Ropp bottle caps, also known as anti-theft roll caps, are closures mainly used for sealing bottles in the beverage industry. 8011 DOS oiled aluminum closures sheet are usually used as the material. The biggest advantage is paint adhesion and stretchability, ensuring the highest quality drawings and design printing. In addition, it has the advantages of high strength, good formability, corrosion resistance and good flatness. It is widely used in ROPP caps for red wine bottles and other beverage bottles.

Why do you apply DOS treatment to aluminum sheets for ropp caps?

DOS treatment is a treatment method that applies a uniform oil film on the surface of the aluminum sheet. The main functions of this oil film are:

Protection: Prevents aluminum sheets from being scratched and corroded during transportation, storage and processing.

Lubrication: Provides better lubricity during subsequent processing, reduces friction, and improves processing efficiency and product quality.

Aesthetics: The oil film can also improve the appearance of the aluminum sheet to a certain extent, making it smoother and brighter.
