Zip tied salami developing air pockets after 1 wk

Here’s my take on it.

The bags are “plastic” so there should not be any shrinkage like a natural casing would due during the phase.
Since the bags release the moisture out and not back in, no problem except looks.

If wanted one can place into a vac sealer to “srink or pull it closer”, but as the chub dries further the same thing is going to happen.
