    • Three-dimensional polymeric article (100) having first (101) and second (102) opposed major surfaces, a base body (103) having a first dimension, a second dimension perpendicular to the first dimension, and a thickness, wherein the thickness is orthogonal to the first and second dimensions, wherein the base body (103) comprises a plurality of alternating, adjacent first (107) and second (108) polymeric regions along the first dimension, wherein the second dimensions of the first (107) and second (108) regions extend at least partially across the second dimensions, wherein the first regions (107) have a first crosslink density, wherein the second regions (108) have a second crosslink density, wherein the second crosslink density of the second regions (108) are less than the first crosslink density of the first regions (107), wherein the first and second regions extend perpendicularly in two directions from a central plane (115) in the base body (103) parallel to the first and second dimensions of the polymeric article (100), and wherein the second regions (108) extend in each of said two directions further than does the first regions (107). Embodiments of the three-dimensional polymeric article described herein are useful for providing a dual sided, textured wrapping film such that greater grip is realized both on an item wrapped by the film and the wrapped item itself.
    • 具有第一(101)和第二(102)相对主表面的三维聚合物制品(100),具有第一尺寸,垂直于第一尺寸的第二尺寸的基体(103) 和厚度,其中所述厚度与所述第一和第二尺寸正交,其中所述基体(103)沿着所述第一维度包括多个交替的相邻的第一(107)和第二(108)聚合物区域,其中所述第二尺寸 所述第一区域(107)和第二区域(108)至少部分地延伸穿过所述第二维度,其中所述第一区域(107)具有第一交联密度,其中所述第二区域(108)具有第二交联密度,其中所述第二 所述第二区域(108)的交联密度小于所述第一区域(107)的第一交联密度,其中所述第一区域和所述第二区域从所述基体(103)中的中心平面(115)沿两个方向垂直地平行延伸 到第一个 和第二尺寸,并且其中所述第二区域(108)比所述第一区域(107)更向所述两个方向中的每个方向延伸。 本文描述的三维聚合物制品的实施方案可用于提供双面带纹理的包装膜,使得在由膜包裹的物品和包裹的物品本身上实现更大的抓握。
