After rolling, finishing, annealing and other processes, the original thickness of 230 to 280 microns of aluminum is finally "slimming" into high-end aluminum foil with a thickness of 4.5 to 6 microns.
The vigorous development of electric vehicles has driven the rapid "capacity expansion" of battery foil demand; on the other hand, high-end aluminum foil can effectively improve the preservation and moisture-proof performance of light packaging, and prolong the preservation period of food and medicines such as liquid milk.
The demand for high-end aluminum foil in the Chinese market is growing rapidly. The profit of high-end aluminum foil featuring ultra-thin, high performance and low pinhole is two to three times that of low-end aluminum foil.
Low-end aluminum foil has low technical requirements and can tolerate many defects. The high-end aluminum foil not only requires ultra-thin, but also must be flat and smooth, and has almost strict requirements on the number of pinholes on the surface of the aluminum foil.
In 2019, GSLX Aluminum Foil Technology Corporation started to develop an ultra-wide and ultra-thin aluminum foil project that is at the leading level in China.
At present, the width of the company's ultra-thin aluminum foil has been expanded from 1.5 meters to 1.89 meters.
The production process such as "rolling method of aluminum foil for high-strength battery" and "reducing non-metal pressing on the surface of aluminum foil" developed by GSLX.
