摘要
啤酒包装对于氧气和二氧化碳的阻隔性有很高的要求,目前满足啤酒包装的主要材料是玻璃瓶、金属罐。PET啤酒瓶是近期研究的热点,通过改性使PET啤酒瓶的阻隔性能有所提高,满足啤酒包装的要求。本文介绍了PET材料的阻隔性能、PET啤酒瓶阻隔性能的主要改进技术研究及应用,如通过共混改性提高PET材料阻隔性能,在PET瓶的外部或内层喷涂阻隔层,带阻隔层的多层结构PET瓶等。
Beer bottles required the excellent barrier properties to oxygen and carbon dioxide. Glass bottles, metal cans were the best select for beer packaging. Until 1990, PET beer bottle became the research focus. After modified, the barrier properties of PET bottles improved significantly and meet the requirements of beer packaging. This article described the barrier properties of PET materials, and the current research and application development of PET beer bottle barrier technology, such as blended with other materials, coated with excellent barrier materials, composited by multi-layer structure and so on.
