling.

Q4: How long can the non-stick coating last after forming cookware?

A: Under normal household use, the non-stick performance can be maintained for a long time, resistant to daily high-temperature cooking and repeated cleaning.

Q5: What food safety certificates can you provide for export?

A: We can supply LFGB, FDA food contact test report, MTC, RoHS certificate and complete export customs clearance documents.
