刚才符合的师傅反馈，为什么水煮的产品比蒸煮的产品更容易出现符合食品包装袋破包脱层的问题，今天我们来一起探讨一下。

　　The feedback from the master who just met the requirements is why products boiled in water are more prone to food packaging bag breakage and delamination than those steamed. Today, let's explore together.

　　水煮的难点呢，不在于温度，而是在于我们包装材料，它是需要长时间的，在水域环境下要抵抗水的渗透和破坏，那么水分极易侵入到我们复合薄膜的层间。腹肌最薄弱的环节就是胶粘剂和油墨，一旦它们耐水解力不足，就会发生降解，极易出现脱层和破损的情况，尤其是这种含铝膜或者是肚里的产品。

　　The difficulty of boiling water lies not in the temperature, but in our packaging materials. It requires a long time to resist water infiltration and damage in aquatic environments, making it easy for moisture to penetrate into the interlayer of our composite film. The weakest link of abdominal muscles is the adhesive and ink. Once their hydrolysis resistance is insufficient, they will degrade, making them prone to delamination and damage, especially for products containing aluminum film or in the stomach.

　　那么透明材料里面的话的这种镀层的氧化铝或者是涂层的高阻隔的材料都容易出现这种情况，我们想避免这个问题很简单，我们注意这五点。第一点的话就是我们所选择的胶粘剂一定要选择耐水解的胶粘剂，第二就是选择耐水解的油墨，必要的时候我们可以添加中水塑化剂来增加它的胶联密度。

　　So in transparent materials, aluminum oxide coating or high barrier coating materials are prone to this situation. We want to avoid this problem very simply by paying attention to these five points. The first point is that we must choose adhesives that are resistant to hydrolysis. The second is to choose inks that are resistant to hydrolysis. If necessary, we can add water-based plasticizers to increase their bonding density.

　　抗水解的能力。那么普通的油墨，它在水煮的条件下比较容易被破坏，导致符合层间它剥离。第三点就是我们符合工艺方面的一个管控，我们要确保就要充分的干燥和完全固化。如果胶层内它有溶解残留或者是固化不彻底，在水煮环境下，它会加速水解的反应。

　　The ability to resist hydrolysis. So ordinary ink is more easily damaged under boiling conditions, causing it to peel off between layers. The third point is that we have a process control in place, which requires sufficient drying and complete solidification. If there is residual dissolution or incomplete curing inside the adhesive layer, it will accelerate the hydrolysis reaction in a water boiling environment.

　　就会导致脱层的问题，所以我们要严格控制干燥温度和排风，保证足够的熟化的时间。第四点就是我们水煮的产品，它是在常压的环境下，带内的蒸汽膨胀，极易鼓包和漏裂，所以需要我们在织带的过程中加宽封边，选择高韧性的基材。

　　This can lead to delamination issues, so we need to strictly control the drying temperature and exhaust to ensure sufficient curing time. The fourth point is the product we boil in water, which expands with steam under normal pressure and is prone to bulging and cracking. Therefore, we need to widen the edge sealing during the weaving process and choose a high toughness substrate.

　　像选择尼龙和增韧的 pe，就是有这个原因。再有就是我们在阻隔层选择上，如果说选择的镀层或者是涂层的阻隔材料，我们一定建议选择高品质的油底涂胶的这类的产品，那么它的胶水和油墨以及层经的附着牢固性就比较好。

　　Choosing nylon and toughened PE is for this reason. Another thing is that when it comes to the selection of barrier layers, if we choose a coating or barrier material for a coating, we definitely recommend choosing high-quality products such as oil-based adhesives, which have better adhesion to the adhesive, ink, and layer.

　　尤其是水煮灭菌的时间过长，它袋子渗透。最后我们提到了食品厂，它用水煮方式的灭菌，那如果说遇到阻隔性材料不好的复合带的话呢，那么内容物很容易氧化变颜色，所以我们建议使用阻隔性能比较高的高阻隔的涂层材料，它可以确保在高湿环境下阻隔性能稳定，容易衰减。

　　Especially if the sterilization time for boiling is too long, the bag will seep through. Finally, we mentioned the food factory, which uses water boiling for sterilization. If it encounters composite tapes with poor barrier materials, the contents are easily oxidized and discolored. Therefore, we recommend using high barrier coating materials with relatively high barrier properties, which can ensure stable barrier properties in high humidity environments and are prone to decay.

　　可以保持内容物的色泽，口感和香味可以提高我们食品的保质期，那么关于水煮的产品容易出现符合脱层的问题，您还有想补充的地方吗？欢迎评论区留言，我们互动一下！

　　Maintaining the color, taste, and aroma of the contents can extend the shelf life of our food. However, do you have anything else to add regarding the issue of delamination in products boiled in water? Welcome to leave a comment in the comment section, let's interact!
