@Lisasali @ricky_enger Oh, so sorry to be late in responding. I was napping. Smiley anyway, you lineup the nozzle with the disc, no need to peel anything back or puncture because the disc has a hole in it. Go ahead and lay the bag flat on the counter after you fill it, but leave some headspace at the top. It may take a little longer than you think but if you hold it down with one hand and feel with the other, you'll notice that things are really getting compacted in the bag and the air is leaving!
