摘要： The present disclosure provides a flexible container (10). In an embodiment, the flexible container comprises a first multilayer film (12) and a second multilayer film (14). Each multilayer film comprises a seal layer. The multilayer films are arranged such that seal layers oppose each other and the second multilayer film is superimposed on the first multilayer film. The films are sealed along a common peripheral edge (16) to form a closed chamber (18). In one embodiment, a free moving sheet of three-dimensional random loop material (3DRLM) is located the closed chamber. In another embodiment, an oversized sheet (128) of 3DRLM is located in the closed chamber.

摘要： Artificial turf system (10) including a primary backing layer (12) and a shock absorption component (20). The primary backing layer (12) has a plurality of artificial turf yarns (14) projecting upwardly from the primary backing layer (12). The shock absorption component (20) is composed of a sheet of three-dimensional random loop material 3DRLM (30). The sheet of 3DRLM (30) is in contact with the primary backing layer (12). The shock absorption component (20) includes (i) a cushioning layer (40) and (ii) a shockpad (50). The 3DRLM (30) in the cushioning layer (40) has an apparent density that is greater than the apparent density of the 3DRLM (30) in the shockpad (50).
