Alloy parameters of aluminum foil for chocolate packaging

Chocolate packaging aluminum foil is usually composed of aluminum and other alloying elements to increase its strength and corrosion resistance.

Например, thinner aluminum foil may provide better flexibility and packaging, but may require higher alloy strength to maintain its integrity. По същото време, thicker aluminum foil can provide better protection performance, but may require higher cost and processing difficulty.

The surface treatment of chocolate packaging aluminum foil can improve its surface quality, corrosion resistance and operability of surface treatment.

• Frosted treatment: Frosted treatment can make the surface of aluminum foil smooth, remove surface blemishes and stains, thereby improving its appearance quality and printing effect.
• Chemical treatment: Chocolate packaging aluminum foil can adopt chemical treatment methods, such as electrolytic oxidation, sulfite chemical treatment, и т.н. These chemical treatments can increase the corrosion resistance of 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. This 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 protrusions and depressions can be formed on the surface of 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.
