Description

本発明は、包装用フィルム及び包装袋に関する。 The present invention relates to packaging films and packaging bags.

特許文献１には、マヨネーズ、フラワーペースト、クリーム、ジャム等の粘稠性の食品等（以下「粘稠体」という。）を収容可能な包装袋が開示されている。 Patent Literature 1 discloses a packaging bag capable of containing viscous foods such as mayonnaise, flour paste, cream, and jam (hereinafter referred to as "viscous material").

特開２０１３－９５４８２号公報JP 2013-95482 A

特許文献１の包装袋は、フィルムを袋状にすることによって形成される。内容物がフラワーペーストである場合、包装袋を開封して、フラワーペーストが平坦なフィルム上に載置されている状態とし、この状態からフィルムを反転させることによって、フラワーペーストを混練装置の投入口等に落下させることによって、フラワーペーストが包装袋から取り出される。混練装置では、フラワーペーストがパン生地等と共に混練される。 The packaging bag of Patent Document 1 is formed by making a film into a bag shape. When the content is flour paste, the packaging bag is opened so that the flour paste is placed on a flat film, and the film is turned over from this state to transfer the flour paste to the inlet of the kneading device. The flour paste is taken out of the packaging bag by dropping it on a similar surface. In the kneading device, flour paste is kneaded together with bread dough and the like.

フラワーペーストは、全量がフィルムから離れることが要求されており、フラワーペーストはフィルムに付着しやすい性質を有しており、フラワーペーストの身離れ性（フィルムからの離れやすさの度合い）を向上させることが容易ではない。 The entire amount of the flower paste is required to be separated from the film, and the flower paste has the property of easily adhering to the film, and the releasability of the flower paste (degree of ease of separation from the film) is improved. It is not easy.

本発明はこのような事情に鑑みてなされたものであり、フラワーペーストの身離れ性を向上させることが可能な包装用フィルムを提供するものである。 SUMMARY OF THE INVENTION The present invention has been made in view of such circumstances, and provides a packaging film capable of improving the release property of flour paste.

本発明によれば、基材層及びシール層をこの順に備える包装用フィルムであって、前記シール層は、内容物に接触する接触層を有し、前記接触層は、熱可塑性樹脂と、帯電防止剤と、潤滑剤を含む、包装用フィルムが提供される。 According to the present invention, there is provided a packaging film comprising a substrate layer and a sealing layer in this order, wherein the sealing layer has a contact layer that contacts contents, and the contact layer comprises a thermoplastic resin and an electrifying A packaging film is provided that includes an inhibitor and a lubricant.

本発明者は鋭意検討を行ったところ、上記構成を有する包装用フィルムにおいて、帯電防止剤と潤滑剤を接触層に併存させることによってフラワーペーストの身離れ性を向上させることができることを見出し、本発明の完成に到った。 As a result of intensive studies, the inventors of the present invention found that in the packaging film having the above configuration, the ability to separate the flour paste from the flour paste can be improved by coexisting the antistatic agent and the lubricant in the contact layer. The invention has been perfected.

なお、フラワーペーストとは、小麦粉、澱粉、ナッツ類もしくはその加工品、ココア、チョコレート、コーヒー、果肉または果汁、いも類、豆類または野菜類を主原料とし、これに砂糖、油脂、粉乳、卵、小麦粉などを加え加熱殺菌処理をしてペースト状にし、パンまたは菓子に充填または塗布して食用に供するものを意味する。 Flour paste is mainly composed of wheat flour, starch, nuts or their processed products, cocoa, chocolate, coffee, pulp or fruit juice, potatoes, beans or vegetables, and is added with sugar, oil, milk powder, eggs, It means that wheat flour or the like is added and heat sterilized to make a paste, which is then filled or applied to bread or confectionery and served as food.

以下、本発明の実施形態について説明する。以下に示す実施形態中で示した各種特徴事項は、互いに組み合わせ可能である。また、各特徴事項について独立して発明が成立する。 Embodiments of the present invention will be described below. Various features shown in the embodiments shown below can be combined with each other. In addition, the invention is established independently for each characteristic item.

１．包装用フィルム１
図１に示すように、本発明の一実施形態の包装用フィルム１は、基材層２及びシール層３をこの順に備える。 1. packaging film 1
As shown in FIG. 1, the packaging film 1 of one embodiment of the present invention comprises a substrate layer 2 and a seal layer 3 in this order.

基材層２は、無延伸ポリアミド、延伸ポリアミド、エチレン－αオレフィン共重合体、ポリプロピレン、高密度ポリエチレン、線状低密度ポリエチレン、ナイロンなどの樹脂で構成する。基材層２は、１０～３０μｍの厚さで構成することが好ましく、１５～２５μｍの厚さで構成することが更に好ましい。基材層２は、ポリ塩化ビニリデンなどで構成されたバリア層でコーティングされていてもよい。 The base material layer 2 is made of resin such as unstretched polyamide, stretched polyamide, ethylene-α-olefin copolymer, polypropylene, high-density polyethylene, linear low-density polyethylene, and nylon. The base layer 2 preferably has a thickness of 10 to 30 μm, more preferably 15 to 25 μm. The substrate layer 2 may be coated with a barrier layer made of polyvinylidene chloride or the like.

シール層３は、ヒートシール性の有する層であり、熱可塑性樹脂で構成される。熱可塑性樹脂としては、ヒートシール性の良好な材料としては、例えば、公知の低密度ポリエチレン、線状低密度ポリエチレン、中密度ポリエチレン、高密度ポリエチレン、プロピレン－エチレン共重合体、その他エチレン系不飽和カルボン酸乃至その無水物でグラフト変性されたオレフィン樹脂等のオレフィン系樹脂、比較的低融点乃至低軟化点のポリアミド系樹脂、ポリエステル系樹脂、エチレン－酢酸ビニル共重合体樹脂等が挙げられる。シール層３は、３０～６０μｍの厚さで構成することが好ましく、４０～５０μｍの厚さで構成することが更に好ましい。 The sealing layer 3 is a layer having heat-sealing properties and is made of a thermoplastic resin. Examples of thermoplastic resins that have good heat-sealing properties include known low-density polyethylene, linear low-density polyethylene, medium-density polyethylene, high-density polyethylene, propylene-ethylene copolymer, and other ethylenically unsaturated resins. Examples thereof include olefin resins such as olefin resins graft-modified with carboxylic acid or its anhydride, polyamide resins, polyester resins, ethylene-vinyl acetate copolymer resins, etc. having relatively low melting points or low softening points. The seal layer 3 preferably has a thickness of 30 to 60 μm, more preferably 40 to 50 μm.

シール層３は、内容物に接触する接触層３ａを有する。接触層３ａは、熱可塑性樹脂と、帯電防止剤と、潤滑剤を含む。帯電防止剤は、帯電防止性を付与可能な添加剤であり、潤滑剤は、潤滑性を付与可能な添加剤である。後述する実施例・比較例で示すように、帯電防止剤と潤滑剤を接触層３ａに併存させることによってフラワーペーストの身離れ性が大幅に向上する。 The sealing layer 3 has a contact layer 3a that contacts the contents. The contact layer 3a contains a thermoplastic resin, an antistatic agent, and a lubricant. An antistatic agent is an additive capable of imparting antistatic properties, and a lubricant is an additive capable of imparting lubricity. As will be shown in Examples and Comparative Examples to be described later, the coexistence of the antistatic agent and the lubricant in the contact layer 3a significantly improves the releasability of the flour paste.

接触層３ａの熱可塑性樹脂は、低密度ポリエチレンとポリブテンを含むことが好ましい。この場合、シール層３のイージーピール性（シール部分が人力で剥離させやすさの度合い）が良好になりやすいからである。接触層３ａは、シール強度が３～１０Ｎ／１５ｍｍとなるように組成を調整することが好ましい。 The thermoplastic resin of the contact layer 3a preferably contains low density polyethylene and polybutene. This is because in this case, the easy peelability of the seal layer 3 (the degree of ease with which the seal portion can be peeled off manually) tends to be improved. The composition of the contact layer 3a is preferably adjusted so that the seal strength is 3 to 10 N/15 mm.

帯電防止剤は、グリセリン脂肪酸エステルとポリグリセリン脂肪酸エステルを含むことが好ましい。帯電防止剤の一例は、ＲＩＫＥＭＡＳＴＥＲ ＥＳＲ－７９３である。接触層３ａを構成する樹脂組成物の全体を１００質量％とすると、帯電防止剤の配合割合は、５～１２質量％が好ましく、６～９質量％がさらに好ましく、具体的には例えば、５、５．５、６、６．５、７、７．５、８、８．５、９、９．５、１０、１０．５、１１、１１．５、１２質量％であり、ここで例示した数値の何れか２つの間の範囲内であってもよい。帯電防止剤は、４．５質量％程度配合することが一般的であるが、本実施形態では、帯電防止剤の配合割合を通常よりも高くすることによって身離れ性の向上を顕著にしている。また、帯電防止剤の配合割合が大きすぎると、フィルム製袋時に目詰まりを起こす虞がある。 The antistatic agent preferably contains glycerin fatty acid esters and polyglycerin fatty acid esters. An example of an antistatic agent is RIKEMASTER ESR-793. Assuming that the total resin composition constituting the contact layer 3a is 100% by mass, the mixing ratio of the antistatic agent is preferably 5 to 12% by mass, more preferably 6 to 9% by mass. , 5.5, 6, 6.5, 7, 7.5, 8, 8.5, 9, 9.5, 10, 10.5, 11, 11.5, 12% by weight, exemplified here It may be in a range between any two of the numbers given. Antistatic agent is generally blended about 4.5% by mass, but in the present embodiment, the antistatic agent blending ratio is higher than usual, thereby significantly improving the separation property. . On the other hand, if the proportion of the antistatic agent is too large, clogging may occur during film bag making.

潤滑剤は、脂肪酸アミドを含むことが好ましい。脂肪酸アミドは、オレイン酸アミドとエルカ酸アミドを含むことが好ましい。これらの化合物からなる帯電防止剤及び潤滑剤を用いることによって身離れ性の向上が顕著になる。 Preferably, the lubricant contains fatty acid amides. Fatty acid amides preferably include oleic acid amide and erucic acid amide. By using an antistatic agent and a lubricant comprising these compounds, the improvement in detachability becomes remarkable.

シール層３は、単層又は多層で構成される。シール層３が単層である場合、シール層３の全体が接触層３ａとなる。 The sealing layer 3 is composed of a single layer or multiple layers. When the sealing layer 3 is a single layer, the entire sealing layer 3 becomes the contact layer 3a.

シール層３が多層構成の場合、シール層３全体の厚さに対する接触層３ａの厚さの割合は、１０～５０％が好ましく、２０～４０％がさらに好ましい。 When the seal layer 3 has a multilayer structure, the ratio of the thickness of the contact layer 3a to the thickness of the entire seal layer 3 is preferably 10 to 50%, more preferably 20 to 40%.

シール層３が多層構成である場合、シール層３は、接触層３ａとポリエチレン層３ｂを備えることが好ましい。ポリエチレン層３ｂは、接触層３ａ側から順にＬＬＤＰＥ層３ｂ１及びＬＤＰＥ層３ｂ２を備えることが好ましい。シール層３を多層構成にすることによって、十分なヒートシール性を確保しつつ、接触層３ａによってイージーピール性及び身離れ性を発揮させることが可能になる。ポリエチレン層３ｂ全体の厚さに対するＬＤＰＥ層３ｂ２の厚さの割合は、２０～８０％が好ましく、３０～７０％がさらに好ましく、４０～６０％がさらに好ましい。 If the sealing layer 3 is of multilayer construction, it preferably comprises a contact layer 3a and a polyethylene layer 3b. The polyethylene layer 3b preferably comprises an LLDPE layer 3b1 and an LDPE layer 3b2 in order from the contact layer 3a side. By forming the seal layer 3 into a multi-layered structure, it is possible to ensure sufficient heat-sealing properties and exhibit easy-peelability and separability through the contact layer 3a. The ratio of the thickness of the LDPE layer 3b2 to the thickness of the entire polyethylene layer 3b is preferably 20-80%, more preferably 30-70%, and even more preferably 40-60%.

シール層３を構成するフィルムは、インフレーション成形によって形成することが好ましい。インフレーション成形によって形成されたフィルムは、偏肉やミクロ単位での凹凸が存在している場合が多いので、帯電防止剤と潤滑剤を接触層３ａに併存させてフラワーペーストの身離れ性を向上させることの技術的意義が特に顕著である。 The film forming the sealing layer 3 is preferably formed by inflation molding. Films formed by inflation molding often have unevenness in thickness and microscopic unevenness, so an antistatic agent and a lubricant are coexisted in the contact layer 3a to improve the separation of the flour paste. The technical significance of this is particularly conspicuous.

フィルム１は、基材層２を構成するフィルムと、シール層３を構成するフィルムをドライラミネート法や押出ラミネート法等によって積層することによって製造可能である。基材層２とシール層３の間に接着層４を設けてもよい。接着層は、ポリウレタン系接着剤等で構成可能である。また、基材層２には、シール層３側の面に印刷処理を施してもよい。 The film 1 can be produced by laminating a film forming the base layer 2 and a film forming the seal layer 3 by dry lamination, extrusion lamination, or the like. An adhesive layer 4 may be provided between the base material layer 2 and the sealing layer 3 . The adhesive layer can be composed of a polyurethane-based adhesive or the like. In addition, the base material layer 2 may be printed on the surface on the seal layer 3 side.

フィルム１の摩擦係数は、０．１５～０．２０であることが好ましい。フラワーペーストの製造工場は高温多湿である場合があり、フィルム１の摩擦係数が大きすぎるとフィルム１を機械に通したときに引っかかりが発生する場合がある。一方、フィルム１の摩擦係数が小さすぎると、包装用フィルム１を機械に通したときに空回りが発生して、製造がストップする虞がある。 The coefficient of friction of the film 1 is preferably 0.15-0.20. The flour paste manufacturing factory may be hot and humid, and if the coefficient of friction of the film 1 is too high, the film 1 may get stuck when passed through a machine. On the other hand, if the coefficient of friction of the film 1 is too small, idling may occur when the packaging film 1 is passed through a machine, and production may stop.

２．包装袋１１
図２に示すように、本発明の一実施形態の包装袋１１は、フィルム１が袋状にされて構成される。 2. packaging bag 11
As shown in FIG. 2, a packaging bag 11 according to one embodiment of the present invention is configured by forming a film 1 into a bag shape.

包装袋１１は、縦シール部１２と、横シール部１３，１４を備える。縦シール部１２は、フィルム１を筒状に湾曲させてフィルム１の両端のシール層３同士を重ね合わせた状態で、重ね合わせた部分１５を端縁部を除いて帯状にヒートシールすることによって形成することができる。上記端縁部が、縦シール部１２に隣接した引き剥がし部１６，１７となる。引き剥がし部１６，１７を把持して引っ張ることによって縦シール部１２を容易に剥離させることができる。 The packaging bag 11 has a vertical seal portion 12 and horizontal seal portions 13 and 14 . The vertical seal portion 12 is formed by bending the film 1 into a tubular shape, overlapping the seal layers 3 at both ends of the film 1, and heat-sealing the overlapped portion 15 in a band shape except for the edge portions. can be formed. The above-mentioned edge portions become tear-off portions 16 and 17 adjacent to the longitudinal seal portion 12 . By gripping and pulling the peeling portions 16 and 17, the vertical seal portion 12 can be easily peeled off.

横シール部１３，１４は、縦シール部１２を形成後の筒状のフィルム１に対して、縦シール部１２に直交する方向において、対向するシール層３同士を帯状にヒートシールすることによって形成することができる。横シール部１３を形成した後に、筒状のフィルム１内にフラワーペーストを充填し、その後、横シール部１４を形成することによって、フラワーペーストを包装袋１１内に封入することができる。 The lateral seal portions 13 and 14 are formed by heat-sealing the sealing layers 3 facing each other in a strip shape in a direction orthogonal to the longitudinal seal portion 12 with respect to the cylindrical film 1 after the longitudinal seal portion 12 is formed. can do. Flour paste can be enclosed in the packaging bag 11 by filling the tubular film 1 with flour paste after forming the lateral seal portion 13 and then forming the lateral seal portion 14 .

フラワーペーストは、縦シール部１２と横シール部１３，１４を剥離することによって包装袋１１から取り出すことが可能である。縦シール部１２と横シール部１３，１４は、人力で剥離可能であるので、ハサミやカッターを用いることなく、フラワーペーストの取り出しが可能である。 The flour paste can be taken out from the packaging bag 11 by peeling off the vertical seal portion 12 and the horizontal seal portions 13 and 14 . Since the vertical seal portion 12 and the horizontal seal portions 13 and 14 can be peeled off manually, the flour paste can be taken out without using scissors or a cutter.

また、縦シール部１２と横シール部１３，１４を剥離することによって包装袋１１を開封すると、フラワーペーストが平坦なフィルム１上に載置されている状態となる。この状態からフィルム１を反転させることによって、フラワーペーストを混練装置の投入口等に落下させることによって、フラワーペーストに手を触れることなく、フラワーペーストを包装袋から取り出すことができる。この場合、フィルム１にフラワーペーストが残存することが懸念されるが、本実施形態のフィルム１は、帯電防止剤と潤滑剤を接触層３ａに併存させることによってフラワーペーストの身離れ性が向上しているので、フィルム１上にフラワーペーストが残留することが抑制される。 When the packaging bag 11 is opened by peeling off the vertical seal portion 12 and the horizontal seal portions 13 and 14 , the flour paste is placed on the flat film 1 . By inverting the film 1 from this state, the flour paste can be dropped into the input port of the kneading device or the like, so that the flour paste can be taken out from the packaging bag without touching the flour paste. In this case, there is concern that the flour paste may remain on the film 1, but in the film 1 of the present embodiment, the antistatic agent and the lubricant are coexistent in the contact layer 3a, so that the flour paste can be easily removed. Therefore, it is possible to prevent the flour paste from remaining on the film 1 .

１．実施例・比較例
＜実施例１＞
図１に示す層構成のフィルム１を用いて、図２に示す形状の包装袋１１を作製した。縦シール部１２及び横シール部１３においてヒートシールを行った後の筒状のフィルム１内にフラワーペーストを充填し、その後、横シール部１４においてヒートシールを行うことによって、包装袋１１内に、フラワーペーストを封入した。フィルム１の製袋及びフラワーペーストの充填時の環境は、湿度８０％以上、室温４０℃以上であった。 1. Examples/Comparative Examples <Example 1>
Using the film 1 having the layer structure shown in FIG. 1, a packaging bag 11 having the shape shown in FIG. 2 was produced. Flour paste is filled in the cylindrical film 1 after heat sealing at the vertical sealing portion 12 and the horizontal sealing portion 13, and then heat sealing is performed at the horizontal sealing portion 14, so that the packaging bag 11 contains: Flour paste was enclosed. The environment during bag making of Film 1 and filling with flour paste was humidity of 80% or higher and room temperature of 40° C. or higher.

接触層３ａを構成する樹脂組成物の組成は、以下の通りである。
・ＬＤＰＥ：１８．７０質量％
・ＬＬＤＰＥ：４８．６０質量％
・ポリブテン含有添加剤（ＴＡＦＭＥＲ ＢＬ３４５０、三井化学製）：２４．３０質量％
・帯電防止剤：７．５質量％
・潤滑剤：０．９質量％ The composition of the resin composition forming the contact layer 3a is as follows.
・LDPE: 18.70% by mass
・LLDPE: 48.60% by mass
· Polybutene-containing additive (TAFMER BL3450, manufactured by Mitsui Chemicals): 24.30% by mass
・Antistatic agent: 7.5% by mass
・ Lubricant: 0.9% by mass

帯電防止剤としては、グリセリン脂肪酸エステルとポリグリセリン脂肪酸エステルを含む帯電防止剤であるＲＩＫＥＭＡＳＴＥＲ ＥＳＲ－７９３を用いた。潤滑剤としては、脂肪酸アミド（オレイン酸アミドとエルカ酸アミド）を含む潤滑剤を用いた。 As an antistatic agent, RIKEMASTER ESR-793, which is an antistatic agent containing glycerin fatty acid ester and polyglycerin fatty acid ester, was used. Lubricants containing fatty acid amides (oleic acid amide and erucic acid amide) were used as lubricants.

製造から６日経過後に、縦シール部１２と横シール部１３，１４を剥離することによって包装袋１１を開封してフラワーペーストが平坦なフィルム１上に載置されている状態とし、その状態からフィルム１を反転させてフラワーペーストを落下させた。 After 6 days have passed since the manufacture, the packaging bag 11 is opened by peeling off the vertical seal portion 12 and the horizontal seal portions 13 and 14 so that the flour paste is placed on the flat film 1, and from this state. Film 1 was inverted to allow the flour paste to fall.

フィルム１上にはフラワーペーストが残留しておらず、フィルム１からのフラワーペーストの身離れ性が良好であることがわかった。 No flour paste remained on the film 1, and it was found that the flour paste was easily separated from the film 1.

＜比較例１＞
接触層３ａが帯電防止剤を含まない点以外は、実施例１と同様の方法で、フラワーペーストが封入された包装袋１１を作製し、包装袋１１を開封してフラワーペーストを落下させた。 <Comparative Example 1>
A packaging bag 11 containing flour paste was prepared in the same manner as in Example 1 except that the contact layer 3a did not contain an antistatic agent, and the packaging bag 11 was opened to drop the flour paste.

包装袋１１にはフラワーペーストが部分的に残留しており、フィルム１からのフラワーペーストの身離れ性が不十分であった。 The flour paste partially remained in the packaging bag 11, and the separation of the flour paste from the film 1 was insufficient.

＜比較例２＞
接触層３ａが潤滑剤を含まない点以外は、実施例１と同様の方法で、フラワーペーストが封入された包装袋１１を作製し、包装袋１１を開封してフラワーペーストを落下させた。 <Comparative Example 2>
A packaging bag 11 containing flour paste was prepared in the same manner as in Example 1 except that the contact layer 3a did not contain a lubricant, and the packaging bag 11 was opened to drop the flour paste.

包装袋１１にはフラワーペーストが部分的に残留しており、フィルム１からのフラワーペーストの身離れ性が不十分であった。 The flour paste partially remained in the packaging bag 11, and the separation of the flour paste from the film 1 was insufficient.

２．考察
上記実施例・比較例で示すように、接触層３ａに帯電防止剤と潤滑剤の両方を添加した場合にのみ、フィルム１からのフラワーペーストの身離れ性が良好になることが分かった。 2. DISCUSSION As shown in the above examples and comparative examples, it was found that the flour paste can be easily separated from the film 1 only when both the antistatic agent and the lubricant are added to the contact layer 3a.
