The Manufacturing Process of Aluminum Foil Jumbo Roll
As one of the commonly used materials in flexible packaging, aluminum foil jumbo roll has its unique advantages. The manufacturing process of jumbo roll aluminum foil can be divided into simple processing and deep processing.
Simple processing
The aluminum foil blank is a cold-rolled aluminum coil with a thickness of 0.4-0.7mm and a high multiple deformation rate. The aluminum foil blank is first quenched at 240-480°C, and then sent to the steel roller with high hardness and high finish.
After rough rolling, intermediate rolling and finishing rolling, the aluminum foil blank will be turned into the aluminum sheet and finally be quenched to get aluminum foil. The thickness of the aluminum foil can be controlled by adjusting the tension, the rolling force during rough rolling, and the speed during finishing rolling.
During finishing rolling, the thickness of the foil decreases as the rolling speed increases; the greater the tension, the smaller the thickness. This kind of aluminum foil that has not undergone other processing is called plain foil.
Deep processing
1. Compounding
Laminate aluminum foil with plastic film, paper, cellophane, etc. with adhesives or PE to form composite films for various purposes.
2. Coloring
The aluminum foil can be displayed in various colors on the coloring machine. With its own metal luster, the decorative performance will get greatly improved.
3. Printing
Aluminum foil can be printed directly, or printed on the surface after coating. The printed aluminum foil jumbo roll has better decoration effect.
4. Embossing
The aluminum foil can be used to emboss various patterns on the embossing machine, which is used to wrap food with a good decorative effect. Aluminum foil embossing can also improve its surface flatness and eliminate its slight wrinkles.
