The present invention relates to a flat, multilayered, low moisture, barrier, laminated thermoplastic film with an absorptive food contact layer coated with a flavoring and/or coloring agent, which can be formed on automatic stuffing machinery into a sealed tube in a continuous manner for use as a food casing. This film has an absorptive food contact layer, an oxygen barrier layer, and a polyethylene outer layer. The coloring and/or flavoring agent on the absorptive layer is released onto the surface of encased foodstuff during cooking and processing.

A description is given of a tubular food casing having a fiber layer on the inside and having two or more polymer layers. The polymer layers include a first continuous polymer layer (A), with which the inner fiber layer or nonwoven-web layer is coated on the side of the tubular casing facing away from the inside, and completely covers the layer, and at least one polymer layer (B), and a monoaxially or biaxially oriented film based on polyamide and/or copolyamide. At least two of the polymer layers are joined to one another directly by a layer of adhesive. The inner fiber layer may absorb colour, smoke, aroma and/or flavour substance(s), such as liquid smoke or caramel, store these substances and transfer them to a food located within the casino. The casing is suitable as artificial sausage casing, especially for cooked-filling and scalded-emulsion sausage.

Provided is a multilayered coextruded thermoplastic food casing comprising a porous inner layer capable of absorbing, retaining, desorbing and transferring at least one functional additive to food encased in said casing; a layer having a barrier effect for water vapor; and an adhesive layer, wherein the porosity of said porous inner layer is generated by (co)extruding a composition comprising a polymer and a supercritical pore-forming agent, and a method for producing said multilayered coextruded thermoplastic food casing.

Manufacturing a multilayer tubular fibrous reinforced food casing having a tubular fibrous web located between an inside viscose regenerated cellulose layer and an outside viscose regenerated cellulose layer includes injecting a peeling agent in an outside viscose stream, injecting an adhesion promoter in an inside viscose stream, and impregnating the tubular fibrous web with viscose by applying the inside viscose stream to an inside surface of the fibrous web and applying the outside viscose stream to an outside surface of the fibrous web.

Rigid shirred food casing articles (e.g., shirred sticks of casing material) include a cohesion-enhancing solution applied to at least one surface of the casing material. The cohesion-enhancing solution comprises at least one polysaccharide (e.g., dextrin) and a predominantly non-aqueous solvent (e.g., comprising propylene glycol). The coherency-enhancing solution comprises less than 50 wt. % water. Related methods and compositions are also disclosed.

Provided are a paper material for fibrous casing enabling a fibrous casing to deliver favorable performance, a production method thereof, and a fibrous casing employing the paper material for fibrous casing. The paper material for fibrous casing of the present invention is used as a food packaging material in heat processing of a foodstuff, and is formed from pulp as a principal component, with one face being a glossy face and another face being a matte face. The fibrous casing of the present invention comprises: a paper layer that is arranged as an innermost layer and formed from a paper material; and a synthetic resin layer that is overlaid on an outer face of the paper layer, the paper material being the paper material for fibrous casing. The matte face of the paper material is preferably directed inward. The glossy face of the paper material is also preferably directed inward.
