Teach Soap

Just a tip for you. I didn't really believe this would work, but I tried it and it worked really well.

I was having a problem with a batch of pots. The design isn't 100% right for pressure-sensitive liner seals and we were having seal failures. Not a disaster, because the new preservative system is holding up well, but I had to either junk 250 pots/lids or come up with an answer.

I was at a factor for my industry and I noticed they had the aluminium style liner seals so I asked if I could have some samples.
"Have you got an induction heater?"
Me: "Huh?"
An induction heater for those who don't know, can cost about $150 up, it releases a pulse of electromagnetic energy that heats up the aluminium disc seal, which gets glued to the rim, and simultaneously melts the wax in the pulpboard backing to release the seal from the backing, which gets retained in the lid usually.

Anyway, smiling grimly the salesperson gave me half a dozen of these seals.
I proceeded home and placed one on top of the rim of a pot, and used the wife's electric iron set pretty damn hot. In about a second, it made a perfect seal. So, in an emergency, you can make them work if you have an iron.
I will be buying an induction sealer because I think it makes a more professional seal than the pressure-adhesive foam ones.

Did you ruin her iron??

No, it doesn't do any harm to the iron. It only takes a second or so for each pot.

I have not seen the aluminum seals available in smaller quantities here in the US. Right now, I use the pressure sensitive seals.
