In an embodiment, a heat-seal film includes 10-90 wt % of a first polymer component and 10-90 wt % of a second polymer component, based on a total weight of the first polymer component and the second polymer component, wherein: the first polymer component includes propylene, and optionally, up to 18 wt % of a C.sub.2 and/or a C.sub.4-C.sub.20 α-olefin based on a total weight of the first polymer component; and the second polymer component includes 91-99.9 wt % of propylene and 0.1-9 wt % of ethylene based on a total weight of the second polymer component, the second copolymer component having a melt flow rate of 2-60 g/10 min. In another embodiment, a multi-layer film structure includes a heat-seal layer including a heat-seal film described herein; and an unoriented, an uniaxially oriented, or a biaxially oriented base layer including polypropylene homopolymer, a polypropylene random copolymer, or a combination thereof.

Disclosed herein is a technique for further improving the quietness in a vehicle cabin while reducing an increase in the weight of a motor vehicle. A noise reduction member, arranged in a fender inner space defined between a fender panel serving as an exterior panel for a motor vehicle and an inner fender forming a wheelhouse, includes a pair of wall portions which are made of a foamed material and arranged to be spaced apart from each other.

A thermal vacuum insulation element (10) comprising a first planar limiting part (12) and a second planar limiting part (14). The limiting parts are spaced apart from each other and define an evacuated space (16) between them. The evacuated space (16) is sealed by means (26) for sealing. The vacuum insulation element includes first support elements (18) extending away from the first limiting part (12) into the evacuated space (16) and second support elements (20) extending away from the second limiting part (14) into the evacuated space (16), the limiting parts (12, 14) being arranged with the support elements (18, 20) such that the first support elements (18) and the second support elements (20) protrude beyond and are spaced from each other. The first support elements (18) are spaced from the second limiting part (14), and the second support elements (20) are spaced from the first limiting part (12). A fiber structure (22) interconnects the first support elements (18) and the second support elements (20). The fiber structure (22) has a low thermal conductivity and is configured to absorb at least the pressure caused by the vacuum on the first and second limiting parts (12, 14).

A method for manufacturing an alveolar core structure includes at least one cell including a secondary duct having a first end defining a sound wave inlet, and an opposite second end, the secondary duct comprising a sound wave outlet. The method also includes a fastening step in which adhesive tapes transverse to the longitudinal direction of said first plate are applied on a first longitudinal plate. The secondary duct in the form of a flattened element is fastened, on the first plate, by gluing at its sound wave inlet. A second plate is applied. A step of deploying the first and second plates so as to form the peripheral wall of the cells and so that the flattened element is deployed.

A display device includes a cover window including a curved portion, and a panel member laminated on the cover window. A method of manufacturing a display device includes mounting a cover window including a curved portion on a first jig including a curved portion, mounting a panel member on a second jig that conforms to a surface of the first jig, and laminating the cover window to the panel member by moving a first one of the first jig or the second jig to a first other one of the first jig or the second jig. An apparatus for manufacturing a display device includes a first jig including a mount surface that is partially curved to conform to a surface of a cover window, a second jig including a surface conforming to the mount surface and configured to contact a panel member, and a driving unit.
