摘　　要：基于T/CWA 205—2021《建筑密封胶用包装材料》标准,介绍了密封胶用包装材料的性能要求,指出:包装材料应印刷清晰、无重影;软膜除基本力学性能外,应重点关注其水蒸气透过量、热封部位是否有虚封等项目;塑料胶瓶应重点关注瓶身与底盖的契合性、瓶嘴韧性、耐渗油性等项目;灌装密封胶后应尽量存放在温度5~27℃、湿度不高于70%的环境中。Based on standard T/CWA 205—2021“Packing materials for building sealants”,the performance requirements of packing materials for sealants are introduced in this article.It points out that packing materials should be printed clearly and have no ghosting;in addition to basic mechanical properties,water vapor permeability and whether there is virtual sealing at the heat sealing area should be focused on for soft film;for plastic bottles,the compatibility between the bottle body and the bottom cover,the toughness of the bottle mouth,and the leakage-proof performance should be focused on;after filling the sealant,it should be stored in an environment with a temperature of 5~27℃and a humidity not exceeding 70%.
