发明名称 Tamper-evident package and method to make such a package
摘要 A reclosable package (10) for the retail display of a food product and for the purchase and storage thereof by a consumer has tamper-evident features to enable the consumer to discern whether the package has been opened prior to purchase. The package (10) includes a header (26) formed by attaching the front and back sheets (12,14) of the package (10) to one another above the interlocking profiles (20,22) of the zipper (18) of the package (10) with a peel seal. Below the interlocking profiles (20,22), the front sheet (12) has a line of weakness (32), such as a line of perforations extending transversely across the package (10) below the interlocking profiles (20,22). A tear in the line of weakness (32) or a breach of the peel seal would readily indicate that the integrity of the package (10) has been compromised.
