Alu Foil Jumbo Roll 7 Micron For Flexible Packaging

Alu Foil Jumbo Roll 7 Micron For Flexible Packaging is commonly used for material lamination and flexible packaging. Alloys include 1235, 8011, 8079. This application requires stringent surface finish and strength. Please be careful when buying, don't just look at the price, also check the TDS to make sure the brush is level and the pinhole goes through. We can provide aluminum foil thickness from 0.0053-0.2mm and width from 50-1730mm. Alloys include 8011, 8079, and 1235, which are widely used in the packaging material industry, containers, composite materials, electrical engineering and electronics, and printing.

Its production process:
Smelting: The primary aluminum is converted into molten aluminum through a large-capacity regenerative smelting furnace, and then enters the casting and rolling mill through the launder. Form a continuous and uniform refining effect. Form a continuous and uniform cleaning effect.
 
Rough rolling: The molten aluminum in the first step is introduced into the casting and rolling mill to form a billet.
 
Intermediate rolling: The slab is rolled to a thickness of 4.5mm again by a cold rolling mill, and then sent to an annealing furnace, heated at 360 °C for 2 hours, and heated at 580 °C for 18 hours for uniform annealing to make the grain size uniform and the direction consistent. Then continue cold rolling to 0.60mm in the cold rolling mill, and send it to the annealing furnace again. After heating to 460°C for 5 hours, cooling to 400°C for 7 hours for intermediate annealing. Then continue to roll into aluminum foil cotton with a thickness of 0.3mm;
 
Rolling foil: The above-mentioned 0.3mm aluminum foil wool is rolled into an aluminum foil product by a four-roll irreversible foil rolling mill. The production process of ultra-thin aluminum foil is short, the operating cost is low, and the production investment is small, and the quality of the ultra-thin aluminum foil produced can reach the most advanced international level.7 Micron Alu foil for Lamination Grade Application.
