摘要： A package includes a patch and a packaging film. The patch comprises a support and a sealing layer comprising chlorite ions. The support is permeable to chlorine dioxide. The packaging film has an inner surface defining at least a portion of an interior space of the package for housing an article. The packaging film is substantially impermeable to chlorine dioxide and is transparent to ultraviolet light. The patch is affixed to the inner surface of the packaging film by the sealing layer. Chlorine dioxide may be generated by subjecting the package to ultraviolet (UV) light such that the UV light reaches the sealing layer of the patch to convert the chlorite ions to chlorine dioxide.

摘要： A resealable package includes a first edge and a fin seal. The first edge defines a boundary between two panels. The first edge may be removed to separate the two panels to access contents within the package. The fin seal extends across one of the two panels in a direction parallel to the first edge. The fin seal includes an adhesive region and a film that includes a removable portion located over at least a portion of the adhesive region. The fin seal is configured to allow resealing of the bag by coupling the adhesive region to one of the two panels.

摘要： Resealable packages having a pressure sensitive adhesive (PSA) layer that is fully integrated into the packaging film and a removable portion easily accessed by a peel tab at the edge of the package, adjacent to a score. Removal of a portion of the package exposes the pressure sensitive adhesive layer and allows for access to the product in the package interior. The package is easily resealed by folding the exposed pressure sensitive adhesive layer to adhere to the outer surface of the package.

摘要： Heat-seal condition indicating packages include a first sealing substrate comprising a leuco dye and a second sealing substrate comprising a leuco dye developer. The packages may optionally include a leuco dye sensitizer which dissolves both the leuco dye and the leuco dye developer when melted. The packages further include a heat-seal produced between the first sealing substrate and the second seating substrate. The heat-sea! comprises a reaction product of the leuco dye and the leuco dye developer. The reaction product may be colored, which may provide the heat-seal with a detectable optical characteristic. A magnitude of the optical characteristic may be proportion to the strength of the seal between the first and second seating substrates.

摘要： The present invention is directed to packages having a peelable/resealable tamper-evident label adhesively sealed to the portion of packaging body with a line of weakness. The peelable/resealable tamper-evident label comprises an unsealed pull tab and a plurality of adjacent tear slits positioned at or near the periphery of the peelable/resealable tamper-evident label. The tear slits are slanted towards the unsealed pull tab. The packages provide evidence of tampering when one Improperly attempts to open the package by removing the label at a corner or a side of the label. When the label is lifted anywhere other than the unsealed pull tab, it will tear at one or more tear slits which indicates that the label has been tampered with.
摘要翻译： 本发明涉及具有可剥离/可重新密封的防篡改标签的包装，该标签通过弱线与包装体的该部分粘合密封。 可剥离/可再密封防篡改标签包括未密封拉片和位于可剥离/可再密封防篡改标签的外围或附近的多个相邻撕裂狭缝。 撕裂缝朝向未密封的拉片倾斜。 如果不正确地尝试通过移除标签角落或侧面的标签来打开包装，则包装会提供篡改证据。 当标签被抬起时，除了未密封的拉环以外，它将在一个或多个撕裂缝处撕裂，这表明标签已被篡改。
