Dry lubricationis a kind of raw material which is used to produce aluminum foil containers without lubrication oil. As we all know, the heavy metal in aluminum foil will do harm to the human body, while this special material specifically solves this problem. Meanwhile, the traditional aluminum foil is produced with the stamping oil, which will influence the shelf life. The dry lubrication is environmental, recyclable and biodegradable.
