A process of constructing an air tight and water tight seam, comprising cutting a sheet of selected material into two or more panels, sealing the panels at respective selected edges using an ultrasonic machine to form a seam, overlaying the seam with a tape made of the same selected material, and sealing the tape and seam using a radio frequency (RF) welding machine.

Systems and methods of using ultrasonic welding to form labels with RFID tags are disclosed. The methods can be useful for the production of a large volume of labels such as production with roll-to-roll processing. The labels can be useful for consumer products such as garments. The present invention discloses in one embodiment, a label having a first and second printed fabric label layer such that a radio frequency identification (RFID) inlay is disposed between the two printed fabric layers.

Disclosed herein are improved overlapping waterproof seams and methods of producing the same.

A fluid impervious stitching method for a seam of a vapor-permeable virus-barrier laminate. The laminate comprises: at least one thermoplastic resin fiber layer; at least one vapor-permeable virus-barrier thermoplastic elastomer film layer; and a bonding layer located between the two layers and formed of an adhesive capable of being fused with the two layers. In the stitching method, overlapping or stacking is performed to form a seam, and heat sealing is performed on the laminate at the seam. The temperature of heat sealing is higher than the melting point of a material layer having the highest melting point in the laminate, but lower than the temperature at which perforation or decomposition occurs in any material layer in the laminate. The heat-stitched seam has excellent windproof, vapor-permeable, virus barrier and liquid-barrier performance, has a smooth appearance without wrinkles, and feels soft. Also provided is a protective textile product prepared by means of the stitching method.

The invention relates to a below grade, blind side, waterproofing sheet membrane with adhesive and quartzeral granular particle layer, and having a top release liner, and a bottom release liner, enhancing bond strength between sheets, and be able to fully bond to concrete/shotcrete, and a method of making, and using same. The inventive waterproofing sheet membrane with adhesive, has at least one layer of quartzeral granular particle layer that are fully or partly embedded into the adhesive layer, and where the average reflectivity of the exposed granular particles is between about 30 percent to 80 percent reflectivity on a standard reflectivity scale. The quartzeral sand or granular particles are hydrophobic, and any moisture or water can be easily removed from its surface. Even a wet quartzeral surface allows an adhesion or bonding of an adhesive to the quartzeral surface.

A welder for joining two polymeric sheets together using a wedged heating element allows for a heating profile on opposite faces of the heating element to be varied by controlling where each of the polymeric sheets contacts the corresponding face.
