A polyethylene-based thermally-shrinkable film for pack-in box packaging, in which: a product is not damaged due to breakage or looseness of a film during packaging and transportation of the product; because of the low-temperature shrink characteristic, the product is not exposed to excessively high heat during shrink wrapping and power consumption in a shrink tunnel can be reduced; and because of a small thickness of the film, garbage and other wastes can be reduced. The film is a polyethylene-based thermally-shrinkable multilayer film for pack-in box packaging obtained by biaxial orientation in MD and TD and stretching in MD only further after biaxial orientation. Preferably, the film is a polyethylene-based thermally-shrinkable multilayer film for pack-in box packaging in which the film as a whole has a thickness of 25 μm or less.

An aseptic pillow packaging bag and a laminated resin film that can be preferably used to produce the packaging bag. The laminated resin film includes a center layer that has a first surface provided with an inner surface layer, and a second surface provided with an outer surface layer. In the laminated resin film, the inner surface layer is a first multilayer film made of linear low density polyethylene, including two or more films selected from C6L-LDPE and/or C8L-LDPE, the center layer is a nylon-based film, or a barrier nylon film, and the outer surface layer is formed by laminating a medium density polyethylene film onto a low density polyethylene film or a medium density polyethylene film with a nylon film interposed therebetween.

The present invention is directed to a thermoplastic packaging film coated with an antimicrobial coating, a method for the preparation of the coated film and packaging articles made with the film.

A flexible, fibrous energy managing composite panel includes multiple flocked energy absorbing material (FEAM) layers separated by dividers. The FEAM layers can be single side or double side and can be fabricated from monofilament fibers having different properties (e.g., length and denier) flocked onto various substrates. The dividers can include sheets, fabrics, films, foam, spacer fabrics to separate the flock fibers in adjacent layers. The composite panels can be processed for breathability and flexibility. Other embodiments include piezoelectric FEAM layers and dividers for electronic sensing applications, and application of composite panels to body armor and the outer shells of helmets.

A metallized film capacitor includes: a metallized film columnar body including two metallized films that are laminated and wound, the two metalized films each including a vapor-deposited metal film with a plurality of vapor-deposition-free slits and fuse portions each interposed between the vapor-deposition-free slits, and a polyvinylidene fluoride dielectric film, the metallized film columnar body having two electrode extraction surfaces; metal-sprayed parts disposed respectively on the two electrode extraction surfaces: and outgoing terminals joined respectively to the metal-sprayed parts. Each of the two metallized films has a shape with successive sloped ridges and valleys in a cross-section orthogonal to a winding direction, and the two metallized films are laminated such that the ridges and valleys of one of the metallized films are aligned with the ridges and valleys of the other one of the metallized films.
