🔍 TECHNICAL INSIGHT: DOUBLE SEAM IN RECTANGULAR CANS

Did you know that forming a reliable double seam in rectangular containers is much more challenging than in round cans?

The corners of rectangular packages create uneven material flow during seaming, generating higher stresses and increasing the risk of defects such as wrinkles, false seams, or insufficient overlap. This makes precise control of seaming parameters, tooling condition, and container geometry essential.

A high-quality double seam must ensure:
✅ Hermetic sealing
✅ Adequate overlap between body and end hooks
✅ Correct seam thickness and tightness
✅ Consistent performance across straight sides and corners

Understanding the behavior of the seam in rectangular packaging is critical for maintaining product integrity, food safety, and shelf life.
