ABSTRACT:
A tamper-evident reclosable package having a header that is tack sealed to the zipper. A light tack, in the form of a light weld, is made at the end of the package header. The header is the top portion of the package and is designed to shroud the zipper. The header serves as a tamper-evident feature, and also serves to maintain cleanliness and aesthetics of the package. The header must be tom before a person can gain access to the contents of the package. Typically, means for preferential tearing are provided for easy removal of the header. The tack seal contributes to the maintenance of the cleanliness and aesthetics of the package, while still allowing easy removal of the header. The tack is light (i.e., low bond strength or pull-off force) in order to not make it significantly more difficult to open the package.
