Why GNEE Aluminum as the supplier for heat sealing foil?
GNEE has all the equipment needed to produce aluminum foil, including a rolling mill, winding machine, roll grinder, annealing furnace, thick and thin shears, and thin foil shears. Aluminum foil with a thickness of 0.005-0.2mm and a width of 20-2000mm can be supplied in a variety of specifications.
The rolling mill for aluminum foil has a highly stable, fully hydraulic setting. The finishing mill's maximum speed is 1200 m/min, while the coarse and medium rolling mill's maximum speed is 2000 m/min. Aluminum foil with a width of 1850–2000 mm can be sliced using the slitting machine.
With high-performance tools like vacuum and automatic surface quality testing for aluminum foil, online surface quality testing reports, and pinhole testing reports for the full length of aluminum foil goods, zero defect delivery is achieved.
