1. What is color coated aluminum foil rolls?
Color coated aluminum foil rolls for food containers are special aluminum foil products used in food packaging. They are made by coating one or more layers of organic paint on the surface of aluminum foil. Here is a detailed introduction:
Characteristics
Good barrier properties: It can completely block light, gas, and other substances, effectively preventing the leakage or mixing of food flavors, improving the freshness of food, and prolonging the shelf life.
Excellent heat resistance: It can withstand high and low temperatures ranging from -20°C to 250°C.
Beautiful and decorative: It has a bright metallic luster and is compatible with all printing technologies.
Lightweight and convenient: The aluminum foil itself is lightweight, which is convenient to carry and use.
Common alloys and specifications
Alloys: Usually made of alloys such as 8011, 3003, 8006, and 3105.
Thickness: Generally between 0.04mm and 0.1mm.
Coating: It can be coated with colorless or white paint on one side and plain, colorless, white, colored paint, or printed on the other side. The coating has properties such as good adhesion, solvent resistance, friction resistance, and dry heat resistance.
2. How to choose good quality color coated aluminum foils?
Standard thickness for food containers: 0.04–0.1mm.
Check for uneven thickness (e.g., "thin spots" or "thick edges") using a micrometer. Uneven foil will:
Cause inconsistent stamping (containers may warp or crack).
Lead to uneven heat distribution (e.g., burning in thin areas during baking).
The base foil must be free of oil, dust, or oxidation (a dull, grayish layer). These impurities will:
A high-quality roll should unroll smoothly without "curl" (edges rolling up) or wrinkles.
Check Method: Unroll 1–2 meters of foil on a flat surface. It should lie flat without lifting edges.
Why It Matters: Curled/wrinkled foil causes jams in stamping machines, reducing production efficiency and ruining containers.
Test Method: Tear a small strip of foil (10mm wide) by hand. It should tear evenly without "splitting" (uneven, jagged tears).
Why It Matters: Foil with poor tear resistance will break during stamping, folding, or transportation.
For rolls with printed designs (e.g., brand logos), check for:
Sharp edges (no blurring or "bleeding" of colors).
No missing ink spots or smudges.
Ink adhesion (same cross-cut test as coating—ink should not peel).
Aluminum Foil Jambo Rolls we normally provide standard seaworthy export packaging:
Rolls are typically wrapped in protective film or paper to prevent damage during transit.
Outer Packaging:• by strong wooden boxes
Used for stability and protection during shipping.with waterproof Paper and Plastic Kraft Coverage: Ensures protection from moisture and environmental factors.
Baking and roasting: It is widely used in baking and roasting. It can prevent food from sticking to the baking tray, facilitate cleaning, and at the same time prevent the loss of food moisture and keep the food fresh and tender.
Food preservation: It can be used to make various food packaging containers, such as aluminum foil trays, lunch boxes, etc., which can effectively maintain the original flavor and quality of food and extend the shelf life of food.
Aerospace and high-speed rail catering: It is used to make printing lids for aerospace catering and high-speed rail catering, which meets the high requirements for food packaging in the catering industry.
