Deep Drawing Food Container Aluminum Circle

Core Advantages

• Superior deep‑drawing performance, high elongation, support one‑time deep stamping for deep‑wall seamless food containers, low earing rate, reduce material waste

• Food‑grade raw material, comply with LFGB / FDA food‑contact requirement, non‑toxic, odor‑safe for direct food contact

• Clean mill‑finish surface, free of oil stain and abrasive residue, suitable for subsequent anodizing, non‑stick coating

• Good thermal performance, adapt for high‑temperature heating and cold refrigeration environment

• Precise dimensional tolerance, stable mechanical property, compatible with high‑speed automatic container stamping production line

• 3003 alloy option brings better rigidity, finished container anti‑deformation during stacking and transportation

• Burr‑free trimming edge, no sharp burr after blanking

• Fully recyclable aluminum material, eco‑friendly for food packaging industry

Production Process

Aluminum big coil uncoiling → Degreasing washing → High‑temperature full annealing treatment → Flattening & leveling → Precision blanking stamping into round circles → Edge deburring → Deep‑drawing sample test → Surface visual inspection → Flatness checking → Separated by interleaving anti‑scratch paper → Export packing Each batch conducts deep‑drawing simulation test, food‑contact safety inspection and dimension check before shipment.

Technical Parameters

Application

Food packaging: Seamless food bowl, metal lunch container, take‑away food vessel, food storage can Kitchen utensils: Food mixing bowl, salad bowl, multi‑purpose food holding container Commercial catering: Large‑capacity catering food containers, bakery food holding vessels Processing factory: Raw blanks for deep‑stamped seamless food containers, subsequent coating & anodizing base material

Export Packaging

Each aluminum circle separated piece‑by‑piece by interleaving kraft paper to avoid scratch. Neat stacked, wrapped by moisture‑proof PE film. Loaded onto IPPC fumigated wooden pallets, fastened by packing straps. Shipping marks mark alloy grade, temper, thickness, diameter, net weight, gross weight and batch number. Mill Test Certificate, food‑contact safety report and fumigation certificate can be offered for incoming inspection and customs clearance.

FAQ

Q1: Which temper for deep‑draw food container circles? A: O annealed temper is mandatory, high elongation to realize deep‑wall seamless container without cracks.

Q2: Alloy selection suggestion? A: 1060‑O for cost‑effective light‑weight food containers; 3003‑O for heavy‑duty containers with higher anti‑deformation requirement.

Q3: What is earing? A: Earing is uneven edge after deep drawing. Our material strictly control grain structure to reduce earing rate, save trimming cost for container factory.

Q4: Can it contact oily & hot food directly? A: Yes, raw material meets international food‑contact standard for hot, cold and oily food.

Q5: Common thickness for food container? A: 0.8‑2.0mm for daily food bowl & lunch box; 2.0‑4.0mm for heavy‑duty large‑size catering containers.
