STRANGE FoodSaver Observation

Hi Everybody,

 

I vacuum sealed a bunch of stuff in jars today and mostly things went smoothly.

 

I tried to vac seal 4 quart jars of the little artificial sweetener packets. I really jammed them into the jars, so I guess you can say the contents were very dense. One quart jar had a square-ish shape and the other 3 were round.

 

The one square-ish jar sealed with no problem. However, the round ones simply would not. I tried all the tips and tricks that I have read about, but still no luck. Since the square-ish jar sealed, I transferred the sweetener to square jars. Success for all 3 on the 1st try!!! I even used the same lids !!! An added bonus was that I was able to cram more packets into the square jars.

 

For the other stuff that I vacuum sealed, approximately half the jars were round and half were square. I guess because these jars had “dense” contents, the shape made the difference. Outlandish, I know. Makes no sense, but there you have it.

 

So if you’re having trouble sealing, try changing the shape of the jar.

 

I hope this helps someone.

Were the round jars canning jars or mayo jars? I cannot get the mayo jars to vacuum seal, but they are fine in the water bath canner!

 

Just one of the random acts of frustration in life.

Hi Root Diggr,

 

I checked and it turns out that the jars are not canning jars. They’re not mayonnaise jars either. I don’t know what they are.

 

Thanks for clearing up the mystery.

It is because mayo jars have a thinner lip on them, plus, they are slightly rounded. A regular canning jar has a wider sealing surface and is flat.
