Flat Sealing Head

Ideal for sealing most containers with a liner close to the top of the cap
& for caps with diameters of more than 53mm.

When discussing any sealing head style it is important to remember a few important concepts:

  • 1 The strength of the electromagnetic field generated by your induction sealer dissipates exponentially with respect to the distance from the sealing head.
  • 2 The distance from the top of your cap to the foil inside the cap is not equal with all closure styles. Compare a flat continuous thread (CT) cap with a child resistant closure (CRC.) The foil in the flat CT cap is very near the top while the foil in the CRC maybe as much as 1/4" from the top of the cap!
  • 3 The physical size of the foil inner liner plays a role in determining which style of sealing head works best for your application. While it may seem a little counter-intuitive at first thought, it takes more energy to seal a smaller liner than it does a large one because as the liner increases in size, it also increases the amount of metal mass available to be heated.

Every application may vary a bit, but as a general rule containers with caps greater than 53mm in diameter where the foil is near the top of the closure are typically sealed utilizing a flat sealing head. The magnetic field produced by the sealing head is directed into the foil from the head above. 

Enercon also offers a tunnel sealing heads and a special sealing head known as our All-in-One sealing head which allows you to seal a range of closures from 24mm up to 120mm all with the same sealing head.

Our application experts are available to provide you advice on which sealing head is best for your application.
