Provided are an airbag base cloth and an airbag including same, the airbag base cloth being a flexible and lightweight airbag fabric on which films are laminated, having good rubbing resistance after withstanding heat/wet heat, and providing excellent internal pressure retention within the airbag after sewing. The airbag base cloth according to the present invention is characterized in that at least one face of fabric is coated with a multilayer film having an adhesive layer, and the average value of the warp and weft slippage resistance in the base cloth is 350 N/2.5 cm or more.

Disclosed herein are laminated glass articles having a hard scratch resistant outer surface. In some embodiments, the laminated glass article includes a glass core layer and a glass clad layer. In some embodiments, the laminated glass article includes a glass core layer sandwiched between two glass clad layers. In some embodiments, the clad glass is selected from the group of consisting of: aluminate glasses; oxynitride glasses; rare earth/transition metal glasses; beryl glasses; and glasses containing lithium, zirconium, or both lithium and zirconium. Such glass compositions can thus be used in forming the clad layer.

The present patent application relates to a method of manufacturing a multilayered composite film comprising a step of co-extruding at least three layers (a), (b) and (c), of which the layer (a) forms an outward surface of the composite film; the layer (c) forms a surface of the composite film facing or coming in contact with a good to be packaged; and the layer (b) is disposed between the layer (a) and the layer (c). Further, the method includes a step of biaxial orientation of the composite film thus co-extruded. Therein, the layer (a) contains or consists of a thermoplastic resin. The layer (b) contains or consists of a polyvinylidene chloride (PVdC) resin. The layer (c) contains or consists of a resin, preferably sealable, in particular heat-sealable resin. Therein, any crosslinking of the composite film by means of radioactive radiation, in particular by means of beta, gamma, X-ray and/or electron irradiation, is omitted during the manufacturing of the composite film and/or thereafter.

A fiber reinforced metal composite having a metal layer and a fiber layer which are arranged in a stack, and adjacent layers are fixed by bonding; the composite has a two-layered or three-layered structure, wherein one layer is closely adhered to another layer and the thickness of the layer is from 0.6 mm˜0.9 mm. Such structure changes the structure of the existing fiber metal composite characterized by generally having more than three layers, and greatly reduces the thickness of the composite while maintaining good mechanical properties. Also disclosed is an application of fiber reinforced metal composite in the field of luggage case manufacturing, providing two preparation methods for providing fiber reinforced metal case shell with simple and available operations.

The present invention relates to an adhesive sheet laminate which comprises a substrate layer composed of a thermoplastic resin composition (A) containing a polypropylene-based resin as a main component, an adhesive layer composed of a thermoplastic resin composition (B) containing a specific thermoplastic resin (b) as a main component and having a melt flow rate of 0.1 to 30 g/10 min, and a release layer composed of a thermoplastic resin composition (C) containing a specific thermoplastic resin (c) as a main component and having a melt flow rate of 0.1 to 30 g/10 min, and which has a tensile elastic modulus of 2000 MPa or more.

The present disclosure relates to a thermoplastic film that includes a layer of thermoplastic material and a color indicator applied to the thermoplastic material. The color indicator can be configured to change color in response to a trigger. For example, the color indicator can change color (e.g., change from a first color to a second color) in response to a color change trigger, such as exposure to malodor particles, absorption of moisture, a length of time, or as a result of oxidation. In one or more embodiments, the thermoplastic film further includes an odor control component configured to mask, neutralize, or otherwise control malodors. The color indicator can change its color appearance as the odor control component performs to control any present malodors, thus signaling the performance of the odor control component.
