The foil back in a honeycomb design is made by lamination machines. They only glue the honeycomb when combining the foil and paper. Thus, the foil and paper will have many spacings. So why use the honeycomb on the foil back?
- The interspace of the honeycomb pattern could lock the heat of the wrapped food, keeping it hot longer. At the same time, aluminum foil has a good insulation effect. Thus, the honeycomb foil wrapper is a perfect package for sandwiches and other takeaway food.
- The normal foil-backing paper structure is aluminum foil and paper. If you combine the foil and paper with full glue, the foil paper will not be as soft as the honeycomb foil. The foil wrapper with honeycomb is easier to wrap for food.
- A foil wrapper with honeycomb is cheaper than foil paper with full glue.
