After more than 100 years of historical development, driven by the wave of technological revolution, aluminum foil packaging has finally completed the transformation from aristocratic packaging to civilian packaging.
In the early 20th century, due to the limitation of aluminum smelting technology, the output of aluminum foil was extremely rare. The aluminum foil was also the most expensive packaging material at that time. It was only used for high-end packaging, and it was popular in the aristocratic class. Most of the civilians did not know. What is aluminum foil?
In 1911, the Swiss confectionery company took a fancy to the foil and made a decision: replacing the original packaging foil of chocolate with aluminum foil. It is the brave change of the Swiss confectionery company that has made aluminum foil packaging come to the fore in the world, and its superior performance has increasingly attracted worldwide attention.
In the next two or three decades, the development of aluminum foil packaging has been relatively stable until the World War II, aluminum foil packaging embarked on a fast lane. At that time, with excellent barrier and extension, aluminum foil as a military packaging material conquered governments and military personnel, and it was able to develop rapidly.
In the 1950s, aluminum paper and aluminum-plastic composite materials began to appear, and the practicality of aluminum foil was further developed. In the 1970s, aluminum foil packaging ushered in a gorgeous turn of its "career" - the maturity of color printing technology, making the appearance of aluminum foil more eye-catching and eye-catching. The development of aluminum foil and aluminum-plastic composite packaging has once again developed rapidly, and has come to the wider life of ordinary people and entered the popularization stage.
In the 21st century, the increasingly popular aluminum foil packaging has shown a competitive trend in the market, and to a certain extent has stimulated the upgrading of packaging aluminum foil materials. The first generation of aluminum foil composite paper is bonded with paper with 0.06 mm aluminum foil. The second generation of laminated paper is bonded with paper after being sprayed with aluminum through PET or OPP film. The third generation of vacuum aluminized paper is also the latest. The first generation of products, the biggest advantage compared to the previous one is that the aluminum layer is very thin, only 6.5-7 microns, and the environmental protection, anti-counterfeiting level is high, and the scope of application is wide.
