Definitions
- the present invention relates to a packaging material that requires excellent airtightness such as foods, pharmaceuticals, and electronic parts having excellent transparency, gas barrier properties, printability, and flexibility, or a transparent barrier film having excellent properties as a gas blocking material. It relates to a manufacturing method and a manufacturing apparatus.
- a plastic film obtained by laminating an inorganic substance on a plastic film is commercially available.
- metal oxides such as silicon oxide and aluminum oxide are often used from the viewpoint of transparency.
- the metal oxide is mainly laminated on a plastic film by a vapor deposition method or a CVD method.
- a laminated film having an aluminum oxide layer or a silicon oxide layer as a barrier layer prepared by a reactive vapor deposition method in which aluminum or silicon monoxide is evaporated and oxygen is introduced is the mainstream (see, for example, Patent Document 1). ..
- a plastic film in which an organic layer or the like is coated on the inorganic layer to improve the barrier property and protect the inorganic layer is also commercially available (see, for example, Patent Document 2).
- the transparent barrier film is used by printing when it is used as a packaging material, or by laminating another plastic film with an adhesive or the like.
- plastic films to be laminated but an unstretched polyethylene film or polypropylene film called a sealant is generally laminated to make a bag.
- the barrier performance of the transparent barrier film produced by the reactive vapor deposition method is affected by the film thickness and degree of oxidation of the formed inorganic layer. If the film thickness is too thin, a uniform layer cannot be formed and the barrier performance becomes insufficient, and if the film thickness is extremely thin, the barrier performance is not exhibited. Further, if it is too thick, the inorganic layer is easily cracked when the plastic film is bent, and the barrier performance cannot be maintained. As described above, the aluminum oxide layer and the silicon oxide layer have a suitable film thickness range and are values to be managed.
- the incompletely oxidized aluminum oxide layer loses its metallic luster and turns brown as oxidation progresses from metallic aluminum. It has a barrier property in the state of metallic aluminum, but loses its barrier property in a slightly oxidized state. As the oxidation progresses, the color becomes lighter, the transparency appears, and the barrier performance comes out. Further, when oxygen is blown to eliminate the coloring, the barrier performance of the aluminum oxide layer prepared by reactive vapor deposition deteriorates. Therefore, the aluminum oxide layer produced by reactive vapor deposition has a range of suitable degree of oxidation and is a value to be controlled. The same applies to silicon oxide.
- the degree of oxidation can be obtained from the abundance ratio by obtaining the valence from chemical shift using X-ray photoelectron spectroscopy (XPS), but it is very time-consuming, so light transmittance is generally used as an alternative index. is doing.
- XPS X-ray photoelectron spectroscopy
- the method of adjusting the evaporation amount while keeping the amount of oxygen introduced into the vacuum device constant will be explained.
- the oxygen introduction amount, the traveling speed of the plastic film, and the heating conditions of the vapor deposition material are variously changed to obtain the conditions of the target light transmittance and the film thickness. Since it is easy for the device to set the amount of oxygen introduced and the running speed of the plastic film to predetermined values, the required conditions are met.
- a transparent barrier film having a target film thickness can be obtained. That is, as the amount of evaporation increases, the amount of introduced oxygen per amount of evaporation decreases, so that the degree of oxidation decreases and the light absorption coefficient of aluminum oxide increases. In addition, since the traveling speed of the plastic film is constant, the film thickness to be deposited becomes thick. Therefore, since the light transmittance is lowered, it is possible to adjust the heating to be lowered to reduce the amount of evaporation. The reverse is also true. Therefore, in order to change the conditions and the manufacturing equipment, it is necessary to make a prototype to determine the conditions again.
- the induction heating method, the resistance heating method, and the electron beam heating method are mainly used as the method for heating the evaporation source.
- the induction heating method and the electron beam heating method even if the heating is performed with the same electric power, the amount of the vapor-deposited material and the state of heat insulation change and the evaporation amount changes, so that it is necessary to control the evaporation amount to be constant.
- an aluminum wire is sent to a boat-shaped heating element made of conductive ceramic called a BN composite to evaporate, so that the amount of evaporation can be estimated by increasing or decreasing the amount of aluminum liquid on the boat. That is, if the liquid is in a constant state, the amount of evaporation can be said to be equal to the amount of sending the aluminum wire, so the amount of evaporation can be estimated. Therefore, there is a manufacturing method in which the amount of oxygen introduced can be adjusted by using the measured value of the light transmittance monitor while the amount of evaporation is constant to adjust the light transmittance.
- the oxygen introduced as a premise is the aluminum oxide layer at a constant ratio. It is assumed that there is no gas that oxidizes the aluminum metal other than the introduced oxygen.
- the pressure in the chamber changes, the ratio of oxygen taken into the aluminum film and oxygen that is not taken into the aluminum and is exhausted by the pump changes. Even after the vacuum is started from the atmospheric pressure and the pressure becomes such that vapor deposition is possible, the water adsorbed on the wall of the vacuum tank gradually comes out, and the adsorbed water decreases with time, and the pressure decreases.
- oxygen must be introduced uniformly in the width direction (TD) of the plastic film. If the oxygen ejection is distributed in TD, naturally there will be a difference in the degree of oxidation in TD and a difference in the light transmittance. Since the light transmittance is adjusted to be uniform, the film thickness becomes non-uniform according to the non-uniformity of oxygen ejection.
- the amount of evaporation can be estimated to some extent by the resistance heating method, it is necessary to visually check the resistance heating boat and adjust until the evaporation stabilizes.
- a heating element made of BN composite and having a width of about 30 mm which is called a boat, is generally installed on the TD at intervals of about 100 mm for vapor deposition.

Abstract
Description
中でも、アルミニウムや一酸化珪素を蒸発させ酸素を導入する反応性蒸着法などにより作成する酸化アルミニウム層や酸化珪素層をバリア層とする積層フィルムが主流となって
いる(例えば、特許文献1参照)。
透明バリアフィルムは、包装材料に使用するときに印刷をしたり、また他のプラスチックフィルムを接着剤等を使って積層したりして使われる。積層されるプラスチックフィルムは種々あるが、袋を作るためにシーラントと呼ばれる未延伸のポリエチレンフィルムやポリプロピレンフィルムが一般には積層される。
酸化珪素も同様である。
すなわち、蒸発量が多くなると蒸発量当たりの導入酸素量が減ることになるので酸化度が低くなり酸化アルミニウムの光吸収係数が大きくなる。また、プラスチックフィルム走行速度は一定なので堆積する膜厚も厚くなる。従って光線透過率が低くなるので加熱を下げて蒸発量を下げる調整が可能となる。逆も同様である。
したがって、条件変更及び製造装置を変更するためには再度条件を決めるための試作が必要となる。
従って蒸発量が一定として、光線透過率モニターの測定値を使って酸素の導入量を調整して光線透過率を調整することができる製造方法がある。
このために蒸着初めより、蒸着終わりの方が酸素を取り込んでいる量が低くなり、光線透過率が高くなるので光線透過率で調整すると膜厚が薄くなる。
また、製造装置の壁に吸着する水分は製造装置を大気にさらしている時間、その時の大気の湿度により異なる。従って、蒸着開始時の水分吸着量を一定とすることはむつかしい。フィルム走行方向(MD)に安定したバリア性、酸化度の長尺な透明バリアフィルムを得ることは難しい。
対して、TDに連続した坩堝を使用する電子ビーム加熱方式ではTDに連続した蒸発源をうる。TDに膜厚の変動があっても連続して緩やかなので抵抗加熱方式のような濃淡は明確にみえない。
透明ガスバリアフィルムを製造する方法であって、プラスチックフィルムの少なくとも片面に金属アルミニウム又は珪素を蒸発させ酸素を吹き込むことにより生成した酸化アルミニウムを主成分とする酸化アルミニウム層又は酸化珪素を主成分とする酸化珪素層を有する透明ガスバリアフィルムを製造する工程を有し、該工程において、形成した酸化アルミニウム層又は酸化珪素層を蛍光X線を用いた膜厚計で膜厚を測定するとともに、光線透過率測定装置で酸化アルミニウム層又は酸化珪素層の光線透過率を測定して所定の値になるように制御することを特徴とする透明ガスバリアフィルムの製造方法である。

本発明の透明ガスバリアフィルムの製造方法は、プラスチックフィルムの少なくとも片面に金属アルミニウム又は珪素を蒸発させ酸素を吹き込むことにより生成した酸化アルミニウムを主成分とする酸化アルミニウム層又は酸化珪素を主成分とする酸化珪素層を有する透明ガスバリアフィルムを製造する工程を有し、該工程において、形成した酸化アルミニウム層又は酸化珪素層を蛍光X線を用いた膜厚計で膜厚を測定し、光線透過率測定装置で酸化アルミニウム層又は酸化珪素層の光線透過率を測定して、所定の値になるように制御することを特徴とする透明ガスバリアフィルムの製造方法である。
ともに、光線透過率測定装置で金属酸化物層の光線透過率を測定して所定の値になるように制御する手段を有することを特徴とする透明ガスバリアフィルムの製造装置である。
金属アルミニウム、または金属珪素等より酸化アルミニウム、酸化珪素を生成する方法としては反応性スパッタ法があるが、製造速度の観点から反応性蒸着法が好ましい。
製造効率の観点より、基材のプラスチックフィルムをロール ツウ ロールで移動しながら酸化アルミニウム層あるいは酸化珪素層を形成し、光線透過率、膜厚を測定して連続して製造するのが好ましい。
基づき電子銃(9)のビーム出力を調整して坩堝(10)からの蒸発量を調整する。膜厚を測定した透明バリアフィルムは巻き取りロール(11)に巻き取る。全てのプラスチックフィルムを蒸着したら、シャッター(12)を閉じて停止する。
TDに並べたボートの個々の蒸発速度を調整することでプラスチックフィルムに形成される酸化アルミニウムの膜厚分布を調整できる。また、アルミニウムワイヤの送り速度からおおよその蒸発速度が推定できる利点がある。
しかし、抵抗加熱ではアルミニウムワイヤーを連続的に供給するためどうしても不純物が入って蒸発速度を上げた時に突沸が起こり液体のアルミニウムが飛ばされプラスチックフィルムにダメージを与えてしまうことがある。また、TD方向に点に近い蒸発範囲の並びで蒸着するの100mm間隔の不均一さは残る。
しかし、この方式では材料は蒸着途中で供給しないので、材料が減っていき蒸発状況が変わり同じ電力で加熱しても蒸発量が変わってしまう。また、抵抗加熱方式よりは蒸発面積は広いがTDに坩堝を並べた形になるので小さな不均一性はTDに残る。
しかし、誘導加熱と同じく同じように加熱していても蒸着材料が減り加熱状況が変化するので蒸発量を一定とすることは難しい。
珪素材料を蒸発させる場合、珪素材料は金属珪素以外、昇華で蒸発していくので、金属アルミニウムのように周りから液体になったアルミニウムが加熱位置に供給されない。そこで坩堝を移動させて、材料を供給することが好ましい。
また、蒸着が終わった後に速やかに大気圧に戻すためにコーティングロールを加熱する機構を持っていることが好ましい。低温のまま大気に開放するとコーティングロールが結露してしまいプラスチックフィルムが濡れたり、次の真空引きに影響がでる。
350nmを中心とする光線透過率を測定する方法としては、350nm付近の光を出す発光体を使う方法と350nm付近の光を受光する方法はある。350nm付近の光を出す方法としては、キセノンランプなど紫外線を強く発光するランプにフィルターを使い波長を絞る方法、または、350nm付近に発光波長を持つLEDを使う方法がある。受光する方法としては光検出体の前に350nm付近のだけを透過するフィルターを設置する方法があるが、効率の観点と取り扱いのしやすさより350nm付近に発光波長を持つLEDを使った方法が好ましい。
校正板は測定対象の透明バリアフィルムが発生する蛍光X線強度に近い強度の蛍光X線を発生し、経年により劣化することがないものが好ましい。(例えばチタンなどの金属板上
に酸化アルミニウム層を積層した板)校正板は蛍光X線強度が異なる2種類持つのがさら
に好ましい。
校正板は蛍光X線膜厚計に付随させ、膜厚測定開始前にX線を照射して蛍光X線強度(I1、I2)を測定する。測定した蛍光X線強度は蛍光X線強度から膜厚に換算するための計算式を決めた時に計測した校正板の基準蛍光X線強度(I01、I02)と比較してX線強度を補正する関数を作成し膜厚測定時に観測した蛍光X線強度(I)を補正するのが好ましい。
例えば2種類の校正板があるときの補正は補正後の蛍光X線強度(I’)とすると式1で表すことができる。
I’=αI+β -(式1)
α=(I01-I02)/(I1-I2)
β=(I1I02-I2I01)/(I1-I2)
I’:補正後蛍光X線強度
I:補正前蛍光X線強度
I01:校正板1の基準蛍光X線強度
I02:校正板2の基準蛍光X線強度
I1:校正板1の測定蛍光X線強度
I2:校正板2の測定蛍光X線強度
この補正により酸化アルミニウム層または酸化珪素層のみからの蛍光X線強度が求まる。
精度の観点から検量線法で求めることが好ましい。
蛍光X線膜厚計の測定部は比較的大きいのでTDに直線上に配置させずに直線に対して千鳥状に配置してもよい。この場合、測定部の間隔とは、プラスチックフィルムがMDに移動するのにしたがい、少なくとも2台のモニターが測定しているスポット範囲の重心が描く軌跡の直線あるいは曲線の最短距離を言う。
酸化アルミニウムまたは酸化珪素は完全酸化物で無色であるが、酸素欠陥により光吸収が起きる。光吸収係数をα0とすると式2、式3で光線透過率Tlと関係付けられる。
Il=Il0×EXP(-α0・t) -(式2)
Tl=Il/Il0×100 -(式3)
Il:透明ガスガリアフィルムの透過光線量
Il0:透明ガスガリアフィルムの原反のプラスチックフィルムの光線透過量
α0:酸化アルミニウム層または酸化珪素層の吸収係数
t:酸化アルミニウム層または酸化珪素層の膜厚
Tl:酸化アルミニウム層または酸化珪素層の光線透過率
酸化アルミニウム層または酸化珪素層の酸化度は吸収係数と関係付けれる。従って酸化アルミニウムまたは酸化珪素の膜厚を明確にすることにより光線透過率を測定して光線透過率を調整することにより酸化度を制御できる。
図2で示す様に酸化アルミニウム層において酸化不足による光吸収が350nm付近で顕著になるので酸化度の調整のためには350nm付近の光線透過率を使うことが好ましい。
本発明で言う酸素ノズルはTDに酸化が均一になるように酸素が供給できる方法が好ましい。例えばTDに長いパイプを配置し適度の間隔でコンダクタンスを調整した穴、例えば適度な大きさの穴を開けたものをノズルとすることによりTDに酸素分布を調節して酸素を供給することができる。また、穴の代わり細長いスリットを設け開口幅を調整することによりTDに酸素分布を調整できる。このパイプにはマスフローコントローラーを接続してパイプに供給する酸素を調整し酸化度を調整することができる。
さらに積極的にTDの酸化度の分布を調整する方法としてはノズルをTDに並べてここにマスフローコントローラーを取り付け、ここのノズルから供給する酸素量を調整してTDに光線透過率を調整して酸化度が調整できる。
坩堝とコーティングロールとの中間位置あるいはコーティングロールの近傍に設置するのが好ましい。
酸素ノズルの噴出口に蒸発粒子が付着してガスの流れが変わる。または、噴出口がふさがり流量が変化しないように遮蔽板を設けることが好ましい。
例えば、光線透過率測定装置で光線透過率を測定した後で蛍光X線膜厚計で膜厚を測定する例で説明しているが、蛍光X線膜厚計で膜厚を測定した後に光線透過率測定装置で光線透過率を測定する光線透過率測定装置を設置するように配置もできる。また、プラズマ処理装置を省略することもできる。
