Abstract

A reclosable package has a first wall and a second wall opposite to the front wall A first zipper profile including a first interlocking member is attached to the first wall and a second profile having a second interlocking member, engageable with the first interlocking member, is attached to the second wall. A slider is positioned on the profiles for movement along the profiles from side to side of the package. Package material is provided which must be removed or ruptured to permit operation of the slider or to provide access to the package contents.
