Description

本発明は、食品、飲料品、医薬品、化粧品、化学品、工業製品等を包装する包装体の製造方法に関するものである。   The present invention relates to a method for producing a package for packaging foods, beverages, pharmaceuticals, cosmetics, chemicals, industrial products and the like.

従来、内側表面に撥水剤、防曇剤、帯電防止剤、難燃剤、無機充填剤、滑剤、導電剤、印刷インキ等を存在させ、所望の機能が付与された包装体が知られている。しかしながらこのような物質が包装体の内側表面に存在すると、これらが熱接着を阻害する物質（以下、熱接着阻害物質と称す）として作用するため、通常の熱接着方法を用いて包装体を製造すると、十分な熱接着強度が発現しないという問題があった。   Conventionally, a package having a desired function provided on the inner surface with a water repellent, an antifogging agent, an antistatic agent, a flame retardant, an inorganic filler, a lubricant, a conductive agent, printing ink, and the like is known. . However, if such substances are present on the inner surface of the package, they act as substances that inhibit thermal adhesion (hereinafter referred to as thermal adhesion inhibitors), so that the package is manufactured using the usual thermal bonding method. Then, there existed a problem that sufficient heat bond strength was not expressed.

このような中、特許文献１には、実質的に表面の大部分が接着阻害物質（フッ素系樹脂）層面である加工紙において、互いに対向する接着予定部分に接着阻害物質を欠く部分を有することを特徴とする製袋用加工紙が提案されている。この提案は包装袋に撥水性、撥油性を付与するために、包装袋の内側表面にフッ素系樹脂層を形成するにあたり、接着予定部分には接着阻害物質であるフッ素系樹脂層を設けないというものである。この提案によれば、接着予定部分に接着阻害物質層が形成されていない為、通常の接着方法を採用して、包装袋を製造することができる。   Under such circumstances, Patent Document 1 has a portion that lacks an adhesion inhibitory substance in a part of a bonding paper that faces each other in a processed paper whose surface is substantially the surface of an adhesion inhibitory substance (fluorine resin) layer. Processed paper for bag making featuring the above has been proposed. In this proposal, in order to impart water repellency and oil repellency to the packaging bag, when forming the fluororesin layer on the inner surface of the packaging bag, the adhesive planned portion is not provided with a fluororesin layer that is an adhesion inhibiting substance. Is. According to this proposal, since the adhesion-inhibiting substance layer is not formed on the portion to be bonded, a packaging bag can be manufactured using a normal bonding method.

実用新案登録第３０７０００９号公報Utility Model Registration No. 3070009

特許文献１記載の方法を採用すると、通常の接着方法にて包装袋を製造することはできる。しかしながら包装袋の内側端縁に接着予定部分が露出し、包装袋内縁に接着阻害物質が奏する機能（例えば、撥水性や撥油性）を備えない部分が形成されてしまうことがあった。
図５は、包装用フィルム５２の熱接着予定部５２ａ以外に熱接着阻害物質層５３が形成された包装用フィルム５２を用いて、従来の熱接着方法にて製造された包装体５１の平面図（Ａ）及びそのｚ−ｚ’端面の模式図（Ｂ）である。熱接着阻害物質層５３が形成されていない熱接着予定部５２ａと、実際の熱接着部５２ｂとの間に、熱接着阻害物質層５３が形成されていない機能欠落部５２ｃが存在する。該機能欠落部５２ｃは、熱接着阻害物質によって包装体内側表面に付与されるべき機能（撥水性、防曇性、帯電防止性、難燃性、滑性、導電性、意匠性等）が付与されていない。
本発明は、包装体内側表面に熱接着阻害物質層が形成された包装体において、このような機能欠落部が存在しない包装体を製造する方法の提供を目的とする。 If the method of patent document 1 is employ | adopted, a packaging bag can be manufactured with a normal adhesion method. However, a portion to be bonded is exposed at the inner edge of the packaging bag, and a portion having no function (for example, water repellency or oil repellency) played by the adhesion inhibiting substance may be formed at the inner edge of the packaging bag.
FIG. 5 is a plan view of a package 51 manufactured by a conventional thermal bonding method using a packaging film 52 in which a thermal adhesion inhibiting substance layer 53 is formed in addition to the thermal bonding planned portion 52a of the packaging film 52. It is a schematic diagram (B) of (A) and its zz 'end surface. Between the thermal bonding planned portion 52a where the thermal adhesion inhibiting substance layer 53 is not formed and the actual thermal bonding portion 52b, there is a function missing portion 52c where the thermal adhesion inhibiting substance layer 53 is not formed. The function deficient portion 52c is provided with a function (water repellency, antifogging property, antistatic property, flame retardancy, lubricity, conductivity, design, etc.) to be imparted to the inner surface of the package by the thermal adhesion inhibiting substance. It has not been.
An object of the present invention is to provide a method for producing a package in which such a lack of function does not exist in a package in which a thermal adhesion inhibiting substance layer is formed on the inner surface of the package.

本発明によると上記課題を解決するための手段として、熱接着予定部以外に、熱接着阻害物質層が形成された包装用フィルムを熱接着することによって包装体を製造する方法において、熱接着用冶具が、前記熱接着予定部を超えて、熱接着阻害物質層が形成された部分まで加熱及び加圧することを特徴とする包装体の製造方法が提供される。
また前記熱接着阻害物質層が撥水剤からなる層であることを特徴とする前記包装体の製造方法が提供される。
更に粘稠物品の包装に用いられることを特徴とする前記包装体の製造方法が提供される。 According to the present invention, as a means for solving the above-mentioned problem, in the method for manufacturing a package by thermally bonding a packaging film on which a thermal adhesion inhibiting substance layer is formed in addition to the thermal bonding scheduled portion, There is provided a method for manufacturing a package, wherein the jig heats and pressurizes a portion where the thermal adhesion inhibiting substance layer is formed beyond the thermal adhesion planned portion.
Further, there is provided the method for manufacturing the package, wherein the thermal adhesion inhibiting substance layer is a layer made of a water repellent.
Furthermore, the manufacturing method of the said package body characterized by using for the packaging of a viscous article is provided.

本発明の製造方法によると、熱接着用冶具が熱接着予定部を超えて熱接着阻害物質層上まで加熱・加圧するため、熱接着予定部は熱接着阻害物質層との境界部分まで熱接着される。そのため熱接着予定部と熱接着阻害物質層との間に機能欠落部が形成されず、熱接着阻害物質が奏する機能を、包装体内側表面の全域に付与することができる。
例えば、熱接着阻害物質が撥水剤である場合、包装体内側表面の端縁部にまで撥水性を付与することができる。そのため内容物を取り出す際に、包装体内側の端縁部に内容物が残留することを防止できる。特に、内容物がジャムや餡、バター、ヨーグルト等の粘稠物である場合、包装体の内側端縁部に内容物が残留しやすかったが、本発明の製造方法を採用するとこのような課題は解決する。 According to the manufacturing method of the present invention, the thermal bonding jig heats and presses the thermal bonding inhibitor layer beyond the thermal bonding planned portion, so that the thermal bonding planned portion is thermally bonded to the boundary portion with the thermal bonding inhibitor layer. Is done. Therefore, the lack of function part is not formed between the thermal adhesion scheduled part and the thermal adhesion inhibiting substance layer, and the function of the thermal adhesion inhibiting substance can be imparted to the entire area of the inner surface of the package.
For example, when the thermal adhesion inhibiting substance is a water repellent, water repellency can be imparted to the edge of the inner surface of the package. Therefore, when taking out the contents, it is possible to prevent the contents from remaining on the edge portion inside the package. In particular, when the content is a viscous material such as jam, straw, butter, yogurt, etc., the content was likely to remain on the inner edge of the package. Will solve.

図１は、本発明の製造方法に用いられる包装用フィルム１２の概略を示す断面図（模式図）である。本発明の包装用フィルム１２は、熱接着阻害物質層１３と基材フィルム１４とを備える。
熱接着阻害物質層１３は、基材フィルム１４に比較して熱接着性に劣ることを意味するものであり、必ずしも全く熱接着性を有さない層を意味するものではない。具体的には、撥水剤、防曇剤、帯電防止剤、難燃剤、無機充填剤、滑剤、導電剤、印刷インキ等の熱接着阻害物質からなる層を意味する。 FIG. 1 is a cross-sectional view (schematic diagram) showing an outline of a packaging film 12 used in the production method of the present invention. The packaging film 12 of the present invention includes a thermal adhesion inhibiting substance layer 13 and a base film 14.
The thermal adhesion-inhibiting substance layer 13 means that the thermal adhesiveness is inferior to that of the base film 14, and does not necessarily mean a layer having no thermal adhesiveness. Specifically, it means a layer made of a thermal adhesion inhibitor such as a water repellent, an antifogging agent, an antistatic agent, a flame retardant, an inorganic filler, a lubricant, a conductive agent, and printing ink.

基材フィルム１４は、図１に示すように少なくともシーラント層１４ａと耐熱層１４ｂとを備えるものが望ましい。
シーラント層１４ａは、例えば、低密度ポリエチレン、直鎖低密度ポリエチレン、超低密度ポリエチレン、高密度ポリエチレン、ポリプロピレン、エチレン−プロピレン共重合体、エチレン−酢酸ビニル共重合体、エチレン−不飽和カルボン酸共重合体、エチレン−不飽和カルボン酸エステル共重合体等の熱可塑性合成樹脂から形成される。中でも熱接着性、加工性の観点から低密度ポリエチレン、直鎖低密度ポリエチレン、超低密度ポリエチレン、高密度ポリエチレン、ポリプロピレン、エチレン−プロピレン共重合体が好適である。
耐熱層１４ｂは、シーラント層１４ａよりも耐熱性を有する樹脂から形成される層で、例えばポリエチレンテレフタレート、ポリブチレンテレフタレート、ポリアミド等から形成されるが、これらに限定されるものではない。 As shown in FIG. 1, the base film 14 preferably includes at least a sealant layer 14a and a heat-resistant layer 14b.
The sealant layer 14a is, for example, low density polyethylene, linear low density polyethylene, ultra low density polyethylene, high density polyethylene, polypropylene, ethylene-propylene copolymer, ethylene-vinyl acetate copolymer, ethylene-unsaturated carboxylic acid copolymer. It is formed from a thermoplastic synthetic resin such as a polymer or an ethylene-unsaturated carboxylic acid ester copolymer. Of these, low-density polyethylene, linear low-density polyethylene, ultra-low-density polyethylene, high-density polyethylene, polypropylene, and ethylene-propylene copolymer are preferable from the viewpoints of thermal adhesiveness and processability.
The heat-resistant layer 14b is a layer formed of a resin having heat resistance higher than that of the sealant layer 14a, and is formed of, for example, polyethylene terephthalate, polybutylene terephthalate, polyamide, or the like, but is not limited thereto.

また基材フィルム１４は、上記したようなシーラント層１４ａ、耐熱層１４ｂの他に、目的に応じて、アルミニウム箔、エチレン−酢酸ビニル共重合体ケン化物層、金属蒸着フィルム、金属酸化物蒸着フィルム、紙等を構成層として備えた積層体であってもよい。
また、基材フィルムの厚みは限定されるものではないが、１５〜３００μｍ、とりわけ３０〜１５０μｍが好適である。 In addition to the above-described sealant layer 14a and heat-resistant layer 14b, the base film 14 may be an aluminum foil, an ethylene-vinyl acetate copolymer saponified layer, a metal vapor deposition film, or a metal oxide vapor deposition film, depending on the purpose. Alternatively, a laminate including paper or the like as a constituent layer may be used.
Moreover, although the thickness of a base film is not limited, 15-300 micrometers, especially 30-150 micrometers are suitable.

次に実施例に基づき、本発明の包装体の製造方法を説明するが、本発明はこれに限定されるものではない。図２は、本発明の製造方法の一実施例を表す模式図である。
まず基材フィルム２４の片面に、熱接着阻害物質層２３が形成された包装用フィルム２２を製造する（図２（Ａ））。本実施例では、熱接着阻害物質として撥水剤を用い、熱接着阻害物質層２３の形成にはグラビア印刷法を用いた。尚、熱接着阻害物質層２３は、包装用フィルムの両側縁の熱接着予定部２２ａ−１、並びに巾方に延びる熱接着予定部２２ａ−２以外の部分に形成した。 Next, although the manufacturing method of the package of this invention is demonstrated based on an Example, this invention is not limited to this. FIG. 2 is a schematic view showing an embodiment of the production method of the present invention.
First, the packaging film 22 having the thermal adhesion inhibiting substance layer 23 formed on one surface of the base film 24 is manufactured (FIG. 2A). In this example, a water repellent was used as the thermal adhesion inhibiting substance, and a gravure printing method was used to form the thermal adhesion inhibiting substance layer 23. The thermal adhesion inhibiting substance layer 23 was formed on portions other than the thermal adhesion planned portion 22a-1 on both side edges of the packaging film and the thermal adhesion planned portion 22a-2 extending in the width direction.

次いで、包装用フィルム２２の両側縁の熱接着予定部２２ａ−１を重ねあわせ、熱接着用冶具２５にて、該熱接着予定部２２ａ−１を加熱ならびに加圧し、熱接着する（図２（Ｂ））。尚、このとき熱接着用冶具２５は、熱接着予定部２２ａ−１のみならず、該熱接着予定部２２ａ−１を超えて、隣接する熱接着阻害物質層２３上も加熱ならびに加圧する。図２（Ｂ）のｘ−ｘ’断面拡大図を図２（Ｂ）’に示す。一対の熱接着用冶具２５の下方端Ｌ１は、熱接着予定部２２ａ−１の下方端Ｌ２よりも、下（熱接着阻害物質層２３側）に位置している。そのため該熱接着予定部２２ａ−１は、熱接着阻害物質層２３との境界部分まで熱接着され、熱接着予定部２２ａ−１と熱接着阻害物質層２３との間に機能欠落部は形成されない。   Next, the thermal bonding scheduled portions 22a-1 on both side edges of the packaging film 22 are superposed, and the thermal bonding planned portion 22a-1 is heated and pressurized by the thermal bonding jig 25 to be thermally bonded (FIG. 2 ( B)). At this time, the thermal bonding jig 25 heats and pressurizes not only the thermal bonding scheduled portion 22a-1 but also the adjacent thermal bonding inhibiting substance layer 23 beyond the thermal bonding planned portion 22a-1. An x-x ′ cross-sectional enlarged view of FIG. 2B is shown in FIG. The lower ends L1 of the pair of heat bonding jigs 25 are located below (the heat bonding inhibitor layer 23 side) below the lower ends L2 of the heat bonding scheduled portions 22a-1. Therefore, the thermal bonding scheduled portion 22a-1 is thermally bonded up to the boundary portion with the thermal adhesion inhibiting substance layer 23, and no function loss portion is formed between the thermal bonding scheduled portion 22a-1 and the thermal adhesion inhibiting substance layer 23. .

両側縁の熱接着予定部２２ａ−１が熱接着されて、円筒状に成形された包装用フィルムは、次工程にて巾方向に熱接着される（図２（Ｃ））。本実施例では、熱接着用冶具２５’としてシールバー（図３（Ａ））を用いたが、例えば一定間隔毎に凸部を有する熱接着用ロール（図３（Ｂ））等を用いてもよい。巾方向の熱接着においても、熱接着用冶具２５’は巾方に延びる熱接着予定部２２ａ−２のみならず、該熱接着予定部２２ａ−２を超えて、隣接する熱接着阻害物質層２３上も加熱ならびに加圧する。更に本実施例では、巾方向の熱接着と同時に、切断用冶具２６にて円筒状の包装用フィルム２２を巾方向に切断し、袋の形状にする。   The packaging film formed in a cylindrical shape by thermally bonding the thermal bonding scheduled portions 22a-1 on both side edges is thermally bonded in the width direction in the next step (FIG. 2C). In this embodiment, a seal bar (FIG. 3A) is used as the thermal bonding jig 25 ′. However, for example, a thermal bonding roll (FIG. 3B) having convex portions at regular intervals is used. Also good. Also in the thermal bonding in the width direction, the thermal bonding jig 25 ′ is not limited to the thermal bonding planned portion 22 a-2 extending in the width direction, but beyond the thermal bonding planned portion 22 a-2, the adjacent thermal bonding inhibiting substance layer 23. The top is also heated and pressurized. Furthermore, in this embodiment, simultaneously with the thermal bonding in the width direction, the cylindrical packaging film 22 is cut in the width direction by the cutting jig 26 to form a bag shape.

最後に内容物を充填し、開口部を熱接着することにより本発明の包装体は完成する（図３（Ｄ））。むろん、該熱接着においても熱接着用冶具は、熱接着予定部を超えて、熱接着阻害物質層上も加熱ならびに加圧した。
尚、本実施例においてはすべての熱接着において、熱接着用冶具は熱接着予定部を超えて、隣接する熱接着阻害物質層上を加熱ならびに加圧したが、少なくとも一つの熱接着において、熱接着用冶具にて熱接着予定部を超えて加熱ならびに加圧することにより、本発明の効果を享受することができる。また、熱接着用冶具が加熱ならびに加圧する熱接着阻害物質層の幅は特に限定されないが、１〜２０ｍｍ程度が好ましく、特に１〜５ｍｍ程度が好ましい。１ｍｍ未満では十分な効果を得られない恐れがあり、２０ｍｍを超えても効果の向上は期待できない。 Finally, the contents are filled and the opening is thermally bonded to complete the package of the present invention (FIG. 3D). Of course, in the heat bonding, the heat bonding jig heated and pressed the heat bonding inhibitor layer beyond the heat bonding planned portion.
In this example, in all the thermal bonding, the thermal bonding jig heated and pressed the adjacent thermal bonding inhibitor layer beyond the thermal bonding planned portion, but in at least one thermal bonding, The effect of the present invention can be enjoyed by heating and pressurizing beyond the portion to be thermally bonded with the bonding jig. The width of the thermal adhesion inhibiting substance layer heated and pressed by the thermal bonding jig is not particularly limited, but is preferably about 1 to 20 mm, particularly preferably about 1 to 5 mm. If it is less than 1 mm, a sufficient effect may not be obtained, and if it exceeds 20 mm, improvement of the effect cannot be expected.

上述した実施例では、包装体の背面並びに上下端縁が熱接着されたいわゆるピロー包装体を製造したが、例えば図４（Ａ）に示す四方シールによる包装体、図４（Ｂ）に示す上下端縁と一方の側縁が熱接着された三方シールによる包装体、図４（Ｃ）に示す上下端縁のみが熱接着された包装体、更にはガゼット包装体、自立袋と呼ばれる包装体を製造しても良い。また熱接着阻害物質層が形成された基材フィルムを深絞り成形した包装体（図４（Ｄ））の周縁部を熱接着する際にも、本発明を適用することができる。
尚、熱接着阻害物質が例えば印刷インキ等で、尚且つ、図４（Ａ）（Ｄ）に示す包装体４１Ａ、４１Ｄのように、包装体が二枚の基材フィルムから形成されている場合において、少なくとも一方の基材フィルムのみに熱接着阻害物質層を形成すれば、目的とする機能を包装体に付与できる場合がある。そのような場合であっても、本発明を適用し、熱接着阻害物質層が形成された部分まで加熱及び加圧することにより、熱接着阻害物質層が形成された基材フィルムにおいて、機能欠落部が形成されることを防止ができる。 In the above-described embodiment, a so-called pillow package in which the back surface and upper and lower edges of the package are thermally bonded is manufactured. For example, a package with a four-side seal shown in FIG. 4 (A), upper and lower shown in FIG. 4 (B). A package with a three-side seal in which the edge and one side edge are thermally bonded, a package in which only the upper and lower edges shown in FIG. 4C are thermally bonded, a gusset package, and a package called a self-supporting bag It may be manufactured. The present invention can also be applied when thermally bonding the peripheral portion of a package (FIG. 4D) obtained by deep drawing a base film on which a thermal adhesion inhibiting substance layer is formed.
In the case where the thermal adhesion inhibiting substance is, for example, printing ink or the like, and the packaging body is formed of two base films as in the packaging bodies 41A and 41D shown in FIGS. In this case, if the thermal adhesion inhibiting substance layer is formed only on at least one base film, the intended function may be imparted to the package. Even in such a case, by applying the present invention and heating and pressing up to the portion where the thermal adhesion inhibiting substance layer is formed, in the base film on which the thermal adhesion inhibiting substance layer is formed, the function missing portion Can be prevented.

本発明は、包装体の内側表面に撥水剤、防曇剤、帯電防止剤、難燃剤、無機充填剤、滑剤、導電剤等の熱接着阻害物質が存在していても、十分な熱接着強度が確保できるとともに、熱接着阻害物質が奏する機能を、包装体の内縁部にまで付与することができる。
例えば熱接着阻害物質が撥水剤の場合、包装体の内側の縁端部にまで撥水性を付与することができる。よって内容物がジャムや餡、バター、ヨーグルト等の粘稠物質であり、スムーズな取り出しが困難な物質である場合に、特に好適に利用することができる。 The present invention provides sufficient thermal bonding even when a thermal adhesion inhibitor such as a water repellent, an antifogging agent, an antistatic agent, a flame retardant, an inorganic filler, a lubricant, or a conductive agent is present on the inner surface of the package. The strength can be secured and the function of the thermal adhesion inhibiting substance can be imparted to the inner edge of the package.
For example, when the thermal adhesion inhibiting substance is a water repellent, water repellency can be imparted to the inner edge of the package. Therefore, when the contents are viscous substances such as jam, candy, butter, yogurt and the like and are difficult to smoothly take out, the contents can be used particularly suitably.
