A heat-sealing apparatus for forming a composite heat seal structure, includes a belt conveying, heating and press bonding portion configured to convey and heat a heat seal material to form a band-shaped peelable seal, and a die roll press bonding portion configured to add a linear peelable seal to the band-shaped peelable seal in a longitudinal direction of the band-shaped peelable seal for forming the composite heat seal structure.

The present invention relates generally to a new and improved paper-based container. More specifically, the invention relates to a paper-based container that is comprised of a relatively low-density polyethylene coating on one or both surfaces of the container and at least two skive flaps, wherein each of said skive flaps is created during the manufacturing process. The skive flap further comprises at least one leading edge of the container body, and prevents unwanted moisture from entering the container and the contents of the container from saturating the paper-based material. One skive flap is preferably folded in a manner in which a portion of the outside surface of the container is adhered to the inside surface, and a second skive flap is adhered to the outside surface.

Methods produce a folded connection, sealed by means of an adhesive composition and by means of first and second sheetlike elements, wherein a flange of the first sheetlike element, having a first surface (11) and a second surface (12), is taken back over a flange of the second sheetlike element. The methods apply at least one layer of an adhesive composition to the flange of the first sheetlike element, bead the flange of the first sheetlike element around the flange of the second sheetlike element, and apply the adhesive composition to both the first and second surfaces of the flange of the first sheetlike element.

An apparatus is configured to make containers from sheet material. The apparatus includes a supply station for supplying a film having at least one folded portion having three or more film flaps folded and superimposed with respect to each other; a welding station configured to receive the film. The welding station comprises a welding head configured for welding the folded portion of the film and forming a container defining a housing compartment; the welding head comprises a heater made of electrically conductive material whose electrical resistivity, at least in a predetermined temperature range, decreases upon the increase of the temperature of the same electrically conductive material.

A fire retardant cushioning device wherein the cushioning device comprises a main body formed of a fire retardant cover material which is assembled together from panels of fire retardant cover material with the panels being connected together by at least one welded seam extending about the edges of the panels of cover material to form a seamed fire retardant cover material comprising the main body of the cover and the seam(s); and wherein the construction of the cushioning device provides a fire retardant cushioning device having welded seam(s) whereby the welded seam(s) are configured such that they are flame retardant. A fire retardant, infection control cushioning device is also disclosed. The invention also provides a method of manufacturing the fire retardant cushioning device.

An apparatus including a first surface configured to attach the apparatus to a second surface of another object, and a plurality of elongated nanofibers. Each nanofiber has one end connected to the first surface and an opposite end extending away from the first surface. The plurality of elongated nanofibers is configured to adhere to the second surface by nanoadhesion when brought into contact with the second surface.

Various fabric products incorporating exterior hydrostatic barriers and processes for manufacturing such fabric products are provided.

A method for sealing a seam in a fabric provides for joining at least one piece of a stretchable, one-ply woven fabric to another fabric such as another stretchable one-ply woven fabric, and for sealing the seam with a strip of another piece of fabric with an adhesive laminated thereon. The stretchable one-ply woven fabric includes elastic and inelastic fibers. A seam is produced in which the fabric fibers adhere to the seam and do not pull back from the seam. Also provided is a method for forming a hem and sealing the hem with a strip of another piece of fabric, to produce a hem that is resistant to fiber slippage. The method is advantageously used to form denim and other garments from woven fabrics that include at least 65% natural fibers along with various elastomeric fibers.

A medical gown (701) includes a layer of material (100) with a seam (401) disposed across the layer of material. The material can include a weave (110) of untwisted, continuous filament polyester. The material can also include a carbon filament (109). The seam is sealed by applying a tape (200) across the seam and applying heat to cause the tape to attach to the weave.

A pinched sack, which is made at least partially from a plastic material in the form of a tube section, has at least one pinched bottom at one end of the tube section. At least some of the plastic material is stretched, and at least one pinched bottom is provided by a thermally induced bonding process.
