涂布玻璃纸
 |
涂布玻璃纸是用普通玻璃纸为基材，经过锚固处理工艺，然后在其表面上涂敷一层硝化棉涂料，赋予玻璃纸防潮性、热封性、对各种气体的阻抗性，具有优良的印刷复合功能，适合高速自动包装，可显著提高包装效率，是医药、茶叶、食品、烟草等商品的包装装璜材料。
COATED CELLOPHANE (MST)
Coated cellophane film is made by applying a thin layer of nitrocellulose laquer on the surface of pt-cellophane, which gives the film the important properties of moisture proofness and heat sealability, the barrier function to various gases, the excellent function for printing and laminating. It is suitable for automatic high-speed packing and can significantly increase packing and decorating material for medicines, foodstuff, tea, cigarettes and tobacco, etc.
