Induction sealing is the process of bonding thermoplastic materials by induction heating. This involves controlled heating an electrically conducting object (usually aluminum foil) by electromagnetic induction, through heat generated in the object by eddy currents.
Induction sealing is used in many types of manufacturing. In packaging it is used for package fabrication such as forming tubes from flexible materials, attaching plastic closures to package forms, etc. Probably the most common use of induction sealing is cap sealing, a non-contact method of heating an inner seal
to hermetically seal the top of plastic and glass containers. This sealing process takes place after the container has been filled and capped.

    Sealing olives

    There seem to be a few camp on compression fittings, some people just fit an olive, others olive with PTFE tape and a third group olive and paste. I’ve never bothered with tape etc and never had an olive leak. Are the other options a DIY thing or are people taught one to the olive + tape etc?
