@pastrygirl, I have a quasi-professional Weston vacuum sealer which uses textured vacuum seal bags. When the machine is engaged to vacuum seal a bag, the air in the bag is vacuumed out. Anything soft might get crushed during that vacuuming. There is a Manual button which is supposed to stop the vacuum from sucking any more air out of the bag. It is, however, somewhat unreliable.
For a long time I've been looking for an inexpensive non-chamber vacuum sealer which seals when the user wants it to.
