doubleseamed
Doubleseamed refers to the condition of a container, typically a metal can, whose lid has been sealed with a double seam. The double seam is formed when the edge of the can body (the flange) and the edge of the lid are mechanically joined by two interlocking folds that run around the circumference. This results in an outer and an inner seam that together secure the end to the body.
Manufacturing and structure: A double seaming operation uses specialized equipment with rolls and chucks to shape
Materials and applications: Doubleseamed containers are common in food and beverage packaging, especially for steel or
Quality and inspection: Seam integrity is critical to safety and shelf life. Quality control includes visual
Defects and causes: Common defects include gaps in the seam, missing or deformed folds, and seam cracks.
