Abstract: An anti-static film comprises one or more polymeric film layers having a layer of conductive, low capacitance material secured thereto. The polymeric film layer(s)may have pinholes formed therethrough. The conductive, low capacitance layer comprises one or more strands of conductive, low capacitance fiber arranged in a predetermined pattern. The polymeric film layer(s) are bonded to the conductive, low capacitance material using a polymeric layer formed from the same material as the film layers. Alternatively, the layer of conductive, low capacitance material may be omitted, with the adhesive layer being extruded onto the polymeric layer having pinholes formed therethrough. Similarly, an anti-static fabric comprises one or more layers of woven polymeric material having a layer of conductive, low capacitance material secured thereto. Alternatively, the fabric may have a polymeric layer extruded thereon in which pinholes are formed.
Abstract: A method of manufacturing a shoe lining having anti-microbial properties. The method comprises providing a quantity of a thermoplastic resin including an inorganic zinc-based anti-microbial agent admixture having a predetermined microbial inhibition characteristic. This thermoplastic resin is blended with a polyethylene resin to form an anti-microbial feedstock. The anti-microbial feedstock is formed into relatively long, narrow, thin lengths of anti-microbial members. These members are woven into an anti-microbial fabric having predetermined microbial inhibition characteristics. This fabric is cut into a plurality of pieces in accordance with a predetermined pattern and the pieces are joined together thereby constructing the anti-microbial shoe lining.

Abstract: A process of manufacturing a bulk bag begins with a length of tubular woven polypropylene material which is cut along first transversely extending lines 64 to form the upper edges of lift sleeve portions 76, cut along longitudinally extending lines 66 to form the side edges of the lift sleeve portions 76, and cut along substantially transversely extending lines 68 situated at the midpoint of the lines 66 to form opposed top wall halves 72 and opposed bottom wall halves 74. The top wall halves and the bottom wall halves are then sewn together along sew lines 82 and 84, respectively. Sidewalls 70' are joined to the bottom wall halves 74 along sew lines 86, and the top wall halves 72 are joined to the sidewalls 70' along sew lines 88. The lift sleeve portions 76 may be configured to provide lift sleeve, lift rope, or single point lift construction. The top and bottom walls may be provided with a fill chute and discharge chute, respectively.
Abstract: A process for the construction of a bulk container including a glued bottom portion. A blank is suspended in the shape of the desired container and is positioned over a bottom portion. Adhesive or glue is applied to the bottom portion in areas which will contact the blank. The blank is lowered into contact with the blank and fins are formed. The fins are either folded, cut and/or secured to complete the container in one of several ways.
