Flexible extrusions of selected die patterns may be slid or snapped together to create bundles of slidably-interlocked extrusions that may be used to create structural components for architectural and a plurality of other construction purposes. Components such as standard rectangular construction beams, arches, domes, architectural trees, cylinders, molds, puzzling mazes, furniture, rollercoaster track, and other applications are illustrated and described in embodiments herein. Bundles of slidably-interlocked extrusions may be formed into a straight beam, bent into an arch, or twisted into other forms as desired. Bundles of slidably-interlocked extrusions may for example, comprise subsets of different length bundles of extrusions that may extend the length create long-span support beams or that may branch away at an angle from the starting beam to form a treelike structure.

A method for producing a laminate, the method comprising at least a pretreatment step of pretreating a surface of a substrate made of a plastic film by reactive ion etching so that the maximum displacement of the substrate surface measured by local thermal analysis is 300 nm or more, and a lamination step of laminating a thermoplastic resin layer made of a material different from that of the substrate on the pretreated surface of the substrate; wherein the plastic film is a polyethylene terephthalate film.

A coextrusion head for manufacturing a bicomponent polymer fiber, comprising a first inlet for receiving a core polymer component, a second inlet for receiving a cladding polymer component, and a dual-channel nozzle comprising an inner channel and an outer channel encompassing the inner channel. The inner and outer channel are in hydraulic connection with the first and second inlet, respectively. The dual-channel nozzle further comprises a joining path establishing a hydraulic connection between the inner channel, the outer channel, and a nozzle outlet of the dual-channel nozzle. The joining path is adapted for bringing the core polymer component and the cladding polymer component into contact with each other such that a contact layer comprising a mixture of the core polymer component and the cladding polymer component is formed between the core polymer component and the cladding polymer component.

Provided are a wiper for a machine tool and a method for manufacturing a wiper for a machine tool, which can simplify a manufacturing process. A wiper for a machine tool mountable on a machine tool includes: a wiper body fixable to the machine tool, and made of a first elastic material having hardness of 80 degrees or more; and a sliding part made of a second elastic material containing a particulate reinforcing material and having hardness in a range of 50 degrees or more and 90 degrees or less which is smaller than the hardness of the first elastic material, the sliding part being provided integrally with the wiper body, wherein the wiper body and the sliding part are integrally formed without an adhesive.

The present disclosure is directed to peelable, heat-sealable lidding films for containers of diverse polymer compositions storing various products such as foodstuffs and pharmaceuticals. The lidding films disclosed herein can be heat-sealed to crystalline polyester trays (CPET), easily peeled, and contain improved antifogging performance by incorporating a non-migratory antifogging additive into the heat sealable layer of the film without deteriorating seal strengths.

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.
