A method of making a sandwich-type composite panel having a cellulose-based core and a living hinge from a stack of material is provided. The stack includes first and second reinforced thermoplastic skins, first and second sheets of thermoplastic adhesive and a cellulose-based cellular core disposed between the sheets and the skins. A pressure is applied to the stack after heating the stack wherein the skins are bonded to the core by the sheets to form the composite panel. A portion of the composite panel is crushed at a predetermined location simultaneously with applying the pressure to locally compact and separate the cellular core at the predetermined location to form two side portions of the panel. The heated first skin stretches during the step of crushing while remaining intact between the two side portions. The skins bond together at the predetermined location to form the living hinge.

An optical element includes a substrate, a plurality of reflective reflection layers on the substrate, and an absorbing layer over the reflection layers. The reflection layers are arranged in a striped manner in plan view. The absorbing layer absorbs polarized light oscillating in the direction in which the reflection layers extend. The optical element also includes an oxide film on the substrate between the reflection layers and on the absorbing layer. The oxide film is formed by oxidizing the absorbing layer.

A flexible packaging laminate is formed to have a built-in opening and reclose feature by forming the laminate as a two-part structure having an outer structure joined in face-to-face relation with an inner structure. Score lines are formed in both structures to enable an opening to be formed through the laminate by lifting an opening portion (e.g., a flap or the like) of the two structures out of the plane of the laminate. The score line through the outer structure defines a larger opening than the score line through the inner structure, such that a marginal region of the outer structure extends beyond the edge of the opening portion of the inner structure. A pressure-sensitive adhesive is used to re-adhere the marginal region to an underlying surface of the inner structure adjacent the opening through the laminate.

To easily process a concave groove, properly form the concave groove, not worsen fittability, and improve diffusion of body fluid.

A method of manufacturing an absorbent article in which an absorbent body (4) is provided between a liquid permeable topsheet (3) and a backsheet (2), an absorbent body concave portion (20), which is a concave groove or a slit, being formed at a skin-contacting side including a body fluid expelling area (H) along a longitudinal direction of the absorbent body without using compression, and an embossed portion (21) being formed in the absorbent body concave portion (20) along the absorbent body concave portion (20) by embossing from a top surface side of the liquid permeable topsheet. The method includes a first step of forming the absorbent body (4) provided with the absorbent body concave portion (20); a second step of forming core embosses (23) at least on both sides of the absorbent body concave portion (20) by compressing the absorbent body from the skin-contacting side of the absorbent body (4); and a third step of stacking the liquid permeable topsheet (3) on a top surface side of the absorbent body (4) and forming the embossed portion (21).

A gasket (13) for use in a medical syringe is provided, which includes a main body (14) made of an elastic material, and a lamination film (15) provided on a surface of the main body (14). The gasket (13) has a circumferential surface portion (17) to be kept in contact with an inner peripheral surface of a syringe barrel (11) of the syringe. The gasket (13) has a groove (22) provided in the circumferential surface portion (17) thereof as extending circumferentially thereof. The groove (22) has a depth of not less than 0.8D (m), preferably not less than D (m), wherein D (m) is the thickness of a portion of the lamination film (15) present in the circumferential surface portion (17) of the gasket (13).

Method for producing a weakened decorative composite from at least one decorative material (25) and a spacer fabric (11), in particular for producing coverings of airbags in motor vehicles, which spacer fabrics (11) have an upper cover layer (12) and a lower cover layer (13) and a layer (15) having spacer threads (14) is located between the cover layers (12, 13), wherein the weakenings in the spacer fabric (11) are blind holes (16) which are introduced into the lower cover layer (13) of the spacer fabric (11), wherein the blind holes (16) substantially pass through the lower cover layer (13) and the layer (15) having the spacer threads (14) and the upper cover layer (12) is substantially not weakened.

The present disclosure is directed to lamina(e) comprising cube corner elements, a tool comprising an assembly of laminae and replicas thereof. The disclosure further relates to retroreflective sheeting.

A three-dimensional structural molded part is provided having one or more pre-formed organometallic sheet-metal parts each having at least one edge. The organometallic sheet-metal parts are connected at respective edges at least partly by an injection-molded plastics material.

Methods for creating semolina flour-based shape-changing food from a multi-layered dough with at least one grooved surface. The dough layers have difference compositions including natural, staple and edible ingredients. The dough is exposed to stimuli during dehydration (e.g., baking) or hydration (e.g., boiling) processes.

A flexible packaging laminate has built-in opening/reclose and tamper-evidence features by forming the laminate from an outer structure joined in face-to-face relation to an inner structure. Score lines are formed in both structures to enable an opening to be formed through the laminate by lifting a flap or the like out of the plane of the laminate. The score line through the outer structure defines a larger opening than the score line through the inner structure, such that a marginal region of the outer structure extends beyond the edge of the opening portion of the inner structure. A pressure-sensitive adhesive is used to re-adhere the marginal region to an underlying surface of the inner structure adjacent the opening through the laminate. The outer score line includes at least one tear portion that is torn through upon initial opening, thus indicating the package has been at least partially opened.
