Introduction of aluminium container foil

The use of aluminum foil as a semi-rigid container (as shown in Figure 4) to hold food has been widely adopted at home and abroad. With the continuous development of the national economy and the continuous improvement of people’s living standards, people’s health awareness has been continuously strengthened. With the promotion of environmental protection awareness, semi-rigid container aluminum foil has gradually replaced traditional foam and plastic food boxes.

Semi-rigid container foils are generally made of single zero foil, and in order to make containers of various shapes, the aluminum foil needs to be stamped and formed by a stamping method. However, without any treatment on the aluminum foil, in the stamping process, the aluminum foil will be scratched due to friction and the product quality will decrease. Therefore, the surface of the aluminum foil is coated with oil before stamping. Due to the lubricating effect of the oil, the surface of the aluminum foil is protected from being affected and the product quality is improved.

The traditional oiling method is mainly the rolling method, which is the most primitive oiling method. The use of rolling to apply oil on the surface of the aluminum foil often causes uneven oil on the surface of the aluminum foil, which makes the production in the stamping process uneven. smooth. The lubrication effect is not obvious when the amount of oil is small, and the aluminum foil will be scratched; the amount of oil is too large, which will cause various problems such as adhesion of the aluminum foil and the stamping parts.

Inspired by the steel rolling industry's anti-rust treatment method on the surface of strip steel, people began to use electrostatic spraying to spray the surface of aluminum foil. Whether it is an imported electrostatic oiling machine or a domestic electrostatic oiling machine, the effect is obviously better than that of the traditional roller-coating oiling machine. It not only spreads the oil evenly, but also saves the oil, which has been praised by many customers.
