纵封 (LS) 检查铝箔上没有起泡. 沿着包材的内边切开纵封贴条的纵封中间位置. 沿着包材的外面撕下重叠的那层包材. 纵封 (LS) 纵封 (LS) 检查纵封贴条50-60%在包上封条粘贴(SA)一侧, 40-50%应在纵封 (LS）这一侧. 在纵封条拼接后, 检查两个包. 如果需要, 利用封条滚轮上的螺丝，来调节纵封贴条的位置. 60% 40% * 渗透液配制方法 * 渗透液配制方法 * 渗透液配制方法 * 渗透液配制方法 * 纵封注射实验 * 纵封注射实验 7.5mm SA LS 气隙 * 纵封注射实验 好的 好的 * 纵封注射实验 不良封合 * 纵封褶皱 * 纵封烫伤 * 纵封鱼骨纹 检查封条的密封可以以90°慢慢地将密封条朝外拉开大约20毫米 在折痕线上时，要撕得非常慢, 再拿住并拉另外的20毫米 沿着整个边缘 两侧都要拉注意! 如果任何一层脱开, 切开密封条并从新开始拉. 纵封撕开 红墨水检测漏包 平均剪开 清洗并擦干 倒入渗透液体 20分钟后，吸干渗透液 用纸擦干 沿纵封撕开 红墨水检测漏包 * * K-Crack * * * TBA Packaging Material Depending on the product, different packaging materials will be used. A wide range of different materials are available. However, the general groups are the following. TBA/m for unflavoured milk TBA/j for fruit juices and flavoured milk TBA/k for water, tomato products etc. /ak for water /tk for tomator products TBA/w for wine etc. .

TM-00035:15 Principle of ridge inductor sealing The pre- conditions to be able to achieve a good traversal seal is that the filler settings is according to recommendations in the MM-book and also that daily and weekly maintenance and care is done accordingly to the OM-book. The actual sealing procedure; 1. The jaws hits the package material tube and a hydraulic pressure is applied. 2. When the full hydraulic pressure is applied is the IH-pulse for some hundred milliseconds introduced. The high frequency makes that the electrons in the AL-foil starts to move and by that heats up the inner PE-layer so it melts together. 3. The hydraulic maintain during the cooling phase. For cooling utilises the ridge inductors, there the
