8011 Al Foil Roll Food Grade
Soft Temper Aluminum Foil Rolls are often used in material packaging because of their good freshness retention, moisture resistance and corrosion resistance. 8011 Al Foil 10 Micron often produces many pinholes. Once the diameter of the pinholes is greater than 5 and reaches 1,000 per square meter, it will directly affect the quality of the packaging. Pinholes are a major indicator of the quality of aluminum foil and must be controlled within a certain range. GNEE uses the most advanced production machines to produce bright lines without pinholes.

The Fe and Si content in the aluminum foil material will directly affect the generation of pinholes. If Fe>2.5, A1 and Fe will easily form coarse intermetallic compounds. Pinholes will easily appear in the aluminum foil during rolling. As the number of Si increases, , Fe and Si will interact to form a solid compound.
The number of pinholes in the pure aluminum consumable material of grade 1060 will be far more than that of 1035 foil. This is due to the Fe and Si content in pure aluminum of grade 1035. Much higher than 1060. However, when the Ti content in the aluminum foil is >0.05, it is easy to form a hard TiB2 compound, which is brittle during rolling and can also lead to many pinholes.
As a leader in the aluminum industry, GNEE takes stable product quality, global sales network and reasonable prices as its core competitiveness. Our products are widely used in more than 70 countries and regions including the United States and the European Union.
