How to seal filterbags when sterilizing in a pressurecooker?

Hello, as the topic says i bought filter bags for the first time, usually im using rye seed jars to sterilize, but how do i sterilize rye seed in those fiter bags? I thought of using duct tape to seal the bagopening but it must stand high temperatures. How do you guys care with those filter bags, i have absolutely no other clue.
Alright sorry just found a link here on the forum but if its fully sealed it might exlode in the pressure cooker eh?

I may get yelled at, so forgive me but in new. I just use electrical tape to seal the ends. There are plenty of different ways but that's what infuse and it works fine for me. Always make sure filter patch is never covered and put a plate on top of your bags in PC to keep them from clogging the pressure valve.

Roll the top down to the filter and use metal binderclips I do this and they are great

Yup, an impulse sealer is how they're designer to be used. Roger rabbit ties a piece of wire around them like how you would use a twist tie on a bread bag. I have two impulse sealers and I don't know if they are both total shit or what, but I lose about 1/5 bags cause they don't seal properly. What's worse is you can't even tell until after you PC your grain, inoculate them, and they expand from CO2 production, then you can squeeze them and tell if there's a leak. Either it doesn't seal the whole thing if the temp is too low or it melts holes in it if it's too high. There IS no sweet spot, it's a pain in the fucking dick. I might just try wires or something myself.

Are we talking after steril or pre? pre I just fold them over until g2g, you can preseal I guess but you have to cut your bag open for no reason.

Depends on the filter on those bags. If you are .2ug then dont seal them prior to sterilization, just roll the tops over and they will form somewhat of a vacuum during the sterilization process. You will have to be gentle with them when you pull them out of the PC so that you dont break the seal on the way to your inoculation area. If you seal these bags before PCing them, the filters will be ruined.
If you have .5ug or 5ug filters, you can seal them with an impulse sealer prior to the PC cycle. Then you can cut them open, inoculate, and reseal.
.2ug and .5ug both work well for spawn production. 5ug and .5ug both work well for invitro fruiting.

Many of the 0.2s can be sealed prior, it just depends on the bag. It should tell you if you can or not where ever you get them from. ~10 years ago that was not the case, the 0.2s would all burst if you sealed them first.

Fold them to the filter and once done with PC move them to the SAB or your flowhood and zip tie, impulse seal duct tape or a million other ways you can sealt them but just make sure you do everything in a clean area.. It sucks to lose a bag full of grain

Alright thank you guys, using filter bags is so much more comfortable but the filters are kinda tricky, ill send you some pics.

If ur having trouble with cheaply made sealers, try holding it down for 5 Mississippi after the light goes off so the plastic has time to cool before opening the sealer back up. Make sure u press firmly on the handle.
If it's too hot, ull notice melting on the ends of the bags first.
They r tricky but usually there is a sweet spot between heat setting, amount of pressure your adding by pressing on the handle, and the amount of time u let it cool before letting the handle come back up.
I hated them at first cause I always got holes too, but twist ties, tape, zip ties, etc have their own downsides too
If ur getting pin holes on the seal of pre-sealed bags it's not necessarily the sealer. As the bag Cool in the PC the air is trying to push out so it can cause blowouts

I assume in my case the holes are not from the PCer because I can see where it either doesn't seal properly or melts the bags. My main issue is the point where the 4 layers meet the part with only 2 (the two folds on the side have 4 layers), there's always a tiny air gap right between there. If I turn the heat up then it seals that part but melts the rest. I do hold down with a lot of pressure for a few seconds after the light goes off too. I'm going to try replacing the element and teflon strip, but I've had this issue from day 1 and with two different sealers. I do 3-6 seals per bag too just to be sure and even with that I have considerable loss. It sucks!

Gotcha. I know exactly the area u mean cause if I get pinholes it's there too.
Sometimes turning the heat down but pressing pretty hard can work but sometimes the element just doesn't evenly heat and it does that melt/no melt shit

That could be what my problem is, a cheap element/sealer.

Try sealing them after the PC cycle and see what happens.
I have a bunch of bags I picked up off eBay from SE Mushrooms. I've damn near given up trying to work with them. There is definitely a quality difference between brands.

 unicorn bags never failed me yet. I presealed them sometimes. It is important to raise and release the pressure slowly. I had popped bags when I let the PC cool down too fast.
