Not if the whole bag is inside the vacuum chamber.

The original proposal:

"I am going to need a chamber that is somewhere in the order of
14X14X6
inches. If I went with a chunk of pipe, that would have to be
something like 16" diameter. The down side to this would be cost and
bulk. The more empty space inside the chanber the longer evacuation
time."
