Abstract
A method of sealing a peelable lid () to a flange () provided within a metal can body () which involves inserting an induction coil () into the can body to primarily heat the sealing surface () of the flange, while keeping the exterior wall of the can relatively cool to avoid tin reflow and decoration degradation of the exterior wall. The induction coil is subsequently removed from the can body and a peelable lid applied to the flange, whereby residual heat in the flange aids the sealing of the lid to the flange, e.g. by allowing activation of a bonding material.
