Aluminum foil lunch boxes can be divided into single-sided lightweight aluminum foil lunch boxes and double-sided lightweight aluminum foil lunch boxes according to their surface conditions. Aluminum foil lunch box rolls are divided into single rolls and double rolls.
(1) Single-sided light aluminum foil lunch box: When double-rolled, only one side of each aluminum foil is in contact with the roll. The surface in contact with the roll sleeve and the side in contact with the aluminum foil are different in brightness. The surface in contact with the root is bright, and the contact surface between the boxes is black. This kind of aluminum foil lunch box is called a single-sided light aluminum foil lunch box. The thickness of a single-sided light aluminum foil lunch box usually does not exceed 0.3mm, but with the improvement of user requirements and manufacturer equipment capabilities, the thickness of a single-sided light aluminum foil lunch box can reach 0.05mrno
(2) Double-sided light aluminum foil lunch box: The upper and lower surfaces of a single-roll aluminum foil lunch box are in contact with the roller, and both sides have a bright golden luster. This kind of aluminum foil is called a double-sided light aluminum foil lunch box. The minimum thickness of the double-sided light aluminum foil lunch box mainly depends on the diameter of the working silver, which is generally not less than 0.01mm.
Aluminum foil lunch boxes (aluminum foil containers) have the characteristics and advantages of safety and hygiene, high and low temperature resistance, green environmental protection, renewable energy saving, and good sealing.
Disposable aluminum foil lunch boxes (disposable aluminum foil containers) inherit the various advantages of aluminum foil lunch boxes and gradually enter thousands of households. As the world's aluminum foil producer and exporter, my country's aluminum foil production and processing technology and equipment have reached the world level, and the quality of disposable aluminum foil lunch boxes has also reached the international level. However, the domestic aluminum foil packaging application market is still sluggish, and the sales of aluminum foil lunch boxes and containers have been poor. With the gradual decline in the price of aluminum raw materials and the continuous improvement of production and processing technology, the current price of aluminum foil lunch boxes is very close to qualified plastic lunch boxes and degradable lunch boxes. In addition to the advantages of recyclability and environmental protection, cost performance is the outstanding value of aluminum foil lunch boxes. With the gradual understanding of the public about aluminum foil, more and more people pay more attention to their own health and environmental protection, and aluminum foil lunch boxes are becoming more and more popular and recognized by everyone.
