What are the advantages of aluminum foil? It is of strong air barrier performance, strong mechanical properties, high blast resistance, strong puncture and tear resistance, high temperature resistance (121℃), low temperature resistance (-50℃), oil resistance and good fragrance retention performance.
What are the quality requirements for cigarette aluminum foil? In the production process, the control of surface and performance mainly includes the following points:
1. Control the quality from the source and strictly inspect the blanks.
2. During the rolling process, the surface quality is controlled by the cleaning and roughness control of the rolls, the selection of rolling oil, reducing the viscosity of the rolling oil, and controlling the operating speed of the machine,etc.
3. During the slitting process, ensure that the edges of the aluminum coil are neat during slitting, and there should be no quality problems such as the curling edge.
4. In the annealing process, the annealing time and annealing temperature are controlled according to the performance requirements of the cigarette foil to ensure clean degreasing.
