一、概述在美国,一种新型喷涂涂层技术开始得到应用,第一台样机已制造,安装完毕。经过该装置加工的塑料容器有较高的阻隔性能与较好的经济性。试验表明,0.5升PET瓶使用这种叫Barrier Gard Impact的喷涂设备进行PVDC涂层后,使得瓶中内容物的货架寿命达26个星期,而未涂层瓶中的内装物的货架寿命只有8～10个星期。与复合材料瓶 I. Overview In the United States, a new spray coating technology began to be applied, the first prototype has been manufactured, the installation is completed. The plastic container processed by the device has higher barrier property and better economy. Experiments have shown that a 0.5-liter PET bottle using this Barrier Gard Impact coating equipment for PVDC coating results in a shelf life of 26 weeks for the contents of the bottle and a shelf life of only 8 for the contents of the uncoated bottle ~ 10 weeks.
