Product Introduction
Bottom ends are metal can components used as the base closure of a can body. They play an important role in supporting can strength, maintaining sealing performance, and protecting the packed product during filling, storage, and transportation.
Unlike easy open ends, which are designed for opening convenience, bottom ends are developed with greater focus on structural stability, secure attachment, and reliable bottom sealing. They are widely used in food cans, beverage containers, and other metal packaging applications where stable can structure and dependable sealing are required.
A typical bottom end is designed to provide stable attachment and structural support for the can base. It generally includes:
End panel
Curling / seaming edge
Reinforced profile for strength
Protective coating layer
The structure is engineered to ensure strong seaming performance, maintain base integrity, and support the can during stacking, storage, and transportation.
