前言东セロ(株)开发的环境适应性强的非氯系气体阻隔性薄膜,[A-OPBH]薄膜上市已经经过了十年,在市场中得到了广泛的应用。[A-OPBH]薄膜是将氧气阻隔性优良的聚乙烯醇树脂(下称PVA)涂布到水蒸气阻隔性优良的OPP薄膜上得到的薄膜,可以防止其所包装的内容物的氧化劣化以及由于湿气导致的内容物口感的下降。以前的气体阻隔性薄膜,通常采用氯系聚合物聚偏二氯乙烯(下称PVDE)涂布的薄膜,如东セロ(株)的V-OP等,由于其燃烧时可能产生二恶英,用环境适应性好的薄膜代替它们,已为人们所接受。
INTRODUCTION The environmentally friendly nonchlorinated gas barrier film developed by Tontoc Co., Ltd. has been in use for more than 10 years in the market, and has been widely used in the market. The [A-OPBH] film is a film obtained by applying a polyvinyl alcohol resin (hereinafter referred to as “PVA”) excellent in oxygen barrier property to an OPP film excellent in water vapor barrier property and capable of preventing oxidative deterioration of the contents packaged therein and The texture of the contents due to moisture decreases. As the conventional gas barrier film, a film coated with a polyvinyl chloride-based polymer polyvinylidene chloride (hereinafter referred to as PVDE), such as V-OP from Tosoh Co., Ltd., is generally used. Since dioxins may be generated during combustion, It has been accepted by people to replace them with environmentally friendly films.
