Vacuum aluminum as one of the most common printing film, to understand the basic performance, soft packaging plant employees necessary skills. 1. Compared with aluminum foil, the amount of aluminum is greatly reduced, energy and materials are saved, and the cost is reduced. A plurality of composite aluminum foil 7 ~ 9 μ m, and aluminum plating aluminum layer having a thickness of approximately 0.04 μ m, the consumption of aluminum which is about 1/200 of an aluminum foil, and the production speeds up to 700m / min. 2. It has excellent folding endurance and good toughness. There are few pinholes and cracks. There is no crazing and cracking phenomenon.
