A description is given of a tubular food casing having a glued, permanently elastic longitudinal seam based on a flat fibrous material coated with acrylic, collagen and / or a protein derived therefrom. The seam is generated using a reactive hotmelt glue. The glued seam is resistant to boiling for a long time and also exhibits sufficient stability thereafter. The insert is preferably a textile material, a concolidated nonwoven or spunbonded nonwoven, a woven fabric, loop-forming knitted fabric, laid fabric, loop-drawingly knitted fabric or a fiber paper. It is coated in the flat state. The coated longitudinal strip is cut into strips according to the diameter of the casing to be produced and glued using a PUR hotmelt glue to form the tube. The food casing is preferably used as artificial sausage casing or for wrapping cheese or fish.

The present invention provides a functional additive transferring (co)extruded thermoplastic food casing having a water vapor barrier and / or oxygen barrier effect wherein an inside surface of the thermoplastic food casing has a textured surface which forms a three-dimensional pattern of higher and lower retaining capacity for a functional additive, wherein the thermoplastic food casing having a textured surface in case of a monolayer casing or an inner layer comprising the inside surface having a textured surface in case of a multilayer casing comprises as a main component at least one thermoplastic polymer material selected from the group consisting of (co)polyamides, (co)polyolefins, (co)polyester and vinylidenchloride (co)polymers, wherein the (co)extruded thermoplastic food casing does not comprise a net and / or a material forming a net or any other three dimensional structure on its outside surface, wherein the average thickness of the thermoplastic food casing in the areas having a higher retaining capacity is in a range of from 1 to 100 μm, wherein the average thickness of the thermoplastic food casing in the areas having a lower retaining capacity is in a range of from 191 to 2000 μm, provided that the thickness difference between the average thickness in the areas having higher retaining capacity and the average thickness in the areas having a lower retaining capacity is in a range of from 160 to 1950 μm and that a ratio of the average thickness of the thermoplastic food casing in the areas having a higher retaining capacity and the average thickness of the thermoplastic food casing in the areas having a lower retaining capacity is in a range of from 0.002 to 0.25.

The invention discloses a preparation method of cellulose viscose and application of the cellulose viscose in cellulose casings, and belongs to the technical field of viscose, the preparation method of the cellulose viscose comprises the steps of viscose solution preparation, viscose solution modification, spinning and post-treatment; the application of the cellulose mucilage glue in the cellulose casing comprises the steps of weaving forming, sizing, primary drying, washing sizing and secondary drying. While the toughness, antistatic property and spinnability of the cellulose casing are improved, the water vapor permeability, wet modulus, dimensional stability, elasticity, wear resistance and acid and alkali resistance of the cellulose casing are improved.

The invention discloses a production process of a color-transferable biological cellulose casing. The production process comprises the following steps: viscose preparation, filtering and defoaming treatment, forming and regeneration reaction, washing and desulfurization treatment, dyeing and plasticizing treatment, pre-drying and drying treatment, humidifying treatment, coiling treatment, shrinkage treatment, packaging and piece forming. The natural cellulose wood pulp (cotton pulp) is adopted as the raw material, the product can be naturally degraded, is green and pollution-free, is a green and environment-friendly food packaging material, has excellent water permeability and air permeability, can achieve a better smoking effect, is good in moisture retention performance, is better in flavor of the fumigated sausages, and in the steaming process of the sausages, the color of the surface of the casing can be transferred from the surface of the casing to the meat surface of the sausage, bright meat color required by customers is formed on the surface of the sausage, and unique fragrance is formed.

The invention relates to a preparation method of a fresh collagen casing, and belongs to the technical field of casing preparation. The preparation method of the fresh collagen sausage casing comprises the following steps: (1) preparing the castrated bull skin with the age of 1-2 years, wherein the skin material isfull grain cow leather of 6-8 mm in thickness; (2) pickling the skin material for 40-90 days at the temperature of 10-20 DEG C; (3) carrying out ash washing, acidification and defibration on the pickled leather to obtain collagenous fibers; and (4) adding nano cellulose into the collagen fiber to obtain a collagen group, filtering and carding the material, and blowing the material to obtain the fresh collagen casing. The method is scientific, reasonable and simple and convenientto operate, and the prepared sausage casing is high in elongation at break, small in thickness, increased in breaking resistance value, high in light transmittance and good in effect when used for frying and baking.

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.
