The foil is cut into square after grid-like paper or aluminum foil printing. It is mainly used for packaging various instant food, such as hamburgers, sandwiches, hot dogs, etc.
The biggest advantage of this composite is that there is air in the grid between foil and paper. It expands after heating to insulate heat and keep warm. Meanwhile, the paper absorbs moisture and keeps the freshness of bread. The foil is oil resistant to prevent oil spills and keep the hands clean.
Different patterns and colors can be printed to customer’s requirement to make it convenient for users to distinguish different foods.
