At present, most of the packaging materials of canned potato chips are aluminum foil cans, all-paper and food-grade aluminum foil. Its inner membrane is made of food-grade aluminum foil, which has low water permeability and oxygen permeability, avoids moisture or oxidation, and better ensures the safety of products. Moreover, it is better waterproof, moisture-proof and heat-insulating when stored, lighter in weight and convenient for turnover. After potato chips are processed, they are generally packed with aluminum foil sealing machine equipment. Put the potato chips in a paper jar, and then cover the jar mouth with an aluminum foil cover. The high temperature generated instantly when the equipment is heated will melt the aluminum foil paper contacted with the tank mouth to achieve the sealing effect.
Potato chip paper cans look like paper packaging, but they are actually aluminum foil bags. For a simple example, many biscuits packed in cartons (Oreo, mushroom powder, etc. ) When the carton is opened, it will be wrapped in a plastic bag, so that the biscuits inside will not get wet or dry when we buy it. And canned potato chips are on this floor? Plastic bags? It sticks directly to the carton. Finally, it is worth mentioning that Dr. Frederick J. Bauer invented this paper can of potato chips.

Summary: Fredric J. Baur, the designer of Pink Potato Chip Packaging Bucket, was very satisfied with his work, so he asked that the ashes be stored in this bucket after death. Later generations met this requirement, and now an ordinary urn and a potato chip bucket are placed side by side in his grave at Arlington National Cemetery in the United States.
