Okay I give up... where the **** are the raw autoclavable bags?! Where do myco suppliers get them from?!

To preface, I know there are countless myco-suppliers selling pre-made bags w/ filter patches, but what I am looking for is the raw rolls of tubing which I can seal on the ends to make custom-sized bags.
So I know most plastics are incompatible with pressure cooking/autoclaves. At 250 deg F/120 C, the most common plastics used for bags (e.g., HDPE and LDPE) will simply melt or leech toxic chemicals into their contents.
As far as I know, polypropylene (PP) is the only relatively safe plastic that can be used to manufacture PC/autoclave-compatible bags. But for the life of me, I cannot find 4-8" wide tube rolls of PP bagging material.
There are countless suppliers selling 500-1000' rolls of LDPE/HDPE tubing that can be used to make custom-sized bags, but I can't find a SINGLE one that sells rolls of PC/autoclavable tubing.
Where are the myco-suppliers getting their bag materials from?! Is it some industry secret? I've posted online elsewhere, got no answers, and even some suppliers are hesitant to tell me where.
I found one listing on Amazon for PP bag tubing (here: https://www.amazon.com/1000-Crystal-Clear-Polypropylene-Tubing/dp/B07CMGWSK5), but in the "Questions and Answers" section, it states they cannot be used in pressure cooking for some reason.
Does anyone have any answers? Where do I get the raw tubing to make bags? Do you think the product from Amazon linked above will work, despite the person claiming otherwise (it wasn't the seller who said "no").

Found some here: https://www.uline.com/BL_5581/Crystal-Clear-Tubing
Looks about the same as the Amazon product.
Can anyone confirm if 2-mil polypropylene bags will survive a pressure cooker?

Wouldn't gourmet growers making logs at scale be steaming, rather than pressure cooking? Perhaps what you want just straight up doesn't exist.

Just looking to replace my jars for producing grain spawn. Much easier to break up grain inside a bag than in a jar.
And it would be way cheaper to get a roll of plastic tube for 70 or 80 bucks, enough to make 800-1000 bags, than to buy 25 pre-made bags for 10-20 bucks.

Hi all, first post.. hope everyone is enjoying some Fall weather and all that it promises.
I'm going to jump right in and necro bump this thread because I too, am trying to determine if 2 mil PP tubing has been used effectively as a spawn bag. Kaival, did you get some and try this in a PC? There is some 12" x 1000' 2mil by Tapelogic on amazon for $57. Yes, one thousand feet. That's about 8Β’/bag and I'll DIY patches all day long for that kind of price break.
But alas.. it's only 2 mil. I've scoured for 3 and 4 mil everywhere and just coming up dry. Someone is manufacturing this but it just doesn't show up online. Anyone tried this? Thanks in advance!

Im prettu confident that food vacuum storage bags will work. They can handle boiling temps so they should be able to handle a PC cycle.

When I was last active on here like 5 years ago I remember seeing vendors sell them, because I was going to go that route myself. I do remember them having the rolls.

Standard Unicorn bags are 2.2mil. They have a thick version of some models in a 3.0mil thickness. The 3.0 bags don't always seal well with a 5ml sealer if the gussets are folded in.
What are you planning on using for GE?

Do you mean 3-4 mil rolls? That would be really helpful. I haven't been on this forum in so long that my account vaporized, like 2007.

Possibly micropore, but I haven't gotten that far yet. I have several cubic feet of P100 fabric that would work well too. Quote:

You want this you will have to contact a plastic manufacturer. It's not a common off-the-shelf product. They probably wont talk to you unles you want a whole 40 ft container of it but you never know.
Common poly bags on a roll are polyethylene. The common true PP bags are this "crystal clear" type that do hold up to the PC but it's not really the same PP product that Unicorn uses obviously, much crisper/firmer. And I have only found it available as flat smaller bags never rolls.
Unicorn is using a special PP mix. He probably has a relationship with an Asian plastic manufacturer for the raw material rolls.

Someone on amazon replied that the 2 mil works, so I'm probably going to give that a shot.
If it doesn't, I can always make a 500 foot tall tube man with my blower.
