💡 How does electro magnetic induction heating fuse aluminum foil liners to plastic caps?
Buyers trust this thermal bonding method because it cuts the daily grind without messing up workflow.
- You slide the metallic disc into the cap before screwing it down tight
- A high frequency coil blasts power through the thread wall in two seconds
- The inner tacky layer liquefies and clings to the jar lip upon cooling
- Tamper rings stay glued firm so customers can spot a breach quick
