Can "Canning" be achieved with "vacuum sealed" bags? Upon reading the question If I vacuum seal a food product like beef stew then boil it in the bag, would it keep un-refrigerated? and the answer provided https://cooking.stackexchange.com/a/69423/6279 I agree that 'normally' it would not result in making something shelf stable. But My question is COULD you (by putting the vacuum sealed bag into a pressure cooker) achieve the results of canning in said bag? I found some speculation on this question here but I am unsure of the conclusion...(given the sources)
(disclaimer: I've only heard of people doing this, not done it myself.)

Yes, it can be done. You're looking for retort pouch canning. Various places will sell you the bags, and you can vacuum seal them with a chamber vac, though you may need an upgraded heat bar. Then you can process them in a pressure canner (or preferably autoclave).

I'd definitely follow the normal reheating recommendations (the boil it 10 minutes bit) before eating. I don't think USDA has home canning guides for retort pouches.
