近来,国外应用的纸基复合包装技术有了新进展。其类型有贴膜型、衬袋型、嵌入型、液体型等。由于油分子极小,在研制纸基复合包装中的主要技术难题就是解决防渗。最近,日本科研人员研制了一种盒装食油的复合纸盒,非常成功。其复合纸的结构为以纸为基材,经铝塑6层复合制成。由于?
Recently, overseas applications of paper-based composite packaging technology has made new progress. The types of foil type, lining bag type, embedded type, liquid type and so on. Due to the extremely small oil molecules, the major technical challenge in the development of paper-based composite packaging is to solve impermeability. Recently, Japanese researchers developed a box of cooking oil composite carton, very successful. The structure of the composite paper to paper as the substrate, the aluminum-plastic composite made of 6 layers. due to?
