When was aluminum foil officially used in the packaging industry?
Aluminum foil packaging began in the early 20th century, when aluminum foil was still an expensive packaging material used only for high-end packaging. In 1911, a Swiss candy company started using aluminum foil to package chocolates, gradually replacing tin foil and becoming popular. In 1913, the United States also began producing aluminum foil based on successful aluminum refining, but it was only used for high-end goods, life-saving supplies, and chewing gum packaging.
In 1921, the United States successfully developed composite aluminum foil paperboard, mainly used as decorative panels and high-end packaging for folding paper boxes. In 1938, heat-sealable aluminum foil paper was introduced. It was not until the period of World War II that aluminum foil as a military packaging material saw rapid development. In 1948, molded aluminum foil containers were used for packaging food. In the 1950s, aluminum foil and aluminum-plastic composite materials began to develop. By the 1970s, with the maturity of color printing technology, aluminum foil and aluminum-plastic composite packaging entered a period of rapid popularization.

How do bosses deal with waste aluminum foil?
With the rapid development of the aluminum foil industry, aluminum foil recycling has also become an aspect that the industry must pay attention to. Aluminum foil recycling generally has two methods: door-to-door recycling and unified recycling at waste stations. Since waste aluminum foil is mostly used for food packaging and combined with other materials, the recycling process is relatively complicated. The general method is to classify and recycle it, and then have it effectively utilized by professional processing organizations. Some can be used as input for new production processes, while aluminum foil and other waste that cannot be used are partially converted into auxiliary fuels, and some are sent to landfills or undergo incineration at waste treatment plants.
After reading these, do you have a deeper understanding of aluminum foil? I hope the bosses have a new understanding of aluminum foil boxes.
