The present disclosure relates to liners and methods of making liners. The liners may be suitable for use with tanks and other storage/containment vessels, such as process tanks, immersion tanks, indoor or outdoor containment pits, gravity feed conduits (e.g., concrete trench, canal, or drain, etc.) for transferring or conveying liquid, grain storage tanks or containers (e.g., dielectric or electrically non-conductive liners for grain storage, etc.), etc.

A tube (10) and a method of constructing such a tube, the tube (10) being in the form of a composite film structure comprising a co-extrusion of a plurality of layers bonded together to provide an integrated structure. The layers comprise an inner layer (11), an intermediate layer (12) and outer layer (13). The intermediate layer (12) is of a material compatible with two adjacent layers (11, 13) between which it is interposed, wherein the intermediate layer (12) provides a bridge between the two layers (11, 13) to provide the tube (10) as an integrated structure. The exterior surface (15) of the tube (10) is optionally treated or modified or is provided with a coating, typically for bonding with another substance such as a resinous binder. A hollow structure in the form of a tubular element configured as a pipe and constructed using the tube (10) is also disclosed.

Embodiments of the invention provide a facer used as protective covering for an insulation product. The facer may include a metallic foil layer, a scrim layer, and a paper layer positioned adjacent the scrim layer. The facer may also include a polypropylene material forming a polypropylene layer positioned adjacent the paper layer and heat bonded to an exposed major surface of the paper layer such that a portion of the polypropylene extends into pores of the paper layer to assist in coupling the polypropylene material to the paper layer.

Methods of applying a paint film on a substrate may include adhering a corner patch on at least a portion of a corner of the substrate and adhering a paint film sheet on the substrate such that the corner is within a corner relief pattern of the paint film sheet. The corner relief pattern may correspond to a recess along an edge of the paint film sheet. The paint film sheet may partially overlap with and bond with the corner patch, thereby providing a continuous paint film over at least the corner of the substrate. Cosmetic paint films configured for adhering onto an exterior panel of a motor vehicle are also provided.

Disclosed herein are exemplary embodiments of linings, liners, and methods of providing a liner or lining for a tank. An exemplary embodiment includes a method of providing a liner or lining for a tank. In this exemplary embodiment, the method includes extrusion welding a pair of sheets together by infusing a molten thermoplastic material along an interface and within a gap between the pair of sheets. The method also includes extrusion welding the pair of sheets to a bottom sheet by infusing the molten thermoplastic material along and between the pair of sheets and the bottom sheet.

Devices, methods and systems disclosed herein relate to the application of a protective film on a surface of an electronic device that instantly reduces air bubbles and eliminates the waiting time usually required when using a wet fluid solution. In one embodiment, a roller apparatus may be used to apply the protective film on the surface of the electronic device. The roller apparatus may include an opening for receiving a display peg.
