塑料中空产品内外涂层技术主要为了提高聚酯瓶的阻隔性,大大延长聚酯瓶中的啤酒及饮料的货架期,从而使其可以替代玻璃瓶。高阻隔性包装瓶技术相对来说是一种难度较大的技术,本文仅就这两种涂层技术的原理及其工业化应用做了一些入门的介绍。 Plastic hollow products inside and outside the coating technology mainly in order to improve the barrier properties of polyester bottles, polyester bottles greatly extend the shelf life of beer and beverages, making it an alternative to glass bottles. High barrier packaging technology is relatively difficult bottle of technology, this article only on the principles of these two coating technology and its industrial application to do some introductory introduction.
