図1は本発明の一実施形態によるフィルムロール梱包体の断面を模式的に示した図である。
本発明のフィルムロール梱包体は、かかる図1に示されるように、封止用フィルム1が巻芯2に巻き付けられたフィルムロール10が、吸湿性フィルム11で覆われた状態で、防湿性の包材12内に収容されていることが主たる特徴である。
フィルムロール10は巻芯2および該巻芯2に巻き付けられた封止用フィルム1を含む。
巻芯2は、封止用フィルム1が巻き付けられるコアとなり、巻き付けられる封止用フィルム1のシワの発生を防止する機能等を有する。
封止用フィルムは、支持体と、支持体上に設けられた吸湿性フィラー含有樹脂組成物層とを有するフィルムである。封止用フィルムとしては、吸湿性フィラー含有樹脂組成物層の支持体側とは反対側に、保護フィルムが設けられているものが好ましい。
封止用フィルムの防湿性を向上させる目的で、或いは、支持体を封止構造の一部として利用する場合、支持体としては、バリア層を有する支持体を使用するのが好ましい。バリア層を有する支持体としては、例えば、バリア層として、酸化ケイ素(シリカ)、窒化ケイ素、SiCN、アモルファスシリコン等の無機物の蒸着膜が表面に形成されたプラスチックフィルム;バリア層として、ステンレス箔、アルミ箔の金属箔等が表面に接着したプラスチックフィルム等が挙げられる。プラスチックフィルムとしては、例えば、ポリオレフィン(例えば、ポリエチレン、ポリプロピレン、ポリ塩化ビニル等)、ポリエステル(例えば、ポリエチレンテレフタレート(以下「PET」と略称することがある。)、ポリエチレン-2,6-ナフタレート(以下「PEN」と略称することがある。)等)、ポリカーボネート、ポリイミド等のプラスチックフィルムが好適であり、PETフィルムが特に好ましい。バリア層およびプラスチックフィルムは各々2層以上の複層構造を有していてもよい。市販されているバリア層を有するプラスチックフィルムの例としては、テックバリアHX、AX、LX、Lシリーズ(三菱樹脂社製)、X-BARRIER(三菱樹脂社製)等が挙げられる(これらは、酸化ケイ素(シリカ)蒸着膜が表面に形成されたPETフィルムである)。また、東海東洋アルミ販売社製「PETツキAL1N30」、「アルペット1N30」、福田金属社製「PETツキAL3025」、「アルペット3025」等が挙げられる(これらは、アルミ箔が表面に接着したPETフィルムである)。
保護フィルムは、封止用フィルムを実際に封止構造の形成に使用する前まで、吸湿性フィラー含有樹脂組成物層表面へのゴミ等の付着やキズを防止するためのものであり、保護フィルムとしては、上記の支持体で例示したプラスチックフィルムを用いることができる。好ましくは、PETフィルム、PENフィルムまたはCOP(シクロオレフィンポリマー)フィルムであり、より好ましくはPETフィルムである。保護フィルムは予めマット処理、コロナ処理の他、離型処理を施してあってもよい。離型処理に使用される離型剤としては、具体的には、フッ素系離型剤、シリコーン系離型剤、アルキッド樹脂系離型剤等が挙げられる。保護フィルムは2層以上の複層構造であってもよい。保護フィルムの厚さも特に制限されないが、1~40μmが好ましく、10~30μmがより好ましい。
酸無水物基を有するオレフィン系樹脂は、例えば、酸無水物基を有する不飽和化合物で、ポリオレフィン系樹脂をラジカル反応条件下にて、グラフト変性することで得られる。また、酸無水物基を有する不飽和化合物をポリオレフィン系樹脂の構成単量体とともにラジカル共重合するようにしてもよい。同様に、エポキシ基を有するポリオレフィン系樹脂は、例えば、エポキシ基を有する不飽和化合物で、ポリオレフィン系樹脂をラジカル反応条件下にて、グラフト変性することで得られる。また、エポキシ基を有する不飽和化合物を、ポリオレフィン系樹脂の構成単量体とともにラジカル共重合するようにしてもよい。
なお樹脂組成物層は国際公開第2011/016408号に記載のもの等の樹脂組成物層が2層以上にされた複層構造であってもよい。
本発明におけるクッション材3としては、特に限定されず、セロハン、ポリエチレン、ポリプロピレン、軟質ポリ塩化ビニル、ポリエステル(例えば、PETやPEN、これらに1,4-シクロヘキサンジメタノール等を共重合させた共重合ポリエステルなど)、ポリスチレン、ポリウレタン等の樹脂を主成分とするフィルム、該樹脂を主成分とし、発泡剤を配合し発泡させた発泡フィルム、該樹脂を主成分とし、無機及び/又は有機顔料を配合し、延伸処理によりボイドを形成した多孔質フィルム等のフィルム類、合成紙類、不織布類、上質紙、アート紙、コート紙、クラフト紙、ポリエチレンラミネート紙、水溶紙、含浸紙、発泡紙等の紙類、及びこれらの積層体等が挙げられる。また、これらのフィルム類等を後述の吸湿性フィルムのプラスチック基材に積層したものを挙げることができる。
防塵用フィルム4としては、特に限定されず、非帯電または低帯電性のフィルムであればよい。例えば、ポリ塩化ビニリデン、ポリエチレン、ポリプロピレン、ポリ塩化ビニル、ポリメチルペンテン等の樹脂を主成分とするフィルムや、該樹脂を主成分とし、導電性フィラーを配合して成形されたフィルム等が使用される。導電性フィラーとしては、特に限定されず、公知の界面活性剤などの帯電防止剤;硫化亜鉛、硫化銅、硫化カドミウム、硫化ニッケル、硫化パラジウムなどの硫化物に導電性をもたせた導電性フィラー;硫酸バリウム;酸化錫・酸化亜鉛、酸化インジウム、酸化チタンなどの金属酸化物;導電性カーボンフィラー;ケイ素有機化合物;表面金属メッキフィラーなどが適用できる。
本発明において、吸湿性フィルム11としては、25℃、相対湿度60%RHの環境下、1週間放置した前後の重量変化による吸湿量が1g/m2以上のフィルムであれば特に制限なく使用することができる。フィルムの吸湿量は3g/m2以上がより好ましく、5g/m2以上が特に好ましい。吸湿量が1g/m2未満であると、封止用フィルム1の吸湿性フィラー含有樹脂組成物層中への水分侵入を十分に抑制できない恐れがある。また、吸湿量は15g/m2以下が好ましく、10g/m2以下がより好ましい。吸湿量が15g/m2を超えると、吸湿性フィルムの変形が大きくなり、取り扱いに支障をきたす傾向となる。
本発明において、防湿性の包材には、ガス(水蒸気)の透過を防止する機能を有するガスバリア性フィルムで作成された袋体や箱体が含まれる。
フィルムロールを包装する方法としては、特に制限されず、公知の方法が用いられうる。例えば、フィルムロールを吸湿性フィルムで覆った後、吸湿性フィルムで覆われたフィルムロールを防湿性の包材内に入れて、該包材を密封する。包材の密封は、包装材の一部(開口部)を加熱し、圧力を印加した後、冷却して、密封する方法(ヒートシールによる包装方法)が挙げられる。
シリコーン系離型剤で離型処理された離型PETフィルムASST2.25(厚さ:100μm、藤森工業株式会社製)上に、下記条件で得られたワニスをダイコーターにて均一に塗布し、130℃で60分間加熱することにより、厚さ30μmの樹脂組成物層を形成した。この樹脂組成物層上にシリコーン系離型剤で離型処理された離型PETフィルム025E-0010BD(厚さ:25μm、藤森工業株式会社製)をラミネートして有機EL封止用フィルムを作製し、直径3インチ(7.62cm)のプラスチックコア芯に対し、有機EL封止用フィルムを10m巻きとった。次に、高発泡ポリエチレンシート(酒井化学工業株式会社製、「ミナフォーム」(厚さ:2mm))を巻き付け、ポリ塩化ビニリデンフィルム(旭化成株式会社、「サランラップ」(厚さ:11μm))をさらに巻き付けた後、得られたフィルムロールの周囲を、吸湿シートドライキープフィルムSPES48-231J(積層構成:ポリエチレン/吸湿層/ポリエチレン、厚さ:60μm、吸湿量:6g/m2、佐々木化学薬品株式会社製)で覆った。これを、ポリエチレン基材にアルミニウム箔が接着された包材からなるアルミ袋MBY-92100(水蒸気透過率:0.5g/m2/day、エーディーワイ株式会社製)に入れた後、袋の入れ口をヒートシールにて閉じて、包装体(梱包体)を得た。
シクロヘキサン環含有飽和炭化水素樹脂(アルコンP125、60%スワゾール溶液、荒川化学社製)に、無水マレイン酸変性液状ポリイソブチレン(HV-300M、東邦化学工業社製)、ポリブテン(HV-1900、JX日鉱日石エネルギー社製)、および焼成ハイドロタルサイト(KW2200、協和化学工業社製)を3本ロールで分散させて、混合物を得た。得られた混合物に、エチレン-グリシジルメタクリレート共重合体(BONDFAST BF-7M、住友化学株式会社製)、アニオン重合型硬化剤(2,4,6-トリス(ジアミノメチル)フェノール)およびトルエンを配合し、得られた混合物を高速回転ミキサーで均一に分散して、樹脂組成物のワニスを得た。
実施例1と同様にして封止用フィルムを作製し、直径3インチ(7.62cm)のプラスチックコア芯に対し、有機EL封止用フィルムを10m巻きとった。次に、コア芯内部にシリカゲルMP20G(豊田化工株式会社製)を2つ固定し、高発泡ポリエチレンシート(酒井化学工業株式会社製、「ミナフォーム」(厚さ:2mm))を巻き付け、ポリ塩化ビニリデンフィルム(旭化成株式会社、「サランラップ」(厚さ:11μm))をさらに巻き付けた後、これをアルミ袋MBY-92100(エーディーワイ株式会社製)に入れ、袋の入れ口をヒートシールにて閉じ、包装体(梱包体)を得た。図2は得られたフィルムロール梱包体の模式断面図である。

実施例1、参考例1及び比較例1の梱包体をそれぞれ1週間保管したものと、1ヶ月保管したものから、有機EL封止用フィルムを取り出し、有機EL封止用フィルムから、試料(横:約100mm、縦:約100mm、重量:100~300mg)を切り出し、保護フィルムを剥離して、その樹脂組成物層の含水率を、電量滴定法のカールフィッシャー水分測定装置(三菱化学アナリテック社製「微量水分測定装置CA-200」)を用いて測定した。この装置は、加熱可能なサンプルを設置するガラス容器と、サンプルを加熱する際に気化した水分を滴定する反応液が入った滴定装置から構成された。気化した水分は、流量:250±25ml/minの窒素を流すことでガラス容器から滴定装置の反応液側に移動した。測定は、窒素雰囲気下(水蒸気量<0.1ppm)に置換したガラス容器内に、サンプルを投入し、130℃の条件下で気化した水分の量を滴定し、樹脂組成物層の含水率を算出した。結果を下記表1に示す。
