Abstract: A single use processing substrate including a first cut-resistant layer having a first surface area and including an absorbent ply and a thermoplastic material ply, wherein the first layer includes a plurality of non-circular apertures therein and a second layer having a second surface area and including an absorbent ply and a thermoplastic material ply, wherein the first layer is secured to the second layer such that a portion of the second surface area is laterally disposed outside of the first surface area.

Abstract: A processing substrate includes a first cut-resistant layer having a first surface area and including an absorbent ply and a thermoplastic material ply and a second layer having a second surface area and including an absorbent ply and a thermoplastic material ply. The thermoplastic material ply of the second layer is tinted a certain color for indicating absorption of the absorbent ply of the second layer.

Abstract: A method of manufacturing a single use processing substrate includes the step of extruding a first layer having ridges and troughs between the ridges. The method further includes the steps of placing a second layer into the troughs while the first layer is pliant and compressing the pliant ridges so that the second layer is bound into the troughs.

Abstract: A single use processing substrate comprises a first cut-resistant layer having a first surface area with a width and including a first absorbent ply and a first thermoplastic material ply. The substrate also includes a second layer having a second surface area and including a second absorbent ply and a second thermoplastic material ply. A plurality of adhesive portions secures the first layer to the second layer, wherein each adhesive portion has an effective dimension shorter than the width of the first layer and wherein the first layer is secured to the second layer such that a portion of the second surface area is laterally disposed outside of the first surface area.

Abstract: A processing substrate includes an absorbent material layer and randomly spaced strands of thermoplastic material disposed on a side of the absorbent material layer forming a cut resistant and liquid pervious surface. The method of producing the processing substrate includes providing an absorbent material layer, moving the absorbent material layer, and depositing randomly spaced strands of material onto a side of the absorbent material layer to form a cut resistant and liquid pervious surface.

Abstract: A recloseable multibag freezer bag including an inner liner bag and an outer support bag. The inner liner bag is a thermoplastic with a thickness of less than 2 mil and a specified secant modulus, has a mouth through which the interior of the inner liner bag is accessible, and is joined by a mouth seal to the throat of the support bag along the entire length of the mouth of the liner bag substantially enclosing an air space between facing walls of the inner liner bag and outer support bag. The outer support bag is a thermoplastic, and has a mouth and a throat. A recloseable mouth seal is affixed to its mouth to provide recloseable access to the interior of the liner bag through the outer bag while maintaining the enclosed air space between the inner and outer bags.

Abstract: A processing substrate comprises a first material having a liquid-permeable surface, a second material disposed adjacent to the first material and having a liquid-absorbent portion and a third material disposed adjacent the second material and having a liquid-impermeable surface.

Abstract: The present invention provides a freezer bag comprising a multibag having at least an inner liner bag and an outer support bag, the inner liner bag having a first sidewall and a second sidewall attached together along respective lateral edges forming edge seals, each sidewall having a top edge, and the liner bag having a folded edge defining the bottom of the liner bag, the outer support bag having two sidewalls attached together along respective lateral edges forming edge seals, each sidewall having top edges defining the opening to the multibag, and the support bag having a folded edge defining the bottom of the multibag, the top edges of the liner bag being attached to an inner surface of each respective sidewall of the support bag wherein the liner is thermoplastic and has a thickness of less than 2.0 mil (50.8 micron).
