There are two processes for covering kraft paper on the surface of aluminium roll:
First: The kraft paper used on the surface is self-adhesive bonded by glue, which has the advantages of high production efficiency, timely delivery and low production cost.
Two: The kraft paper and aluminium roll are bonded together by heating.
After covering kraft paper, the aluminium roll can be further processed to make embossed aluminium roll.
