A fire extinguishing device is for a motor vehicle. The fire extinguishing device includes an internal cavity containing a pressurized fire extinguishing fluid. The cavity is delimited by a wall, the wall having at least one barrier layer (b) containing a semi-aromatic polyamide composition (B).

A degradable EVOH high-barrier composite film, characterized in that the materials of various layers in the composite film all obtain approximately-consistent biodegradability by introducing biomass, and the additive amount of the additive master batch in the materials of each layer is controlled within the range of 0.3-15% of the total mass of the materials of the corresponding layer; the hydrophilic activity of the hydrophilic groups in the additive master batch should be greater than or equal to that of the hydrophilic groups in the materials of each layer; by adding the additive master batch, the mole ratios of the hydrophilic groups to carbon atoms of the materials of various layers tend to be consistent, namely, the bioactivities tend to be consistent, so that the degradation rates of the materials of various layers in the composite film tend to be consistent. The present invention makes contribution to obtaining approximately-consistent bioactivities and approximately-consistent biodegradation rates by balancing the mole ratios of the hydrophilic groups to carbon atoms in the materials of various layers, and the appearance, the functions and the physical and mechanical properties of a product remain unchanged.

A method of manufacturing an article comprises etching an etched feature on a surface of a first polymeric sheet, and forming a fluid-filled bladder element from the first polymeric sheet, with the fluid-filled bladder element having a sealable internal cavity that retains fluid. The method includes assembling the bladder element in the article so that a first portion of the bladder element having the etched feature is exposed to view, and a second portion of the bladder element is blocked from view by the article. An article includes the bladder element with the etched feature.

The invention discloses a paperboard for packaging of a heat-sealable packaging material comprising: —a paperboard substrate comprising a first and a second side, —a first and an optional second dispersion coating layer on the first side, which first and optional second dispersion coating layer provides a barrier against at least one of liquid, moisture, grease and gas, —an extrusion coated barrier layer comprising a polyolefin, wherein the first and optional second dispersion coating layer is applied between the paperboard substrate and the extrusion coated barrier layer, and wherein the coat weight of the extrusion coated barrier layer is less than 15 gsm. The packaging material according of the invention minimizes the amount of plastic coating, but still provides the needed barrier properties for the packaging of food and/or liquid. The packaging material has especially been shown to provide a longer shelf life for food items packed in a packaging made from the material. Especially, the packaging material provides gas-, liquid and/or grease barrier properties. Although the packaging material comprises such low amount of extruded thermoplastic polymers, the material is readily heat-sealable.

Floor coverings having a greige good, an adhesive layer, and a secondary backing material. The greige good has a primary backing component having adjoined first and second portions, and a plurality of fibers. The secondary backing material has an attached portion and a first exposable portion, with the attached portion adhered to the first portion of the primary backing component by contact with the adhesive layer. The second portion of the primary backing component is unattached to the first exposable portion of the secondary backing material, and the first exposable portion defines a portion of the first end edge of the floor covering. The second portion of the primary backing component is selectively moveable relative to the first portion to a position in which at least a portion of the second portion of the primary backing component does not overlie the first exposable portion of the secondary backing material.

A laminated pre-applied membrane is provided. The membrane comprises a layer of polyethylene and a rubber or rubber-based layer.

A flexible, sterilizable pouch includes a first gas-impermeable web, a second gas-permeable web, and the third gas-impermeable web. The webs are arranged and sealed to form a cavity portion of the pouch and a header portion of the pouch. The header portion of the pouch is gas-permeable through the second gas-permeable web. The cavity portion of the pouch is configured to hold a medical device for sterilization and is configured to be sealed from the header portion after sterilization, thereby making the cavity portion gas-impermeable. The header is also configured to be removed from the pouch, leaving the cavity portion.

Proposed are a laminated anodic aluminum oxide structure in which a plurality of anodic aluminum oxide films are stacked, a guide plate of a probe card using the same, and a probe card having the same. More particularly, proposed are a laminated anodic aluminum oxide structure with a high degree of surface strength, a guide plate of a probe card using the same, and a probe card having the same.

The present disclosure is directed to articles such as bladders comprising mechano-luminescent materials which emit light when the mechano-luminescent materials are placed under stress. The present disclosure is also directed to articles including these bladders, methods of forming these bladders, and methods of making articles including these bladders.

A packaging material for the formation of packaging containers comprising at least a base layer having a hole and at least one separation element covering the hole. The hole extends within a plane being defined by a longitudinal axis and a transversal axis orthogonal to the longitudinal axis. An imaginary longitudinal line parallel to the first longitudinal axis and an imaginary transversal line parallel to the transversal axis mutually intersect at a center point of the hole. A first maximum extension of the hole along the imaginary longitudinal line is larger than a second maximum extension of the hole along the imaginary transversal line. The hole is asymmetric with respect to the imaginary transversal line.
