Description of the Related Art Conventionally, when manufacturing a kneaded product such as ham and sausage, a packing material for meat such as fiber lath casing and cellulose casing, which is excellent in air permeability and smokeability, has been used. However, since this casing is obtained by processing linen paper or non-woven fabric into a tubular shape and then impregnating or applying viscose, the steps such as viscose processing are complicated, and acid treatment, alkali treatment, and water washing are also required. Since processing is required, productivity is low, and toxic gas may be generated when the casing is incinerated,
There was a problem with the environment and safety. Further, in the above casing, when the casing surface in contact with the kneaded product is subjected to a seasoning process such as sauce taste, spice taste, and aromatization, it is difficult to carry out in a sheet state, and it is necessary to make it into a tubular shape, and productivity is improved. However, there is a drawback that it is further reduced. Further, JP-A-6-153772 proposes to use a meltblown non-woven fabric using a fiber having a bulk density of 0.15 g / cm 3 or more and a fiber diameter of 10 μm or less as a meat casing. However, when this casing is filled with the kneaded product, the kneaded product enters the fiber gaps of the densified non-woven fabric, so that when the casing is removed after the smoking process or the like, there is a problem that the meat separation becomes poor and the fibers adhere to the meat. there were.

後に充填物の肉離れが低下する。In the present invention, the thickness of the joining sheet is determined from the viewpoints of air permeability, strength, meat processing property, product handling property, etc.
The thickness is 0.05 to 1 mm, preferably 0.1 to 0.6 mm, more preferably 0.15 to 0.4 mm. The thickness is 0.
If it is less than 05 mm, the air permeability will be high, but the joint sheet will stretch during the filling of the kneaded product and easily break, making handling difficult. On the other hand, if it exceeds 1 mm, the strength will increase,
It becomes hard and highly rigid, and the workability in the case of forming a tubular shape and the filling workability of the kneaded product are deteriorated, the shape of the filling is deteriorated, and the air permeability is further deteriorated. Further, the air permeability of the bonding sheet by the Gurley method is 0.1 to 100 seconds / 100 cc, preferably 0.3 to 50 seconds / 100 c from the viewpoint of efficiency of smoking processing, meat processing, etc. after filling the kneaded product.
c, more preferably 0.5 to 30 seconds / 100 cc. If the air permeability exceeds 100 seconds / 100 cc, the smokeability and meat processability are insufficient due to the low air permeability.
On the other hand, if it is less than 0.1 sec / 100 cc, the air permeability will be high, and the smokeability will be improved, but since the sheet has large voids, the kneaded product will enter the sheet gap, and the kneaded product will come out from the sheet gap during filling. It also facilitates and reduces filleting of the fill after processing.

合がある。The burst strength of the joining sheet is determined from the viewpoint of preventing the joining sheet from stretching, swelling, and breaking during the filling and processing of the kneaded product, both when it is dry and when it is wet (when it is wet by immersing it in water). The pressure is 0.1 MPa or more, preferably 0.2 to 5 MPa, more preferably 0.3 to 3 MPa. Further, in the present invention, the tensile strength of the bonded sheet is 80 N / 5 cm or more in the longitudinal direction and 25 N / 5 in the lateral direction from the viewpoint of maintaining strength and preventing breakage when filling the kneaded product.
cm or more, more preferably 100 to 600 N / 5 cm in the longitudinal direction and 30 to 300 N / cm in the lateral direction.
It is 5 cm. The vertical direction means the length direction (machine flow direction) in the case of a tubular shape, and the horizontal direction the thickness direction (direction perpendicular to the machine flow direction) in the case of a tubular shape. Say. The ratio of the tensile strength in the longitudinal direction to the tensile strength in the lateral direction (longitudinal / lateral) is preferably in the range of 2 to 6, more preferably 3 to 5. If the ratio of the tensile strength in the longitudinal direction to that in the lateral direction is less than 2,
Since the number of fibers arranged in the lateral direction is large, the joining sheet is less likely to be broken when the filler after processing is taken out, and it becomes necessary to use a cutter or the like, which lowers workability. If the ratio of length to width exceeds 6, the strength of the sheet in the horizontal direction may not be maintained.
