The characteristics of the can material of the milk powder can making machine

In the process of making milk powder cans with milk powder can making machines, the selection and characteristics of the can material directly affect the safety, durability and production efficiency of the product.

Non-toxic and harmless:
The material of the milk powder can must be non-toxic and harmless to ensure that it will not release harmful substances when it comes into contact with milk powder. Common food-grade materials such as aluminum alloy, stainless steel and high-density polyethylene meet this requirement. These materials need to undergo food safety certification, such as FDA certification or European Food Safety Authority standards, to ensure that they meet the safety requirements of food packaging materials. The chemical stability of the material is crucial because unqualified materials may react chemically when in contact with milk powder, resulting in the release of harmful substances or changes in the quality of milk powder.

Corrosion resistance:
Milk powder may contain a small amount of acid or other chemical components, which requires the can material to have excellent corrosion resistance. Aluminum alloy and stainless steel are widely used materials because they can effectively resist corrosion and oxidation and maintain long-term structural stability. In particular, aluminum alloys can significantly enhance their corrosion resistance after surface treatment.

Moisture-proof performance:
Milk powder needs to be kept dry to avoid caking or deterioration. Therefore, the can material must have good moisture resistance. High-density polyethylene and aluminum foil composite materials are often used to manufacture milk powder cans because of their excellent moisture resistance. These materials can effectively block the intrusion of moisture and ensure that the milk powder remains dry during storage.

Mechanical strength and durability:
Milk powder cans need to withstand certain pressure and impact during transportation and storage, so the material must have sufficient mechanical strength. Aluminum alloy and stainless steel are widely used in milk powder can production due to their high strength and impact resistance. These materials can effectively resist physical impact and prevent the can from breaking or deforming.
