Abstract: An elongate strip (10) is disclosed which can be manipulated into a cylindrical shape to form a casing for a food product. The strip comprises films of synthetic plastics material which are laminated together. One of the two outer films of the laminate is a peelable ionomer and the other is an olefin. A plurality of web weakening formations (18) for facilitating initiation of transverse tearing of the web are provided along one of the longitudinal edges of the web. The formations constitute the boundaries of a plurality of pull tabs (20). The weakening formations can be lines of perforations extending inwardly from said one edge of the web

Abstract: A method of preparing smoke-impregnated tubular casings is described. The process comprises: (a) providing a tubular casing having interior and exterior surfaces, the tubular casing being selected from cellulose fiber tubular casings and synthetic tubular casings, and the tubular casing being suitable for encasing food fillings having a form selected from one of liquid and paste; (b) applying to the interior surface of the tubular casing a mixture comprising, (i) liquid smoke, (ii) browning agents, and (iii) optionally water; (c) allowing the mixture to remain in contact with the interior surface of the tubular casing for at least 5 days; and (d) optionally shirring and watering the mixture treated casing. The smoke-impregnated tubular casings prepared in accordance with the method of the present invention are suitable for liquid or paste-like food fillings, such as sausagemeat emulsions.

Abstract: A heat-shrinkable backseamed casing film comprises a first layer, a second layer, and a third layer, with the first and third layers being outer layers and the second layer being between the first layer and the third layer. The first outer layer serves as an inside casing layer, and comprises polyolefin; the second layer comprises polyester and/or polyamide; the third layer serves as an outside casing layer and comprises polyolefin, polystyrene, and/or polyamide. The second layer has a thickness of at least about 5% of a total thickness of the heat-shrinkable casing film. Alternatively, the first layer comprises polyolefin and has a surface energy level of less than about 34 dynes/cm; the second layer comprises a polyamide having a melting point of at least 300null F.; and the third layer comprises polyolefin, polystyrene and/or polyamide. A package comprises a cooked meat product within the backseamed casing. The second layer of the casing film prevents or reduces necking down on the forming shoe during backseaming. The backseamed casing is especially useful for cook-in applications.
