Description
本発明は、成形性に優れたアルミニウム箔製包装材料に関し、特に、プレススルーパック包装の容器本体として使用するのに適したアルミニウム箔製包装材料に関するものである。 The present invention relates to an aluminum foil packaging material excellent in formability, and more particularly to an aluminum foil packaging material suitable for use as a container body for press-through pack packaging.
従来より、薬剤や食品等の錠剤又は電子材料等の包装体として、プレススルーパック包装が用いられている。プレススルーパック包装の容器本体としては合成樹脂製フィルムが用いられ、蓋材としてはアルミニウム箔が用いられている。容器本体には錠剤等を個別に収納するための複数のポケットが成形されている。合成樹脂製フィルムは可塑性が良好であり、成形性に優れているため、容器本体の材料として、合成樹脂製フィルムが汎用されている。 Conventionally, press-through pack packaging has been used as a package for tablets such as drugs and foods, or electronic materials. A synthetic resin film is used as the container body of the press-through pack packaging, and an aluminum foil is used as the lid. The container body is formed with a plurality of pockets for individually storing tablets and the like. Synthetic resin films have good plasticity and excellent moldability, and therefore synthetic resin films are widely used as materials for container bodies.
しかしながら、容器本体が合成樹脂製フィルムで構成されていると、湿気が錠剤に侵入しやすく、錠剤が劣化しやすいということがあった。また、合成樹脂製フィルムは透明なものが多く、紫外線の照射によって、錠剤が劣化しやすいということもあった。このため、容器本体の材料として、アルミニウム箔と合成樹脂製フィルムとの積層体を用いることも行われている。 However, when the container body is made of a synthetic resin film, moisture tends to enter the tablet, and the tablet is likely to deteriorate. In addition, many synthetic resin films are transparent, and tablets may be easily deteriorated by irradiation with ultraviolet rays. For this reason, using the laminated body of aluminum foil and a synthetic resin film as a material of a container main body is also performed.
かかる積層体を用いると、湿気が侵入しにくく且つ紫外線も照射されにくいため、錠剤の劣化を防止でき、好ましいものである。しかるに、かかる積層体は、合成樹脂製フィルム単独のものに比べて、成形性に劣るものであった。このため、アルミニウム箔に積層一体化される合成樹脂製フィルムとして、縦方向（ＭＤ方向）と横方向（ＣＤ方向）の熱水収縮率が一定の範囲にあるポリアミド系フィルムを用いることが提案されている（特許文献１）。 When such a laminate is used, it is difficult for moisture to enter and ultraviolet light is not easily irradiated, so that deterioration of the tablet can be prevented, which is preferable. However, such a laminate was inferior in moldability as compared with a synthetic resin film alone. For this reason, it is proposed to use a polyamide-based film in which the hot water shrinkage in the vertical direction (MD direction) and the horizontal direction (CD direction) is in a certain range as a synthetic resin film laminated and integrated on the aluminum foil (Patent Document 1).
しかしながら、特許文献１記載の技術は、アルミニウム箔に積層一体化される合成樹脂製フィルムを特定しただけであるので、積層体としての成形性が良好であるとは言えなかった。また、ポリアミド系フィルムの熱水収縮率と、成形性には相関関係がないので、積層体としての成形性が良好であるとは言えなかった。すなわち、積層体としての常温下での伸びや応力は全く考慮されていないため、常温での成形時において、容器本体を構成する積層体に割れが生じたり、成形後のポケットが変形しやすいということがあった。 However, since the technique described in Patent Document 1 only specifies a synthetic resin film laminated and integrated on an aluminum foil, it cannot be said that the moldability as a laminate is good. Moreover, since there is no correlation between the hot water shrinkage of the polyamide film and the moldability, it cannot be said that the moldability as a laminate is good. That is, since the elongation and stress at room temperature as a laminate are not considered at all, at the time of molding at room temperature, the laminate constituting the container body is cracked or the pocket after molding is likely to be deformed. There was a thing.
本発明は、容器本体を構成する積層体として特定のものを採用することにより、成形時に割れが生じたり、成形後に変形が生じたりするのを、防止することを課題とするものである。 This invention makes it a subject to prevent that a crack arises at the time of shaping | molding or a deformation | transformation arises after shaping | molding by employ | adopting a specific thing as a laminated body which comprises a container main body.
すなわち、本発明は、ポリアミド系フィルム，第一接着剤，アルミニウム箔，第二接着剤及びポリ塩化ビニル系フィルムの順に積層された積層体で構成されたアルミニウム箔製包装材料において、前記積層体は、縦方向、横方向、４５°方向及び１３５°方向のいずれの方向においても、その伸び（Ｌ）が１００〜１４０％の範囲内であり、かつ、ΔＥが０．５０〜０．６５の範囲内であることを特徴とするアルミニウム箔製包装材料に関するものである。ここで、ΔＥとは以下で定義される値である。すなわち、ΔＥ＝（Ｓ−Ｐ）／（Ｌ−０．２）なる式で算出される値であり、Ｓは破断時の応力（Ｎ／ｍｍ2）、Ｐは０．２％耐力（Ｎ／ｍｍ2）、Ｌは伸び（％）を表している。 That is, the present invention is an aluminum foil packaging material composed of a laminate in which a polyamide film, a first adhesive, an aluminum foil, a second adhesive, and a polyvinyl chloride film are laminated in this order. In any of the vertical direction, the horizontal direction, the 45 ° direction, and the 135 ° direction, the elongation (L) is in the range of 100 to 140%, and ΔE is in the range of 0.50 to 0.65. It is related with the packaging material made from aluminum foil characterized by being inside. Here, ΔE is a value defined below. In other words, ΔE = (SP) / (L−0.2) is a value calculated by the equation: S is stress at break (N / mm 2 ), P is 0.2% proof stress (N / mm 2 ) and L represent elongation (%).
本発明に用いるポリアミド系フィルムとしては、一般的にナイロンフィルムが用いられ、特にナイロン６フィルム又はナイロン６６フィルムが用いられる。ポリアミド系フィルムの厚さは２０〜３０μｍ程度であり、特に２５μｍのものが用いられる。ポリアミド系フィルムは、チューブラー法又はテンター法で製造され、一般的には二軸延伸して製造される。二軸延伸は、同時二軸延伸であっても、逐次二軸延伸であってもよい。 As the polyamide film used in the present invention, a nylon film is generally used, and in particular, a nylon 6 film or a nylon 66 film is used. The thickness of the polyamide film is about 20 to 30 μm, and particularly 25 μm is used. The polyamide-based film is manufactured by a tubular method or a tenter method, and is generally manufactured by biaxial stretching. Biaxial stretching may be simultaneous biaxial stretching or sequential biaxial stretching.
ポリアミド系フィルムとアルミニウム箔とを接着する第一接着剤としては、従来公知のものが用いられるが、一般的にポリウレタン系接着剤が用いられる。第一接着剤の厚さは３〜７μｍ程度であり、一般的に５μｍ程度である。 As the first adhesive for adhering the polyamide-based film and the aluminum foil, a conventionally known one is used, but generally a polyurethane-based adhesive is used. The thickness of the first adhesive is about 3 to 7 μm, and generally about 5 μm.
アルミニウム箔も、従来公知のものが用いられるが、一般的に厚さが４０〜５０μｍ程度のものが用いられる。アルミニウム箔の合金組成も、従来公知のものが用いられるが、特に合金番号８０７９又は８０２１のものが用いられる。 A conventionally well-known aluminum foil is also used, but generally an aluminum foil having a thickness of about 40 to 50 μm is used. As the alloy composition of the aluminum foil, conventionally known ones are used, but those having an alloy number of 8079 or 8021 are particularly used.
アルミニウム箔とポリ塩化ビニル系フィルムとを接着する第二接着剤としても、従来公知のものが用いられるが、一般的にポリウレタン系接着剤が用いられる。特に、第二接着剤は前記した第一接着剤と同一のものを用いるのが好ましい。第二接着剤の厚さも３〜７μｍ程度であり、一般的に５μｍ程度である。特に、第二接着剤の厚さは、第一接着剤の厚さと同一にするのが好ましい。 A conventionally known adhesive is used as the second adhesive for adhering the aluminum foil and the polyvinyl chloride film, but a polyurethane adhesive is generally used. In particular, the second adhesive is preferably the same as the first adhesive described above. The thickness of the second adhesive is also about 3 to 7 μm, and is generally about 5 μm. In particular, the thickness of the second adhesive is preferably the same as the thickness of the first adhesive.
ポリ塩化ビニル系フィルムは、熱封緘層として用いられるものであり、従来公知のものが用いられる。ポリ塩化ビニル系フィルムの厚さは、５０〜７０μｍ程度のものが用いられ、特に６０μｍ程度のものが好ましく用いられる。 The polyvinyl chloride film is used as a heat sealing layer, and a conventionally known film is used. The thickness of the polyvinyl chloride film is about 50 to 70 μm, and particularly about 60 μm is preferably used.
本発明に係るアルミニウム箔製包装材料は、前記した、ポリアミド系フィルム，第一接着剤，アルミニウム箔，第二接着剤及びポリ塩化ビニル系フィルムの順に積層された積層体で構成されているものである。そして、この積層体は、その縦方向、横方向、４５°方向及び１３５°方向のいずれの方向においても、その伸びが１００〜１４０％の範囲内となるように設計されてなるものである。かかる積層体は、一般的に長尺状の巻物として提供されるものであり、縦方向とは長手方向のことを意味している。また、横方向とは幅方向のことであり、前記長手方向と直交する方向のことを意味している。４５°方向というのは、縦方向と横方向の中間であって右斜め方向のことである。また、１３５°方向というのは、縦方向と横方向の中間であって左斜め方向のことである。かかる各方向の伸びを測定するには、各方向が長手方向となる短冊片を採取して、この短冊片を引張試験機にて長手方向に引っ張ればよい。なお、ここでいう伸び（％）とは、［（破断時の短冊辺の長さ−当初の短冊片の長さ）／当初の短冊片の長さ］×１００で表されるものである。また、この伸びは後記するＬのことでもある。 The packaging material made of aluminum foil according to the present invention is composed of a laminate in which the polyamide film, the first adhesive, the aluminum foil, the second adhesive, and the polyvinyl chloride film are laminated in this order. is there. And this laminated body is designed so that the elongation may be in the range of 100 to 140% in any of the vertical direction, the horizontal direction, the 45 ° direction and the 135 ° direction. Such a laminate is generally provided as a long scroll, and the longitudinal direction means the longitudinal direction. Further, the lateral direction is the width direction and means a direction orthogonal to the longitudinal direction. The 45 ° direction is an intermediate direction between the vertical direction and the horizontal direction, and is an obliquely rightward direction. In addition, the 135 ° direction is an intermediate direction between the vertical direction and the horizontal direction, and is an oblique left direction. In order to measure the elongation in each direction, a strip piece in which each direction is the longitudinal direction is collected, and the strip piece is pulled in the longitudinal direction by a tensile tester. Here, the elongation (%) is expressed by [(length of strip side at break-length of original strip) / length of original strip] × 100. This elongation is also referred to as L described later.
積層体の伸びが１００％未満であると、成形性が悪く、成形時に割れが生じるので、好ましくない。また、積層体の伸びが１４０％を超えると、成形後において、所定の形状と異なる形状に変形しやすくなるので、好ましくない。 If the elongation of the laminate is less than 100%, the moldability is poor and cracking occurs during molding, which is not preferable. Further, if the elongation of the laminate exceeds 140%, it is not preferable because it tends to deform into a shape different from the predetermined shape after molding.
さらに、積層体のいずれの方向においても、ΔＥの値が０．５０〜０．６５の範囲内となるように設計されている。ここで、ΔＥとは、（Ｓ−Ｐ）／（Ｌ−０．２）で算出されるものであり、Ｓは破断時の応力（Ｎ／ｍｍ2）、Ｐは０．２％耐力（Ｎ／ｍｍ2）、Ｌは前記した伸び（％）を表している。Ｓは、前記した短冊片を引張試験機に掛けて短冊片が破断するときの荷重を読み取れば計算により、得られるものである。また、Ｐは、前記した短冊片を引張試験機に掛けて引張試験を行ない、短冊片が０．２％伸びたときの荷重を読み取れば計算により得られるものである。ここで、耐力を０．２％時の耐力としたのは、本発明で用いるアルミニウム箔の耐力は、一般的に０．２％伸びたときの応力に一致するからである。Ｌは前記した方法で得られる。なお、式中の０．２というのは、耐力に対応する伸びを表している。したがって、本発明で用いるΔＥは、積層体の耐力を超えた後におけるＳ−Ｓ曲線の傾きに相当するのである。 Furthermore, it is designed so that the value of ΔE is in the range of 0.50 to 0.65 in any direction of the laminate. Here, ΔE is calculated by (S−P) / (L−0.2), S is stress at break (N / mm 2 ), and P is 0.2% proof stress (N / Mm 2 ), L represents the above-described elongation (%). S is obtained by calculation if the strip strip is subjected to a tensile tester and the load when the strip breaks is read. Further, P is obtained by calculation by performing a tensile test by applying the above strip piece to a tensile tester and reading the load when the strip piece is extended by 0.2%. Here, the reason why the proof stress is 0.2% is that the proof stress of the aluminum foil used in the present invention is generally equal to the stress when it is extended by 0.2%. L is obtained by the method described above. Note that 0.2 in the formula represents elongation corresponding to the proof stress. Therefore, ΔE used in the present invention corresponds to the slope of the SS curve after exceeding the yield strength of the laminate.
積層体のΔＥの値が、０．５０未満であると、成形後において、変形しやすくなるので、好ましくない。また、積層体のΔＥの値が０．６５を超えると、成形時に割れが生じるので、好ましくない。 If the value of ΔE of the laminate is less than 0.50, it is not preferable because it tends to be deformed after molding. Further, if the value of ΔE of the laminate exceeds 0.65, it is not preferable because cracks occur during molding.
本発明に係るアルミニウム箔製包装材料は従来公知の包装体として成形しうるものである。特に、本発明に係るアルミニウム箔製包装材料は、プレススルーパック包装の容器本体として良好に成形しうるものである。本発明に係るアルミニウム箔製包装材料をプレススルーパック包装の容器本体のみに使用し、蓋材として従来公知の硬質アルミニウム箔を用いて、プレススルーパック包装を得ることができる。また、凹部を成形した本発明に係るアルミニウム箔製包装材料を二枚準備し、凹部を合致させて、その合致した凹部に錠剤等を収納した包装体としてもよい。なお、錠剤等を収納した後に、二枚の成形されたアルミニウム箔包装材料は、熱封緘層によって接着されることはいうまでもない。 The aluminum foil packaging material according to the present invention can be formed as a conventionally known package. In particular, the aluminum foil packaging material according to the present invention can be favorably molded as a container body for press-through pack packaging. The aluminum foil packaging material according to the present invention can be used only for a container body of press-through pack packaging, and a conventionally known hard aluminum foil can be used as a lid material to obtain a press-through pack packaging. Moreover, it is good also as a package which prepared two sheets of the aluminum foil packaging materials based on this invention which shape | molded the recessed part, matched the recessed part, and accommodated the tablet etc. in the matched recessed part. Needless to say, the two molded aluminum foil packaging materials are bonded by the heat sealing layer after the tablets and the like are stored.
本発明に係るアルミニウム箔製包装材料は、縦方向、横方向、４５°方向及び１３５°方向のいずれの方向においても、その伸びが１００〜１４０％の範囲内であり、かつ、ΔＥが０．５０〜０．６５の範囲内となっているので、成形時に割れが生じにくく、かつ、成形後において変形しにくいという効果を奏する。 The aluminum foil packaging material according to the present invention has an elongation in the range of 100 to 140% in any of the vertical direction, the horizontal direction, the 45 ° direction, and the 135 ° direction, and ΔE is 0.00. Since it is in the range of 50 to 0.65, there is an effect that cracking hardly occurs at the time of molding, and deformation hardly occurs after molding.

［積層体の評価］
（１）積層体の成形性：１０ｍｍφの雄型を用いてプラグアシスト成形を行い、一枚の積層体に深さ約３ｍｍのポケットを一定間隔を置いて成形したとき、各ポケットを構成している積層体に割れが生じるか否かを目視により、評価した。
（２）成形後における変形性：上記（１）で成形した成形体を二枚準備し、各ポケットが噛み合うように重ねた。この重ねたものを、さらに５枚（合計１０枚）重ねて、表裏から手で押さえつけた。この後、一枚ずつ成形体を剥がして、各ポケットの天面に変形が生じているかいなかを目視により、評価した。
[Evaluation of laminate]
(1) Formability of laminated body: When plug assist molding is performed using a male mold of 10 mmφ, and pockets of about 3 mm depth are formed at regular intervals on a single laminated body, each pocket is configured. It was visually evaluated whether or not the laminated body was cracked.
(2) Deformability after molding: Two molded articles molded in the above (1) were prepared and overlapped so that the pockets meshed. Five more (a total of 10) of this stack were stacked and pressed from the front and back by hand. Thereafter, the molded body was peeled off one by one, and it was visually evaluated whether or not the top surface of each pocket was deformed.
この結果、実施例１及び２に係る積層体は、ポケットにおいて割れが確認できず、また、ポケットの天面の変形も確認できないものであった。これに対して、比較例１に係る積層体は、ポケットにおいて割れは殆ど確認できなかったが、ポケットの天面に変形が確認された。比較例２に係る積層体は、ポケットの天面の変形は殆ど確認されなかったが、ポケットにおいて割れが確認された。 As a result, in the laminates according to Examples 1 and 2, no cracks could be confirmed in the pockets, and no deformation of the top surface of the pockets could be confirmed. On the other hand, in the laminate according to Comparative Example 1, almost no cracks were confirmed in the pockets, but deformation was confirmed on the top surface of the pockets. In the laminate according to Comparative Example 2, almost no deformation of the top surface of the pocket was confirmed, but cracks were confirmed in the pocket.
