An article may include a first polymeric material layer having a surface. A first conductive trace may form at least a portion of the first layer surface. The article may further include a second polymeric material layer. The second layer may have a first surface, a portion of the second layer first surface being bonded to a portion of the first layer surface. The second layer may have a portion of a channel defined therein, the channel at least partially coinciding with a portion of the first conductive trace. The article may also include a first patch interposed between the first layer surface and the second layer first surface. The first patch may span the channel and cover a portion of the first conductive trace.

An apparatus for thermally joining thermoplastic fiber composite components includes a pressurization arrangement for jointly covering, at least in a region of a joining zone, thermoplastic fiber composite components to be joined and applying pressure to the thermoplastic fiber composite components to press the thermoplastic fiber composite components against one another, at least in the joining zone, the pressurization arrangement being flexible, at least in some section or sections. A welding device is configured for welding the fiber composite components in the joining zone during pressurization. The pressurization arrangement and welding device are configured to weld the thermoplastic fiber composite components in a pressurized state in the joining zone. The pressurization arrangement is configured to maintain pressurization independently of the welding device until the joining zone solidifies. A cover is also disclosed for a pressurization device for thermally joining thermoplastic fiber composite components.

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 tamper evident card package includes a first portion comprising plastic polymer and defining a cavity extending from a base surface of the first portion. A second portion comprises a flat sheet of plastic polymer joined to the first at a seal extending around an entirety of a perimeter of the tamper evident card package, where the first portion and the second portion form a unitary structure at the seal. An insert contained between the first portion and the second portion includes a point-of-sale activated card and machine readable activation information for the point-of-sale activated card from an exterior of the tamper evident card package.
