Aluminum foil lunch box production process

Along with the continuous improvement of the production process of aluminum foil, the advantages of aluminum foil in the food packaging industry are more and more obvious due to its plasticity, safety and hygiene, environmental Aluminum foil lunch box has corrosion, good heat dissipation, and sealing effectiveness. In addition, they also need to meet food regulations and biological inertia, that is, do not affect the taste, do not affect the odor, do not affect the color, and comply with multiple international standards. protection and reuse. Among them, the molded aluminum foil lunch box is widely used for its convenience and portability. Aviation food and large-scale event catering supply has developed rapidly in recent years. The development of the industry has brought higher production requirements and industry standard requirements. 

Aluminum foil lunch box production process

The production process of aluminum foil lunch boxes is roughly divided into: six-step process: material exhibition → oiling → feeding → stamping forming → blanking → testing. During the production process, the aluminum foil is subjected to a pressing force of 40 to 80 tons, a stamping frequency of 1 to 2 seconds, an average production capacity of 20,000 pieces per day, and an aluminum foil lunch box with a shelf life of 2 years.
Aluminum foil lunch box shelf life: the finished aluminum foil lunch box is not directly to the consumer, and needs many intermediate links such as inventory, transportation, sales, etc., especially for many export-oriented lunch box manufacturers, only the shipping cycle consumption It takes more than two months, so the shelf life of the finished aluminum foil lunch box must be more than one year. The regulations of many European and American countries are 2 years. 

The aluminum foil lunch box is in direct contact with the food. According to the definition of the NSF organization, “H1 or 3H lubricants are suitable for those where the lubricant is easy or impossible to avoid contact with food”, so the food grade must be used in the production of aluminum foil lunch boxes. Lubricants to ensure food safety.

Aluminum foil as a material with light weight, low density, high barrier property, light blocking, UV resistance, moisture resistance, good corrosion resistance, good heat insulation, long shelf life, good ductility, flexibility and high resource recycling. Safety and environmentally friendly materials will surely become a continuous choice for perfect food packaging. According to relevant information, China's per capita annual consumption of aluminum is about 2 kilograms, about 1/10 of the annual per capita consumption of aluminum in developed countries, and 1/3 of the world's per capita annual consumption of aluminum. According to the European Aluminum Foil Industry Association, more than 70% of aluminum foil is used in various packaging products in Europe. In the United States, the ratio is as high as 75%, and the consumption of aluminum foil for packaging in Japan accounts for 70%, of which only food packaging accounts for 30% of aluminum foil consumption. According to incomplete statistics, the annual export volume of aluminum foil lunch boxes in China is about 300-500 million US dollars. This shows that the demand for aluminum foil lunch boxes and aluminum foil packaging products in the global market will inevitably be irreplaceable and sustainable.

The main application areas of aluminum foil packaging are: convenience food, aviation food, dairy products, soft drinks, tobacco products, medicines or health products, carbonated drinks / beer / herbal tea products.
