Embodiment 1
[0022] A method for producing aluminum foil for candy packaging, comprising an aluminum foil in an "O" state, the thickness of the aluminum foil is 12um, the width is 650mm, and the alloy grade of the aluminum foil is 8011 alloy aluminum foil. The method includes the following steps in sequence:
[0023] Step 1: Printing: Print the aluminum foil through a gravure printing machine, so that the surface of the aluminum foil is coated with a layer of protective varnish. The printing speed of the gravure printing machine is 120M / min;
[0024] Step 2: Embossing: The aluminum foil printed in step 1 is embossed through an embossing machine, so that the surface of the aluminum foil is pressed into patterns with fine lines and uniform thickness. The embossing speed of the embossing machine is 120M / min;
[0025] Step 3: Slitting: The aluminum foil embossed in step 2 is slit by a slitting machine. The width after slitting is 63mm, and the slitting speed of the slitting machine is 150M / min....
