Wooden case packing could guarantee the quality of the materials during transportation and storage.

All stacks of the aluminum sheets are bound firmly in nylon, and respectively fixed in wooden cases.

The twist off lid is usually made by tinplate before. However the tinplate is easy to rust, which has bad visual effect and may have an impact on the food.
