Inside Our Production Line: How Aluminum Trays Are Made

Publish Time: 2025-12-09     Origin: Site

As a leading manufacturer of disposable aluminum foil containers, we know that global buyers care about stability, hygiene, and production capacity. Here is a behind-the-scenes look at how our factory turns premium aluminum foil into durable, food-grade trays trusted worldwide.


1. Raw Material Selection

We source high-purity, food-grade aluminum foil rolls. Each roll undergoes thickness, tensile-strength, and alloy verification before entering production. Stable raw material ensures consistent container strength and oven-safe performance.


2. Fully Automatic Pressing & Forming Lines

Our factory operates 30+ automatic high-speed production lines, capable of producing thousands of trays per hour.
Key features:

  • Precision molds for pizza pans, cake pans, lunch boxes, BBQ trays, etc.

  • Stable weight and wall thickness

  • Smooth edges for safe handling

  • Custom shapes supported (round, rectangular, multi-compartment)

Automation greatly reduces human contact and improves consistency — a key requirement for food packaging buyers.


3. Embossing, Trimming & Curling

Each tray goes through shaping, edge curling, and reinforcement steps. This ensures the container is strong enough for:

  • high-temperature baking

  • freezing

  • long-distance transportation

  • stacking without deformation


4. Quality Control & Inspection

Our QC department conducts:

  • deformation tests

  • sealing and fitting tests (for lids)

  • thickness measurements

  • oven and freezer performance checks

  • visual inspection of surface smoothness

Only qualified trays enter the final packaging area.


5. Packaging & Global Shipping

We offer multiple packing options — shrink wrap, PE bags, cartons, pallet loads. Each shipment is labeled with size, capacity, and weight for clear customs and warehouse management.
We export to Europe, North America, Middle East, South America, Africa, and more.


6. Customization Services

We support:

  • OEM/ODM

  • custom mold development

  • custom thickness (30–120 microns)

  • embossed logo

  • retail packaging

Our engineering team assists clients with new product development and private-label projects.
