Abstract:
The invention relates to a food casing from a two-dimensional fiber structure, which is coated on one or both sides with acrylic resin. The acrylic resin is combined with at least one other natural and/or synthetic polymer. The acrylic resin in the coating may be admixed with the other polymer. The latter can also form a layer of it's own. On the inside of the casing (i.e. on the side facing the food), this coating prevents gelling out, while at the outside it has a mainly permeability-increasing effect. The casing is particularly used as artificial sausage casing, especially for cooked-smoked sausages.
Abstract:
A tubular encasing netting for sausage and similar articles. The encasing netting contains a longitudinally running tear-open thread, the length of which is greater than that of the encasing netting in the state of use of the latter. This results in loops of the tear-open thread which are accessible from outside and which can be grasped for tearing open. The encasing netting is expediently a double-rib or warp-knit fabric. The tear-open thread is received in stitches of this fabric. The invention relates, furthermore, to a method for producing such an encasing netting, to a sausage casing connected to the encasing netting and to an article encased by this encasing netting.
Abstract:
A food casing is described with or without flat reinforcement insert and a smoke-permeable costing, preferably of protein, cellulose or acrylic. The insert is preferably a consolidated nonwoven or spunbonded nonwoven, a woven fabric, loop-formingly knitted fabric, laid fabric or loop-drawingly knitted fabric. The flat strip is glued to form a tube using a smoke-permeable gluing medium, preferably blood, plasma, protein, or other proteins. The food casing is preferably used as artificial sausage casing or cheese casing.
Abstract:
A food casing includes an outer barrier layer, and an inner absorbent layer formed as a separate body from the outer barrier layer wherein the outer barrier layer and the inner absorbent layer are in frictional contact. Another food casing includes an outer barrier layer, and an inner absorbent layer formed as a separate body from the outer barrier layer wherein the outer barrier layer and the inner absorbent layer are not physically connected. A method for forming a food casing includes wrapping an outer barrier layer around an inner absorbent layer and sealing the outer barrier layer along a seam. The inner absorbent layer and the outer barrier layer of the resulting food casing are in frictional contact.
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.
Abstract:
A backseamed casing has a casing film comprising a first outer layer and a second outer layer, the first outer layer containing a polyamide having a melting point of from about 250-400.degree. F., and the second outer layer containing a polyamide having a melting point of from about 250-400.degree. F. A butt-sealed backseamed casing has a casing film to which a butt-seal tape film is sealed, the casing film having an inside layer containing a polyamide having a melting point of from about 250-480.degree. F., and an outside layer comprising polyolefin, with the butt-seal tape film comprising polyolefin. A heat-shrinkable film has a first outer layer, a second outer layer, and an inner layer. The first outer layer contains a first polyamide having a melting point of from about 250-400.degree. F.; and the second outer layer contains a second polyamide having a melting point of from about 250-480.degree. F.; the inner layer contains a first composition comprising at least one member selected from the group consisting of a third polyamide, a polyester; and, the first inner layer having a thickness of at least about 5% of a total thickness of the heat-shrinkable film. A package comprises a cooked meat product packaged in the film or casing according to the invention, in which the cooked meat adheres to the film.
Abstract:
An improved method is disclosed for the fusing, joining or seaming of cellulosic materials. The method utilizes a hydroxide solution of selected organometallic compounds or metal oxides to rapidly crosslink opposing, overlapping cellulosic surfaces to provide secure seams. In particular, the invention is directed to the production, either on-line or off-line, of tubular cellulosic casings for the manufacture of sausages and sausage-like products. The seams according to this invention have such high shear strength that extremely narrow bond widths are possible. The narrowness of the bond site eliminates or minimizes striping or discoloration of the finished product.
Abstract:
A web-shaped or tubular packaging film for use in food packaging applications, particularly as a sausage casing, is comprised of a carrier layer based on fiber-reinforced celulose and a closed thermoplastic, sealable resin coating based on copolymers containing vinylidene chloride (VDC) units. To improve the kink resistance, this resin coating is built up from at least two superposed layers, the first resin coating layer adjacent to the carrier layer being composed of a VDC copolymer forming flexible films and the outer, second resin coating layer being composed of a VDC copolymer forming rigid films. The web-shaped film is suitable for the production of tubular packaging casings, in particular sausage casings, with a longitudinal seam.
Abstract:
Disclosed is a shirred sausage casing of a web film in the form of a tubing which comprises a seam region, formed from the edge regions of the web film, which extends in a helically twisted manner about the longitudinal axis of the casing in a manner wherein more than 10 helical turns are present in a 10 m length of the casing. Also disclosed is a process for producing a casing of this type.
Abstract:
Disclosed is a tubular casing of fiber-reinforced regenerated cellulose comprising a film web which is curved to form a tube. The edge regions of the film web, which run parallel to the longitudinal axis, abut or overlap slightly and are sealed by means of a film strip which covers both the edge regions. The film web and the film strip composed of the same material have, in the wet remoistened stage, a breaking strength of about 15 to 30 N/mm.sup.2 and an elongation at break of about 30 to 50% in the longitudinal direction of the web, and a breaking strength of about 15 to 35 N/mm.sup.2 and an elongation at break of about 30 to 50% in the transverse direction of the web. The breaking strength in the transverse direction of the web is equal to or greater than that in the longitudinal direction of the web. On its entire surface facing the film strip, the tubular casing has a substantially gas-impermeable and sealable layer, as has the film strip on the surface which comes into contact with the tubular casing. The film web is produced from viscose, and is prevented from shrinking during the process and is stretched in the transverse direction during drying. The tubular casing finds particular application as a sausage casing.
