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. Theclosure 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 isoperable 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. 本公开涉及可重新闭合封装体，其包括前壁、后壁和靠近容器的外边缘的封闭区域，所述外边缘与所述容器的底部相对。所述封闭区域包含多个密封区域，所述多个密封区域跨越所述封装体的宽度在所述前壁与所述后壁之间形成连续密封，并且所述密封区域中的至少一个是非线性的。所述封闭区域进一步包含限定在所述密封区域之间的至少一个未密封区域。在一些可重新闭合封装体中，靠近所述封闭区域施加打开力可用于破坏跨越所述封装体的宽度在所述前壁与所述后壁之间的所述连续密封。可以调整密封几何形状以调节所需的
