Abstract
【解決手段】酸素の作用からは保護されつつ、反面湿分の放出は確保されねばならない食品および飼料の包装用として、少なくとも1遮断層と1シーリング層を持つ多層箔を提案する。該遮断層は、気体、特に酸素に対する高い断絶機能と良好な水蒸気透過性で優れている。該シーリング層は、良好なシーリング特性および高い水蒸気透過性を保証する。
【選択図】図1
Description
本発明によれば、包装材の内部に保護用の気体を保持して食品を酸素から護りながら、他方湿分の放出も可能にする、食品および飼料の包装用の箔を提供することができる。この箔は、高い気体断絶機能と良好な水蒸気透過性を併せ持つ遮断層を有する。それにより当遮断層は、包装された食品から酸素を遠ざけて黴の繁殖を妨げつつ、他方必要に応じて包装材内部に注入される保護用気体を包装材内部に保持し、同時に食品の湿分放出、つまり包装材中での食品の乾燥を可能にするという要求をかなえている。当箔は、包装材として適した圧着パック可能な箔にするため、良好なシーリング特性を持つ表面シーリング層が追加構成されている。しかも、そのシーリング層は遮断層の機能性に影響を及ぼさないのでそれを損うということもない。すなわち、シーリング層も同等の高い水蒸気透過性を有する。気体の遮断は遮断層によって実現されるので、シーリング層は気体透過性にすることもできる。なお、「気体断絶性」および「気体透過性」はそれぞれ、周辺常温時に気状である物質、特に酸素、窒素および二酸化炭素に対する遮断性および透過性を意味している。
ポリアミド鋳造膜、ポリアミド圧延膜、鋳造または圧延成形によって製造されたポリアミド/EVOH/ポリアミド多層膜、ニス引きセロファン、PVOH含有担体膜のグループから選択するのが好ましい。
PLA膜、PLAコーティング膜、ニス引きセロファンのグループから選択するのが好ましい。
好ましい実施形態の1つでは、2つのポリアミド層とその間に配置された1つのEVOH層からなる3層形式の遮断層が共同押出し加工され長手方向に延伸加工される。遮断層の厚さは15μ〜25μである。遮断層にはPLAシーリング層が接着により貼り合わされる。PLA層の厚さは20μ〜30μである。
図1は多層箔10の構造を示している。当箔は、高い気体遮断性と良好な水蒸気透過性を示す遮断層12を有する。遮断層12は、2つのポリアミド層15とその間に配置された1つのEVOH層16からなる3層形式で共同押出し加工されている。遮断層12には接着剤ポリ乳酸塩が貼り合わされている。ポリ乳酸塩層18は良好なシーリング特性と高い水蒸気透過性を有する。
