- the basis weight of the B layer is preferably 15 to 50 g / m 2 .
- the toughness value is calculated by the following formula.
- Toughness value
- the toughness of the sheet is determined in consideration of the tensile strength and the elongation. The reason is that the deformation of the casing after filling the meat (mainly due to the large elongation of the sheet) cannot be evaluated only by the tensile strength. This is because it is not possible to evaluate only by elongation.
- the toughness value is preferably 150 or more and 400 or less. When the value of toughness is within the above range, it is possible to suitably prevent the sheet from being ruptured at the time of meat filling or clipping and the casing from being deformed after the meat filling.

- the heat roller is preferably operated at a surface temperature of 140 to 190 ° C., a linear pressure of 3 to 40 kgf / cm, and a processing speed of 10 to 30 m / min. Further, either side of the A layer and the B layer may be brought into contact with the heat roller.
- the sheet formed by this thermal processing may be wound around a winding roller.
- Additional processing may be performed in which a colorant, flavor, spice, or the like is attached to the sheet. This additional processing is performed after the sheet is formed and before the casing is formed.
- the A layer forms the inner surface of the casing, that is, when the A layer is brought into contact with meat, a pigment, flavor, or the like is attached to the surface of the A layer.
- printing processing such as transfer may be performed on the surface of the A layer.
- the B layer may form the inner surface of the casing.
- the sheet is subsequently formed into a tubular casing.
- both sides extending in the longitudinal direction of a sheet that is long in the paper making direction are sealed with a heat sealer to form a continuous tubular casing.
- a method of performing sealing by superimposing inner surfaces of both sides of a sheet (Method I)

- the adhesive part formed by sealing may be continuous, or may be a discontinuous form such as a dot shape.
- the length in the width direction of the bonded portion is preferably selected in the range of 3 to 15 mm depending on the diameter of the casing to be formed.
- the heat sealer is preferably operated at a temperature of 150 to 230 ° C., a sealing pressure of 3.0 to 6.5 kgf / cm 2 , and a sealing time of 0.3 to 0.6 seconds.

Description
また、前記食肉包装用シートから形成された管状の食肉包装用ケーシングであって、A層が内側に配置された食肉包装用ケーシングが提供される。
本実施形態の食肉包装用シート(以下、単に「シート」という)は多層構造である。具体的には、シートは熱接着されたA層及びB層を有する。
すなわち、本発明において、シートの強靭性は引張強さ及び伸びを考慮して決定される。その理由は、食肉充填後のケーシングの変形(主としてシートの伸びが大きいことによる)は引張強さのみで評価することができず、また、食肉充填時やクリップ止め時のケーシングの破裂(主としてシートの引張強さが小さいことによる)は伸びのみで評価することができないためである。
A層とB層とを厚み方向に積層した後に加熱することによりシートを形成する。加熱は、例えば熱ローラを用いて行うことができる。A層及びB層を積層した状態で熱ローラに通すことにより、A層に含有されるポリエチレン及び低融点ポリエステル、ならびにB層に含有されるポリエチレンが溶融して各繊維同士が接着する。その結果、A層とB層とが接着され、一体化したシートが形成される。熱ローラは、表面温度140~190℃、線圧3~40kgf/cm、加工速度10~30m/分の範囲で運転されることが好ましい。また、A層及びB層のいずれの側を熱ローラと接触させてもよい。この熱加工により形成されたシートは、巻き取りローラに巻き取ってもよい。
製品の外観や風味を向上させるため、シートに着色料、フレーバー、香辛料等を付着させる付加加工を行ってもよい。この付加加工は、シートの形成後かつケーシングの形成前に行う。A層がケーシングの内面を形成する場合、すなわちA層を食肉と接触させる場合、A層の表面に色素やフレーバー等を付着させる。必要に応じてA層の表面に転写等の印刷加工を行ってもよい。ケーシングが無地である場合には、B層がケーシングの内面を形成してもよい。
シートは、続いて管状のケーシングに成形される。具体的には、抄紙方向に長尺なシートの長手方向に延びる両側部をヒートシーラーにより互いにシーリングし、連続した管状のケーシングを形成する。シーリングの具体例として、シートの両側部の内面同士を重ね合わせてシーリングを行う方法(方法I)と、シートの一方の側部の内面と他方の側部の外面とを重ね合わせてシーリングする方法(方法II)とがある。すなわち、方法Iでは、A層が内側にある場合にはA層同士をシーリングする。方法IIでは、A層とB層とをシーリングする。シーリングによって形成される接着部は連続していてもよいし、ドット状等の不連続な形態でもよい。接着部の幅方向の長さは、形成されるケーシングの直径等に応じて3~15mmの範囲で選択されることが好ましい。ヒートシーラーは、温度150~230℃、シール圧3.0~6.5kgf/cm2、シーリング時間0.3~0.6秒の範囲で運転されることが好ましい。
製造したケーシング内に食肉を充填し、ケーシングを封止する。一般的に、食肉の充填には食肉充填機を使用する。食肉充填機は、食肉を吐出する吐出ノズルが装着された充填管を備える。充填管にケーシングを被せた後、吐出ノズルから食肉を吐出し、ケーシングの内部に食肉を連続的に充填する。所定の充填圧に達するまでケーシングに食肉を充填した後、ケーシングの基端部を絞り、クリップで封止する。このとき、ケーシングの基端部の2箇所をクリップ止め(いわゆるダブルクリップ)することにより、食肉充填が完了したケーシングを密封し、同時に、次に食肉が充填されるケーシングの先端を封止することができる。
A層の繊維(a)、繊維(b)、及び繊維(c)として、ユニチカ製のメルティ(登録商標)6080(2.2dtx×5mm)、クラレ製のソフィット(登録商標)N720(2.2dtx×5mm)、及び帝人製のTA04PN(0.1dtx×3mm)をそれぞれ使用した。繊維(a):繊維(b):繊維(c)=30:65:5の質量比でこれらの繊維を混合し、円網抄紙機を用いて坪量21g/m2の湿式不織布を製造した。B層として、坪量20g/m2の不織布シート(ユニチカ製のエルベス(登録商標)T0203WDO)を用いた。

A層として、実施例1と同様の条件で坪量33g/m2の湿式不織布を製造した。B層として、坪量20g/m2の不織布シート(エルベス(登録商標)T0203WDO)を用いた。次に、A層とB層とを積層し、実施例1と同じ条件で熱ローラにより加熱した。これにより、坪量53g/m2のシートが形成された。
A層として、実施例1と同様の条件で坪量30g/m2の湿式不織布を製造した。B層として、坪量30g/m2の不織布シート(エルベス(登録商標)T0303WDO)を用いた。次に、A層とB層とを積層し、実施例1と同じ条件で熱ローラにより加熱した。これにより、坪量60g/m2のシートが形成された。
A層として、実施例1と同様の条件で坪量31g/m2の湿式不織布を製造した。B層として、坪量15g/m2の不織布シート(エルベス(登録商標)T0153WDO)を用いた。次に、A層とB層とを積層し、実施例1と同じ条件で熱ローラにより加熱した。これにより、坪量46g/m2のシートが形成された。
A層の繊維(a)、繊維(b)、及び繊維(c)として、ユニチカ製のメルティ(登録商標)6080(2.2dtx×5mm)、クラレ製のソフィット(登録商標)N720(2.2dtx×5mm)、及び帝人製のTA04PN(0.1dtx×3mm)をそれぞれ使用した。繊維(a):繊維(b):繊維(c)=45:50:5の質量比でこれらの繊維を混合し、円網抄紙機を用いて坪量19g/m2の湿式不織布を製造した。B層として、坪量30g/m2の不織布シート(ユニチカ製のエルベス(登録商標)T0303WDO)を用いた。
A層として、実施例1と同様の条件で坪量30g/m2の湿式不織布を製造した。このA層を単層のシートとして使用した。
坪量50g/m2の不織布シート(ユニチカ製のエルベス(登録商標)T0503WDO)を、B層のみからなる単層のシートとして使用した。
特許文献1に記載の実施例1と同等のシートを製造した。すなわち、針葉樹パルプSR20゜、クラレ製のソフィット(登録商標)N720(2.2dtx×10mm)、及びクラレ製のソフィット(登録商標)N721(1.7dtx×5mm)を10:25:65の質量比で混合し、円網抄紙機を用いて坪量56g/m2の湿式不織布を製造した。この湿式不織布を単層のシートとして使用した。
シートに対するヒートシールの強度試験を以下のように行った。
ヒートシールした2枚のシート片の同じ側の端部(例えば、一方のシート片の右側端部と他方のシート片の右側端部)をそれぞれチャックし、チャックした端部を徐々に離間させ、試験片が破断する時の荷重(N/15mm)を測定した。
ヒートシールした2枚のシート片の対向する側の端部(例えば、一方のシート片の右側端部と他方のシート片の左側端部)をそれぞれチャックし、チャックした端部を徐々に離間させ、試験片が破断する時の荷重(N/15mm)を測定した。
各実施例及び比較例のシートに135mm幅で抄紙方向の切込みを形成し、抄紙方向に長尺なシート片を得た。各実施例のシート片については、A層が内側になるように管状に巻き、上記方法IIにしたがって、一方の側部のA層と他方の側部のB層とを15mm重ね合わせた。西部機械製のHSP-400-SA型センタープレスシール製袋機に付属のヒートシールバーを使用し、10mm幅、温度180℃、シール圧6.0kgf/cm2、シーリング時間0.55秒の条件下、シーリングによって形成される接着部がドット状となるようにヒートシールした。このヒートシールにより、平面状態で60mm幅のケーシングを形成した。一方、比較例については、シートの外面及び内面を区別しなかったこと以外は上記実施例と同様にケーシングを形成した。
ケーシングを食肉充填機に装着した後、ケーシングへ食肉を充填した。チョッパーに掛けた豚肉及び豚脂にピックル液及び澱粉を混合して練り肉を形成し、これを食肉として使用した。吐出ノズルからケーシング内に20kg/分の速度で練り肉を吐出し、5.0kgf/cm2の充填圧で全長1mになるまで充填した。充填中のケーシングの破裂の有無を“A”又は“C”で評価した。“A”は充填中にケーシングが破裂しなかったことを表し、“C”は充填中にケーシングが破裂したことを表す。
ケーシングへの食肉充填後、ダブルクリッパー(Poly Clip社製FCA3430)を用いてケーシングの端部を絞り、クリップ(Poly Clip社製15-8 5×1.75)で封止した。クリップ止め時のケーシング内の圧力は6kgf/cm2であった。
両端をクリップ止めした食肉充填ケーシングを垂直方向に吊り下げ、75℃、湿度99%の条件下で60分間加熱し、続けて65℃、湿度15%の条件下で40分間乾燥させた。この乾燥工程の後、食肉充填ケーシングを吊り下げた状態のまま16℃、湿度85%の条件下で3週間熟成させ、サラミを完成させた。
完成したサラミからのケーシングの剥離容易性及び剥離したケーシングへの食肉の付着の程度を“A”、“B”又は“C”で評価した。“A”は食肉からケーシングが容易に剥離し、かつ剥離したケーシングに食肉が付着しなかったことを表し、“B”は食肉からケーシングが容易に剥離するが、剥離したケーシングに食肉が付着したことを表し、“C”は食肉からケーシングが剥離しにくかったことを表す。
