A flexible plastic film reclosable package for foodstuffs or the like, comprising in combination: opposed plastic film walls joined at their edges to form a plastic bag with a bag mouth between the walls at one side; fastener strips between the walls and the bag having reclosable pressure interlocking rib and groove profiles joined to close the bag with base webs supporting the profiles and laminated to the inner surface of the film; peel seal means for sealing the space between the profiles and for maintaining the profiles in the interlocking relationship until the peel seal means is broken so that the bag is initially sealed against contamination, and after opening the profiles provide a reclosable bag; and a protector in the form of a loose flap extending from said rib profile and positioned with the plastic film walls between the contents and the interlocking profiles.
