Aluminum tin can and tinplate metal tin cans are common packaging containers, and they have different characteristics in some aspects. Here's how they compare:
Material: Aluminum cans are made of aluminum alloy, while tinplate cans are made of tinned or coated with internal anti-corrosion layer of iron. Aluminum cans are lighter, while tinplate cans are heavier.
Corrosion resistance: Aluminum cans have good corrosion resistance because aluminum has its own oxide layer, which can prevent further corrosion. Tinplate cans require internal anti-corrosion treatment to prevent food or liquid from coming into contact with iron and causing corrosion.
Sealing performance: Aluminum cans and tinplate cans can be sealed design, effectively protect the freshness and quality of packaging items. However, because aluminum cans have a better oxidation layer, they may be slightly better than tinplate cans in terms of oxidation resistance and air tightness.
Recyclability: Aluminum cans and tinplate cans are recyclable materials. They can both reduce resource waste through recycling and reuse processes and have less impact on the environment.
Cost and Use: Aluminum cans are relatively common and widely used in the packaging of beverages, food and other consumer goods. Tinplate cans are common in some specific applications, such as canned food, cosmetics, and chemicals.
To sum up, there are some differences between aluminum cans and tinplate cans in terms of materials, corrosion resistance, sealing performance, recyclability and use. The selection of the appropriate tank type should take into account the characteristics of the product and the packaging requirements.
