作者:admin 日期:2012-10-23
绿色食品标准对纸类包装有何要求？纸类是常见的包装材料。造纸的原料主要是各种纸浆、如木浆、棉浆和草浆等，加入化学辅助原料，如硫酸铝、纯碱、亚硫酸钠等。纯净的纸是无毒的，但食品包装用纸安全性可能存在以下影响因素：纸的原料有污染物，影响接触的食品；经荧光增白剂处理的包装纸中有荧光化学物质；包装纸涂蜡层中具有多环芳烃；纸面印刷油墨和颜料中含有各种有机物；纸面长霉，污染接触食品等。

绿色食品对纸类包装基本要求是：包装可重复使用、回收利用或可降解；纸表面不允许涂蜡、上油；不允许涂塑料等防潮材料；纸箱连接应采取粘合方式，不允许扁丝钉钉合；纸箱上所做标记必须是水溶性油墨，不允许用油溶性油墨，以保证食品安全并减少环境负担。
