The "three-piece can" is an important type of metal packaging container, named for being composed of three independent parts: the can body, the can lid, and the can bottom. It is a widely used packaging form in industries such as food, beverages, and chemicals. Its core feature is that the structure is clearly disassembled, and each component is connected through a specific process, which can adapt to the packaging requirements of different contents. It is especially widely used in scenarios that require good sealing and pressure resistance.

• ✓
  Strong sealing performance The double-rolled edge process can achieve high air tightness and high water tightness, which can isolate oxygen and moisture, and extend the shelf life of the contents (for example, canned food can be stored at room temperature for 1-2 years).
• ✓
  Wide material compatibility Materials such as tinplate and aluminum alloy can be selected based on the characteristics of the contents (such as acidity, oiliness, and high pressure) to avoid chemical reactions.
• ✓
  Flexible processing The height and diameter of the can body can be flexibly adjusted, suitable for small-batch and multi-specification orders (such as from 50ml condiment cans to 5000ml industrial raw material cans).
• ✓
  Cost control The production equipment is mature. During large-scale production, the cost is lower than that of some irregular-shaped packaging, and the metal materials can be recycled and reused.
