Abstract: 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.

Abstract: The present disclosure provides a process. In an embodiment, a process for producing a packaging article includes providing a body having a geometric shape and composed of a three-dimensional random loop material (3DRLM). The 3DRLM is composed of an olefin-based polymer. The body has a sleeve with opposing ends on respective opposing surfaces of the body. The sleeve extends through an interior portion of the body and has an opening at each respective end. Each opening has a closed width. The process includes providing a product having an insert shape. The insert shape has an insert width that is greater than or equal to the closed width of the sleeve opening. The process includes inserting the product into the sleeve.

Abstract: Laminate film structures including an adhesive layer having gas and moisture barrier properties are disclosed. The disclosed laminate film structures comprise films bonded together with an adhesive composition, the adhesive composition having barrier properties, e.g., controlling oxygen and/or water vapor transmission rates. The disclosed laminate film structures comprise films made from polymers and/or metallized polymers whereby the weight, thickness, and/or number of film layers has been reduced by using a barrier adhesive in place of a standard adhesive while still achieving similar barrier properties. Methods for forming laminate structures having a desired barrier performance are also disclosed, the methods comprising determining the desired barrier performance of the laminate structure, selecting a barrier adhesive, selecting two or more film layers, including at least a first film layer and a second film layer, applying the barrier adhesive on a surface of the first film layer, and bringing a surface of the second film layer into contact with the barrier adhesive applied on the surface of the first film layer, thereby forming the laminate structure having a desired barrier performance.

Abstract: Hydrophilic composite structures are made by impregnating a 3DL structure with a polyurethane foam formulation and curing the formulation to produce a foam that occupies the spaces in the 3DL structure. The composite structures have an unusually good capacity for retaining water even when under compressive forces. They also exhibit at most moderate swelling when saturated with water. The foam is useful as a layer of a water containment system such as a green roof or blue roof system.

Abstract: 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).
