摘要： The present disclosure is directed to reclosable packages comprising a front wall, a rear wall, and a closure region proximate to an outer edge of the container opposite a bottom of the container. The closure region includes a plurality of seal regions forming a continuous seal between the front wall and the rear wall across a width of the package and at least one of the seal regions is nonlinear. The closure region further includes at least one unsealed region defined between the seal regions. In some reclosable packages, the application of an opening force proximate to the closure region is operable to break the continuous seal between the front wall and the rear wall across a width of the package. The seal geometry may be tuned to adjust the magnitude of opening force required.

摘要： The present disclosure is directed to a reclosable package comprises a front wall, a rear wall, and an upper closure. At the upper closure, at least a portion of a surface of the rear wall is sealed to an exterior surface of the front wall at a first adhesion strength. According to embodiments, the application of a force greater than the first adhesion strength to the rear wall in a direction away from the front wall is operable to separate the portion of a surface of the rear wall from the exterior surface of the front wall. After, the return of the portion of the surface of the rear wall and an application of a force on the rear wall in the direction of the front wall is operable to reseal the portion of the interior surface of the rear wall to the exterior surface of the front wall.

摘要： The present disclosure relates to a multilayer stretch film comprising at least a first layer, wherein said first layer comprises a polyolefin resin. The film of this aspect of the disclosure further include at least a second layer, and a mechanochromic dye which may be in any or all layers of the film. Another aspect of the disclosure is a method of promoting optimal stretching of stretch film during a wrapping operation, which method comprises at least the following steps. A polyolefin resin is selected that has a given density. Selecting a mechanochromic dye based on its ability to agglomerate in an unstretched film made from the polyolefin resin having the given density, such that when the dye is included in the film, the unstretched film will exhibit a first color. Admixing the mechanochromic dye into a melt of the polyolefin resin. Forming a film from the admixture of the previous step. Wrapping an object using the film of the previous step, while stretching the film to a level where a change from the first color to a second color can be observed.
