Abstract
A fastener strip comprising a reclosable portion including an elongated first backing, including a trough extending lengthwise along the first backing and an elongated second backing, including a ridge extending lengthwise along a second backing, the ridge removably insertable into the trough to essentially prevent air flow across the trough, and a generally planar portion including essentially no ridge and essentially no trough, and a plug that joins the ridge of the reclosable portion and the trough of the reclosable portion at the adjacent end of the reclosable portion to the plug in an airtight seal that prevents air from leaking from the adjacent end of the reclosable portion.
