<p>A vapor resistant closure including a closure mechanism, for example, a zipper having a start end in an inner portion of material and a stop end in an outer portion of material with the outer portion containing the stop end overlapping the inner portion containing the start end. The closure mechanism forming a seal between the outer portion containing the stop end and the inner portion containing the start end when the closure mechanism is closed at the stop end. The seal that is formed is generally impermeable to fluids, gases, vapors, aerosols and particulates. The vapor resistant closure may also include a compressible body between the outer portion of material containing the stop end and the inner portion of material containing the start end. The compressible body is compressed therebetween when the closure mechanism is closed at the stop end.</p> |
