| Alloy series | 1000, 3000, 8000 series aluminum alloy |
| Alloy state | H18 or H19 hardened state |
| Alloy composition | pure aluminum containing more than 99% aluminum, and other elements such as silicon, copper, manganese and magnesium, etc. |
| Thickness | 0.007mm-0.2mm, according to the needs of chocolate packaging |
| Width | according to the requirements of the chocolate packaging machine |
For example, thinner aluminum foil can provide better flexibility and packaging, but may require higher alloy strength to maintain its integrity. At the same time, thicker aluminum foil can provide better protective properties, but may require higher cost and processing difficulty.
surface treatment
The surface treatment of chocolate packaging aluminum foil can improve its surface quality, corrosion resistance and surface treatment operability.
Matte treatment: Matte treatment can smooth the surface of aluminum foil and remove surface defects and stains, thereby improving its appearance quality and printing effect.
Chemical treatment: Chocolate packaging aluminum foil can use chemical treatment methods, such as electrolytic oxidation, sulfite chemical treatment, etc. These chemical treatments can increase the corrosion resistance of the aluminum foil and protect its surface from corrosion and oxidation.
Coating treatment: Coating treatment can protect the surface of chocolate packaging aluminum foil by applying a protective film. The coating can be an organic coating, such as polyamide or polyester, or an inorganic coating, such as aluminum oxide.
Calendering treatment: Through calendering treatment, uniform small ridges and depressions can be formed on the surface of the aluminum foil, thereby improving its surface gloss and printing performance.
These surface treatment methods can be selected and applied according to the specific requirements and production process of chocolate packaging.
We can produce aluminum foil rolls for chocolate according to your requirements. We also supply aluminum foil sheets for chocolate.
