A package integrity feature for a recloseable package is provided. The recloseable package may be made from a laminate film and may comprise a scored inner layer having a machine direction and a scored outer layer laminated together with both permanent adhesive and pressure sensitive adhesive to form a recloseable flap that covers an opening in a package body. The package integrity feature may be a strip of material cut into the inner layer of the laminate film in such a way that the strip breaks when the package is opened, leaving one end of the strip attached to the package body and the opposite end attached to the recloseable flap.

Package integrity feature for recloseable package

A reclosable package is described that includes a package integrity feature defined by an inner film layer of the package. The package integrity feature includes a first die cut portion and a second die cut portion that both extend from a main die cut portion at least partially defining the opening of the package. The first and second die cut portions are continuous with each other and with the main die cut portion, such that they are defined by a single cut line. In some cases, the package integrity feature includes a neck region that tears when the package is opened and an anchor region that resists delamination. Because the first and second die cut portions are continuously formed with each other, the anchor region may have a circular or elliptical shape and is, thus, easier and more consistently manufactured, allowing for better performance.

Disclosed are methods and compositions of films using selected blends of primary and secondary fatty amide additives at critical ratios, which enable the primary fatty amides to interact favorably with the secondary amides so as to provide controlled COF and other useful surface properties in polyolefin and other films.
