Abstract
Description
本発明は、芳香剤などの蒸散性内容物を効果的に包装、使用可能とするフィルム、および包装体に関するものである。 The present invention relates to a film and a package that enable effective packaging and use of transpirationable contents such as fragrances.
従来、芳香剤など（中でも液状、ゲル状の薬液）をガスバリア性フィルムを用いた容器に収納し、開封時にガスバリア層側とガス透過性シール層側を剥離すると、内容薬液が残ったガス透過性シール層を介して透過、蒸散することにより、薬液成分を効率的に使用することが一般的に知られている（特許文献１〜３）。 Conventionally, fragrances (especially liquid or gel chemicals) are stored in a container using a gas barrier film, and when the gas barrier layer side and gas permeable seal layer side are peeled off when opened, the gas permeability remains. It is generally known that chemical liquid components are used efficiently by permeation and evaporation through a seal layer (Patent Documents 1 to 3).
しかしながら、容器開封時にガスバリア層とガス透過性シール層を剥離する際、剥離強度が強くなりすぎ、ガス透過性シール層が破断し、亀裂等生ずることがあり、内容薬液が漏洩するなどの問題もしばしば見受けられる。 However, when the gas barrier layer and the gas permeable seal layer are peeled off when the container is opened, the peel strength becomes too strong, the gas permeable seal layer may be broken and cracks may occur, and the content chemical solution may leak. Often seen.
前述のような開封時にガス透過性シール層が破断する要因としては、容器製造時のヒートシール工程において、ガス透過性シール層に過度なシール熱、シール圧が加わることで容器フランジのシール際にガス透過性シール層の樹脂溜りが発生しやすくなるため、容器開封時に樹脂溜りが負荷をかけ、ガス透過性シール層が破断する、ないしは、ヒートシール時にヒートシール面に過度なシール熱、シール圧が加わることで、ガス透過性シール層の粘着性が増し、フィルム製造時よりもガスバリア層との剥離強度が強くなるため、容器開封時の負荷が強くなり、ガス透過性シール層が破断する、といったことが挙げられる。 The reason why the gas permeable sealing layer breaks at the time of opening as described above is that when the container flange is sealed by applying excessive sealing heat and pressure to the gas permeable sealing layer in the heat sealing process at the time of manufacturing the container. Resin accumulation in the gas permeable seal layer is likely to occur, so that the resin reservoir is loaded when the container is opened, and the gas permeable seal layer breaks, or excessive heat and pressure are applied to the heat seal surface during heat sealing. Is added, the adhesiveness of the gas permeable seal layer is increased, the peel strength with the gas barrier layer is stronger than during film production, the load when opening the container is increased, and the gas permeable seal layer is broken, And so on.
ガス透過性シール層が破断すると、内容薬液成分の効率的な使用ができず、また人体などへの付着による健康被害、使用箇所周辺の変色、汚染なども発生しうるため、当該機能性容器商品（芳香剤など）としては、極力不具合製品の発生を抑える必要がある。 If the gas-permeable sealing layer breaks, the contents of the chemical components cannot be used efficiently, and health damage due to adhesion to the human body, discoloration around the use location, contamination, etc. may occur. As a fragrance, it is necessary to suppress the occurrence of defective products as much as possible.
しかしながら、現実的には実際に容器を開封するまで破断しやすいのかどうかを判断することは非常に困難、かつ煩雑で、生産効率が極めて落ちる。 However, in reality, it is very difficult and cumbersome to determine whether the container is easily broken until the container is actually opened, and the production efficiency is extremely lowered.
本発明は、上記実情に鑑みなされたものであり、その解決課題は、芳香剤など（特に液状、ゲル状）の飛散性内容物を効果的に包装、使用可能とするフィルム、および包装体を提供することにある。 This invention is made | formed in view of the said situation, The solution subject is the film which makes it possible to effectively wrap and use the fragrance | flavor etc. (especially liquid, gel-like) scattering contents, and a package. It is to provide.
本発明者は、上記課題に鑑み鋭意検討した結果、特定の構成を採用すれば、上記課題を容易に解決できることを見いだし、本発明を完成するに至った。 As a result of intensive studies in view of the above problems, the present inventor has found that the above problems can be easily solved by adopting a specific configuration, and the present invention has been completed.
すなわち、本発明の要旨は、ガス透過性シール層とガスバリア層と、両層の間に少なくとも１層の易剥離層とを有することを特徴とする易剥離性多層フィルム、当該易剥離性多層フィルムの外側に、延伸フィルムおよび金属箔を、ドライラミネートまたは押出ラミネートにより積層してなることを特徴とするラミネート多層フィルム、および前記多層フィルムを使用してなることを特徴とする包装体に存する。 That is, the gist of the present invention is an easily peelable multilayer film comprising a gas permeable seal layer, a gas barrier layer, and at least one easily peelable layer between both layers, and the easily peelable multilayer film. The laminated multilayer film is characterized in that a stretched film and a metal foil are laminated on the outside of the laminate by dry lamination or extrusion lamination, and a package comprising the multilayer film.
本発明によれば、芳香剤など（特に液状、ゲル状）の飛散性内容物を効果的に包装、使用可能とするフィルム、および包装体を提供することができ、本発明の工業的価値は高い。 According to the present invention, it is possible to provide a film and a package that can effectively wrap and use scentable contents such as fragrances (particularly liquid or gel), and a package, and the industrial value of the present invention is high.
本発明において、易剥離層とは、例えば、ポリエチレン系樹脂および無水マレイン酸変性樹脂を含む樹脂組成物からなり、ポリエチレン系樹脂が通常９８〜５５重量％、好ましくは９５〜７５重量％、より好ましくは９３〜８８重量％、無水マレイン酸変性エチレン系樹脂が通常２〜４５重量％、好ましくは５〜２５重量％、より好ましくは７〜１２重量％であり、ガスバリア層は、例えば、エチレン−ビニルアルコール共重合体系樹脂、ポリアミド系樹脂組成物等からなることが好ましく、ガス透過性シール層は、例えば、低密度ポリエチレン系樹脂、直鎖上低密度ポリエチレン系樹脂、エチレン−酢酸ビニル共重合体系樹脂などのポリエチレン系樹脂、ないしその共重合体系樹脂からなることが好ましい。 易剥離層に含まれるポリエチレン系樹脂としては、ＤＳＣ（示唆走査熱量分析）による融点が通常１００℃以上、好ましくは１１５℃以上、より好ましくは１２０℃以上、かつ密度が通常０．９２５〜０．９５５ｇ／ｃｍ３、好ましくは０．９３０〜０．９４０ｇ／ｃｍ３、より好ましくは０．９３０〜０．９３５ｇ／ｃｍ３であることを特徴とする。 In the present invention, the easy release layer is composed of, for example, a resin composition containing a polyethylene resin and a maleic anhydride-modified resin, and the polyethylene resin is usually 98 to 55% by weight, preferably 95 to 75% by weight, more preferably. 93 to 88% by weight, maleic anhydride-modified ethylene resin is usually 2 to 45% by weight, preferably 5 to 25% by weight, more preferably 7 to 12% by weight. The gas barrier layer may be, for example, ethylene-vinyl. It is preferably made of an alcohol copolymer resin, a polyamide resin composition, etc., and the gas permeable sealing layer is, for example, a low density polyethylene resin, a linear low density polyethylene resin, or an ethylene-vinyl acetate copolymer resin. It is preferable that it consists of polyethylene-type resin, such as these, or its copolymer type resin. As the polyethylene resin contained in the easy release layer, the melting point by DSC (suggested scanning calorimetry) is usually 100 ° C. or higher, preferably 115 ° C. or higher, more preferably 120 ° C. or higher, and the density is usually 0.925-0. 955 g / cm 3 , preferably 0.930 to 0.940 g / cm 3 , more preferably 0.930 to 0.935 g / cm 3 .
易剥離層に含まれるポリエチレン系樹脂の融点、密度を一般的なポリエチレンの中でも高めの物性値を選定することで、容器製造時のヒートシール工程における粘着接着力が抑えられ、ヒートシール後もガスバリア層との剥離強度が強くなりすぎず、ガス透過性シール層を破断することなく開封できる。 By selecting the higher physical properties of polyethylene-based resin contained in the easy-release layer, the higher adhesion value in general polyethylene, the adhesive strength in the heat-sealing process at the time of container production can be suppressed, and even after heat sealing, the gas barrier The peel strength from the layer does not become too strong, and the gas permeable sealing layer can be opened without breaking.
一方でさらに高密度のポリエチレンを使用したり、ポリプロピレン系樹脂による易剥離層処方をしてしまったりすると、やや開封時の手剥離感がスリップスティック気味となり、商品品質としては若干劣ることとなる。 On the other hand, if a higher density polyethylene is used or an easy release layer is formulated with a polypropylene-based resin, the hand-peeling feeling at the time of opening becomes slightly slipstick, and the product quality is slightly inferior.
本発明の包装体は、本発明の易剥離性多層フィルムを用いたドライラミネートフィルムを蓋材として用い、底材としてたとえばポリエステル系樹脂製シートなどを熱成型してなる容器とをヒートシールしてなる包装体であることが好ましいが、特に包装体の材質、製造方法を限定することはない。 The package of the present invention uses a dry laminate film using the easily peelable multilayer film of the present invention as a lid, and heat seals a container formed by thermoforming, for example, a polyester resin sheet as a bottom material. However, the material of the package and the manufacturing method are not particularly limited.
本発明のフィルム構成としては、例えば、ポリアミドとしてナイロン（Ｎｙ）、エチレン−ビニルアルコール共重合体（ＥＶＯＨ）を使用し、Ｎｙ／ＥＶＯＨ／易剥離層／ガス透過性シール層、ＥＶＯＨ／Ｎｙ／易剥離層／ガス透過性シール層、ＰＥ／Ｎｙ／ＥＶＯＨ／易剥離層／ガス透過性シール層、Ｎｙ／ＥＶＯＨ／Ｎｙ／易剥離層／ガス透過性シール層、ＰＥ／ＥＶＯＨ／易剥離層／ガス透過性シール層、などのような多層構成が考えられるが、ガスバリア層と易剥離層、およびガス透過性シール層の組み合わせを限定するものではないし、必要に応じて新たな層を追加することもできる。 As the film configuration of the present invention, for example, nylon (Ny), ethylene-vinyl alcohol copolymer (EVOH) is used as polyamide, Ny / EVOH / easy release layer / gas permeable sealing layer, EVOH / Ny / easy. Peel layer / gas permeable seal layer, PE / Ny / EVOH / easy peel layer / gas permeable seal layer, Ny / EVOH / Ny / easy peel layer / gas permeable seal layer, PE / EVOH / easy peel layer / gas A multilayer structure such as a permeable seal layer is conceivable, but the combination of the gas barrier layer, the easy-release layer, and the gas permeable seal layer is not limited, and a new layer may be added as necessary. it can.
本発明のフィルムにおけるガスバリア層と易剥離層との剥離強度は、通常５〜１５０ｇ／２５ｍｍ幅、好ましくは５〜５０ｇ／２５ｍｍ幅、より好ましくは１０〜４０ｇ／２５ｍｍ幅である。５ｇ／２５ｍｍ幅より弱い剥離強度では、実際の商品使用開始における開封よりも前に剥がれてしまう可能性があり、１５０ｇ／２５ｍｍ幅より強い剥離強度では前述のガス透過性シール層が破断してしまう恐れがある。 The peel strength between the gas barrier layer and the easy peel layer in the film of the present invention is usually 5 to 150 g / 25 mm width, preferably 5 to 50 g / 25 mm width, more preferably 10 to 40 g / 25 mm width. If the peel strength is weaker than 5 g / 25 mm width, it may be peeled off before opening at the start of actual product use. If the peel strength is greater than 150 g / 25 mm width, the gas-permeable sealing layer will break. There is a fear.
本発明のフィルムにおいて開封による残る膜厚は、易剥離層とガス透過性シール層の厚みであるが、商品の使用中に破断してしまうような薄い厚みでなく、ないしは内容薬液成分の蒸散が効果的、かつ効率的である限り、これを限定することはない。コストおよび強度的観点で通常３０μｍ〜１００μである。 The film thickness remaining after opening in the film of the present invention is the thickness of the easy-peeling layer and the gas-permeable sealing layer, but it is not a thin thickness that breaks during use of the product, or the transpiration of the content chemical component This is not limited as long as it is effective and efficient. From the viewpoint of cost and strength, it is usually 30 μm to 100 μm.
また、製膜時、ラミネート加工時、容器製造時に熱安定性、スベリ性、濡れ性などが必要な場合、適宜酸化防止剤、スリップ剤、アンチブロッキング剤、などの添加、ラミネート面へのコロナ処理などが実施できる。 In addition, when thermal stability, slipperiness, wettability, etc. are required during film formation, laminating, and container production, addition of antioxidants, slip agents, antiblocking agents, etc., corona treatment on the laminate surface as appropriate Etc. can be implemented.
