Abstract
Description
図1aは、包装材料の断面を概略的に示す。装飾層(11)は、適切なLDPEまたはPPなどのポリオレフィンである。装飾層は、例えば、他の層のいずれかに設けられる、印刷パターン、穴、および/または弱化部(図面には図示なし)のカバーを提供するのに使用されてもよい。装飾層の一方の面にはバルク層(12)が配置される。装飾層とは反対側の、バルク層の他方の面には、バリア層(14)が配置される。バリア層とバルク層との間には、必要に応じて任意の積層体層を配置することができる。同様に、一方または両方の層は、バルク層とバリア層との間に十分な接着をもたらすために、表面改質するかまたはコーティングを含んでもよい。バリア層(14)は、パックされる製品によって決まる特定の要求に応じて、酸素、光、水、および水蒸気バリアなどの所望のバリアを提供する。バリア層は、例えば、アルミニウム箔、またはPECVD被覆フィルムなど、金属化または蒸着コーティングされたものなどの蒸着フィルムであることができる。バルク層とは反対側の面では、バリア層に、PEもしくはPPまたはそれらのブレンドなど、適切なポリオレフィンなどのヒートシール可能な層(16)が配置される。バリア層とヒートシール可能な層との間には、必要であれば接着剤が使用されてもよい。ヒートシール可能な層は、完成しパックされた包装容器内の製品に面する層である。
本明細書で詳細に考察し例証する積層包装材料に関連する態様が、以下に記載される。いくつかの態様は、包装材料を準備する方法に関連する。それに加えて、一部の態様は、液状および半液状食料製品に適した包装容器の提供における、包装材料の使用に関連する。包装材料は、1つの態様では、例えば、無菌包装容器を製造する、テトラパック(登録商標)A3充填機などの製袋充填タイプの、液状または半液状食料製品のための充填機で使用される。いくつかの態様では、包装容器は包装材料のロール供給ウェブから製造される。いくつかの態様では、包装容器は包装材料の半加工品から製造される。
CSF(カナダ標準ろ水度)値530mlの約75重量%のトウヒCTMP繊維からの水性セルロースパルプを、約25重量%の漂白軟材化学パルプとブレンドして、濃度を約3〜4%とした。約2重量%のドデシル硫酸ナトリウムSDSを水に混合することによって、発泡流体を準備した。撹拌と同時に加圧水を添加した後、適切な発泡体が作られるまで、連続撹拌および混合の下で繊維分散物を発泡体に添加した。このように得られた繊維性発泡体を、ノズル(ヘッドボックス)に通し、コーティング状にして多孔質フェルトの移動ウェブ上に置いて水抜きし、その後、このようにしてウェブ状に形作られた発泡体シートを乾燥させた。
