判定啤酒瓶帽标使用的贴标粘合剂是否会导致货架期内皇冠盖锈蚀的方法
摘要：
本发明公开了一种判定啤酒瓶帽标使用的贴标粘合剂是否会导致货架期内皇冠盖锈蚀的方法，该方法是将贴标粘合剂涂布于皇冠盖的内、外表面上，然后将涂布有贴标粘合剂的皇冠盖置于温度为20-35℃、相对湿度为70-90％的条件下放置20-30h，取出，当皇冠盖上未出现锈点和/或锈斑时，即判定使用的贴标粘合剂不会导致货架期内皇冠盖锈蚀。采用本发明所述方法可在较短时间内判定贴标粘合剂是否会导致货架期内皇冠盖产生锈蚀现象，从而避免啤酒销售过程中因皇冠盖锈蚀而产生的对啤酒产品质量及生产企业形象的影响。
摘要（英）：

The invention discloses a method for judging whether labeling adhesive used by a beer bottle cap mark can result in rustiness of a metal crown lid in a storage period. The method comprises the following steps: coating the inner surface and the outer surface of the metal crown lid with the labeling adhesive, then placing the metal crown lid coated with the labeling adhesive under the conditions that temperature is at 20-35 DEG C and relative humidity is 70-90% for 20-30 hours, taking out, and when a rust spot does not appear on the metal crown lid, judging the used labeling adhesive not to be capable of resulting in the rustiness of the metal crown lid in the storage period. By adopting the method disclosed by the invention, whether the labeling adhesive can result in the rustiness of the metal crown lid in the storage period can be judged in a shorter time, so that influence of the rustiness of the metal crown lid on quality of a beer product and production enterprise image in a beer sales process is avoided.
