Abstract: The reclosable plastic bag is formed by opposing panels of web with four sides sealed. A zipper is sealed within the bag so that a first zipper profile is sealed to a first opposing panel and a second zipper profile is sealed to a second opposing panel. A slider engaging the zipper profiles in a closed position protrudes from an opening in at least one of the opposing panels and may be further secured in place by a label. The slider cannot be moved from the position wherein the zipper profiles are closed to the position wherein the zipper profiles are open prior to the user tearing a perforated or otherwise weakened line across the panels. When this tear is made, it is unmistakable and intuitive evidence that the bag may have been previously opened and depending upon the circumstances, possibly tampered.

Abstract: The method of forming a tamper-evident plastic bag or similar container includes providing a zipper with interlocking first and second profiles with respective first and second flanges. The second flange is longer than the first flange. A distal portion (with respect to the interlocking elements of the profiles) of the second flange is sealed to the web thereby forming a transport seal to carry the zipper with the web through a form, fill and seal machine. At the form fill and seal machine hard seals are formed between the web and the first flange and a proximal portion of the second flange. The transport seal is a peel seal or alternatively the second flange is formed with a frangible section between the distal and proximal portions and the transport seal is a hard seal. In both cases the second flange provides tamper evidence and/or a hermetic barrier for the completed bag.
