ACV: Spout Pouch Vacuum Bags?

Hey Community,
I was wondering if anyone new of a spout pouch bag that would work well in a chamber vac the ACV?

I often make batches of sauces and marinades that I would like to home package in spout bags to aid in usability. Chamber vac sealing the bag would also help with life stability.

What I am thinking of ideally is a spout bag similar to the attached photo that could still be sealed in the ACV.

Thoughts, ideas?
