A tamper-evident package utilizes a transparent resealable adhesive structure such as a tape or a label to cover the closure opening. Upon a first opening of the package frangible portions of the package front between adjacent arcuate cuts and slits defining the opening are torn. This tearing distorts the packaging film so that re-registration of the opposing lateral edges upon reclosing is not possible. This results in a package which is visually tamper-evident. The tamper-evident condition can be enhanced by graphics or other printing on the front of the package in the area of the closure to make the misalignment of a resealed closure viewed through the transparent structure more visually apparent. In one embodiment of the invention a series of arcuate cuts are centered laterally and are flanked on the right and left sides by two continuous wavy slits which form a portion of the closure opening.

Tamper-evident, tear-open resealable package

A re-closable, stand-up package with a tamper-evident opening system. Production of the package originates from only two feed rolls. One roll is a flexible film web and the other is an adhesive tape. A reclosing layer is constructed from a strip of web material taken from a side of the feed roll and a length of the tape. The strip portion of the closure layer is perforated along tear lines which define a package opening. The tape and the strip are then adhesively joined so that they partially overlap vertically. The closure layer is then applied to the web over a slit in the front panel forming a re-closable primary opening. A gusset fold at the bottom of the package permits the package to be free-standing vertically upright. Contents of the package can be dispensed only after rupture of the closure layer strip.
