Air-Cooled
Refers to induction sealers which do not require water to cool the induction sealing head.

Eddy Currents
Currents induced in the body of a conducting mass by a variation in magnetic flux.

Electromagnetic Field
The field of influence produced around a conductor by the current flowing through it. These are sometimes referred to as flux lines in the design of a sealing head.

Ferrite
Dense homogeneous ceramic structures made by mixing iron oxide (Fe203) with oxides or caronates of one or more metals such as manganese, zinc, nickel or magnesium. They are used in induction sealing systems to direct the electromagnetic field into a desired direction.

Induction Heating
The method of producing heat by subjecting a material to a variable electromagnetic field. Internal losses due to circulating eddy currents in the material cause it to heat up.

Kilowatt
Kilowatt is a measurement of power and was once the primary unit used to measure the sealing power of induction sealers. With the advent of air cooled cap sealers and improvements in power supply and sealing head designs kW no longer provide an accurate basis of comparison of sealing units.

Line Speed
Line speed may be defined by containers per minute (cpm) or feet per minute (fpm). FPM measures conveyor speed and provides a more relative number when determining the required strength of an induction field to achieve a seal.

Pilferage
Refers to product theft. Induction seals deter pilferage by making it difficult to quickly open a package.

Power Supply
One component of an induction sealer. The power supply supplies power to the induction sealing head which generates the induction field required to seal containers.

Sealing Head
Part of the induction sealer which emits the induction field to heat the foil liner.

Single Piece Liner
The most common type of liner used. When applied to the container mouth it provides a hermetic seal with no residual part of the liner left in the cap.

Static Losses
A term to indicate the amount of power required to operate the power supply at any given output setting. It relates to the amount of power consumed by the Sealing Head, Power Supply and other elements to function when no bottles with liners are present. Each bottle passing under the sealing head will consume additional power (losses) that collectively will add up to the maximum power capability of the power supply.

Tamper Evident
Something that provides evidence that a package has been previously opened. To achieve tamper evidence there must be evidence left behind even if the tamper-evident device has been removed from the package.

Tunnel
Term used to describe a type of sealing head in which the cap travels through a tunnel that directs the induction sealing field to the induction liner.

Two Piece Liner
This type of liner provides a hermetic seal with one piece of the liner and leaves a residual liner piece in the cap as an extra barrier.
