Pre-oiled alu foil for punching various containers, commonly used alloys 8011, 3003, 3004, 1145, etc., with a thickness of 0.02-0.08mm and a thickness of oiled 150-400mg/m2.
The use of alu foil as a semi-rigid container for food storage has been widely used at home and abroad. With the continuous development of the national economy and the continuous improvement of people's living standards, people's awareness of health is also continuously enhanced, and People's awareness of environmental protection has increased. alu foil has gradually replaced the traditional foam and plastic food boxes.
3003 h24 aluminium foil prelubricated is generally made of single-zero foil, and to make containers of various shapes, the alu foil must be sealed and formed by stamping. However, without any processing on the alu foil, during the sealing process, the alu foil will be scratched due to friction and the product quality will decrease. Therefore, the surface of the alu foil is oiled before sealing, and the lubricating action of the oil can protect the surface of the alu foil from the impact and improve the product quality.
The traditional lubrication method is mainly roller coating, which is the most primitive lubrication method. The use of roller coating to lubricate the surface of the alu foil often causes uneven oil on the surface of the alu foil, resulting in uneven production during the stamping process. . The lubricating effect is not obvious if the amount of oil is small and the alu foil will be scratched; if the amount of oil is large, it will cause various problems such as adhesion between the alu foil and the sealing parts.
Inspired by the anti-rust surface treatment of strip steel in the rolled steel industry, people began to use electrostatic spraying to spray the surface of alu foil. Whether it is imported electrostatic oil or domestic electrostatic oil, the effect is obviously much better than that of traditional roller oil. It not only coats the oil evenly, but also saves oil and has been well received by customers.
