plastic lids
    #26966554 - 10/02/20 07:23 PM (3 years, 4 months ago)

has anyone used the lids in the link below before? ive seen them on on myco shops. they definably dont leak but there is no rubber seal. its def safe fin the PC as its plastic #5(Polypropylene). i did a quick test with some in the PC just to be sure and they survived just fine stayed rigid(plastic didn't soften from heat) ive just never seen these before and a little worried about the lack of a rubber seal.

I have used plastic lids for a long time without a rubber ring with no contams, though the lids in your link state that they aren't good for canning (or microwaving). I would advise against those particular lids.

I use the very same, and they work great! Just finished loading up some jars just now actually.

ran into an issue with these lids, i used high temp silicone and it stuck to the plastic but i was easily able to peel it off. does anyone else use high temp silicone with the plastic lids or a different glue?

the silicone comes off the metal lids too but not with as much ease as the plastic. wondering if the pressure that build up in the jars when cooking will push a small opening in the glue. ive had this happen with some sprinkler pipes as i didn't have PVC and tried to get away with what i had, silicone. once the pressure built up in the hose the silicone came right off.

check the expiration for the silicone. i had a tube that worked great for over a year and then never set recently.

I use 16oz jars with plastic lids stuffed with polyfil. I buy them at the grocery store they usually have garlic or something in them. So I just empty them out wash them and stuff the lid with poly and I have jars that I can get locally and are cheap.

I've never had any problem with the Ball leak proof I have dozens of them modded but I actually like these better.

https://www.amazon.com/gp/aw/d/B083GV6LS8?psc=1&ref=ppx_pop_mob_b_asin_title

They're ugly AF but they're cheaper and the silicone ring makes them super easy to get the lid off and still leak proof. Even with wet ISO gloves.

I use these plastic lids:

https://www.amazon.com/dp/B076VTY6XS/ref=cm_sw_r_cp_api_i_gr.EFb29VK2ST

I also had a problem with the silicone peeling off easily but you just need to scuff up your lid with sandpaper so the silicone can grip the surface better. I remade all my lids and they work very well now. Could help to let your silicone set for a little bit before PCing, although the PC will also apparently speed up the curing process.

@Grimsweepeer, do those not warp at all from PCing? Would love to get plastic one piece lids that can be PC’d and don’t leak for LI.

thanks JHOVA, i checked the expiration date and it the silicone is still good. im thinking of using some epoxy putty, kind of over kill but its waterproof and can handle 300F and 1500PSI(overkill again). looking for a better alternative tho casue these lids kick ass, i fucking hate the metal.


thanks Grimsweeper. unfortunately i saw those or some similar in a LC lid post here after i bought the ball lids. those are a much better deal. next round for sure.

thank Lenz good idea with sanding, dont know why i didn't think of that, just figured it would hold well. maybe ill try that.

I've used the Aotzi colored lids, white Wal-Mart MainStays lids, and I'm currently using those Ball leak-proofs for my LC

I tried doing unmodded lids using the white MainStays and colored Aotzis. Based on my experiences, the white MainStays are much more airtight than the Aotzis

I say this because I experienced a VERY long colonization time, probably due to insufficient GE. Eventually they all did get to 100% after opening them up slightly

The Aotzis feel a bit flimsier than either the MainStays or the Leak Proofs, but I'm satisifed with them anyway. So every brand of plastic lid I've tried so far has worked fairly well for me

The ugly ones with the silicone ring feel a but more flimsy than Ball Leak Proof like the white mainstay ones do but when they come out of the PC warm they hold up well. I'd trust them with LC, the mainstay I wouldn't.

Update:

So last night i decided to run some experiments with the silicone glue and the ball lids. I sanded the area that needed glue down as Lenz suggested. But i also hate the 3-4 hour cure and 24 hour full cure time so i ran my hear gun over them to see how the glue would react to heat. i figured the silicone only dries when the nasty vinegar smelling stuff is all evaporated out of the silicone. the outer layer dried nicely so with that going well i tossed them into a pyrex baking dish and threw them in the oven at 180F for 20-30min and when they cam out they were practically ready to go and cured, super dry and hardened. i would let them sit a cool for a a bit before using them tho.

The sanding seemed to help too as the glue isnt coming off as easy as before.

also had some great ideas for filters i will share soon once i put the ideas to the test!

The gray Ball lids are polypropylene which is resistant to steam autoclaving (pressure cooking). I asked about them last year when they first started showing up on store shelves, then got some myself.

That roughly coincides with it being done curing, but that's not what causes it to cure. RTV (room-temperature vulcanizing) silicone reacts with moisture in the air and releases acetic acid (that vinegar smell) during the curing process. In case you were wondering...

So you had a good experience with these gray lids so far? They keep their shape after numerous PC cycles? I'm just wondering since in the description it is specifically indicated that: "Not for use for home canning". I really would like to get away from the metal 2-piece lids...

I think that disclaimer is there more so to avoid getting sued if someone gets botulism or something for attempting long-term preservation of foods with those jar lids. I assume the seal is not as air-tight as that of a metal gasket

The grey lids are great - the white ones at walmart not so much.  I use the 29mm SFD's embedded into the melted plastic around the hole for my grain jars.  I've never had one come off.

These lids have been cycled 5 or 6 times so far and still look like new.

@ sporecap. Yes ive run a few tests and the plastic stays hard i think they are pretty good lids. i ran them for a solid 3 hours no prob/ they do say not to use them in a PC but they are made of plastic # 5 (polypropylene) has a melting point of 320F and i believe the PC doesn't get much hotter than 280F

i first discovered these on a myco shop. (link below)

https://mycosupply.com/product/plastic-canning-jar-lids/

i first purchased these white lids(link below), not knowing they were not for canning and ended up looking for a buying the gray lids.  but there is a good LC lid tek on here that i came across after buying  the gray lids and see that the ones i originally bought would have probably work. the white lids are a much softer plastic and i actually like the gray ones better. even tho the gray ones are leak proof i decided to get the silicone rings to make a better seal.

im waiting on some teflon tubing and will be making some GE filters with. Ill post once i have a finished product.

@ PBJ710

How do you melt the filter disc to the lids? that sounds pretty awesome. what material are the discs you use made from?

The cheap white ones are okay. That's about it. I still use them if I run out of superior lids but I wrap them like a petri if I have to use them.
