Food Foil Roll Jumbo 8011

Why does Food Foil Roll Jumbo need to be rolled up? What is the purpose of consolidating?

(1) The minimum thickness of aluminum foil can be rolled. At present, the exit thickness of modern aluminum foil finishing mills can reach 0.01-0.012mm, and the minimum thickness of finished aluminum foil can be obtained from 0.005-0.006mm.

(2) Double-joint rolling can withstand greater tension than single-sheet rolling, which can reduce the number of broken strips and improve production efficiency.

What are the requirements for the quality of aluminum foil rolls?

(1) The thickness of the two combined aluminum foils should be uniform, and the thickness deviation should not be greater than ±3%.

(2) Spray the double-column oil evenly on the double-column surface before rolling. If the double-column oil is not sprayed evenly, the dark side will have color difference after rolling.

(3) After the roll is closed, each side shall be trimmed to 10-15 mm, and the trimmed edges shall be free of cracks, burrs, and edge clips. The purpose of lap trimming is to cut off edge cracks, and at the same time to ensure that the width of the two double-rolled aluminum foils is the same.
