How to solve the uneven sealing of bread bags? The seal is generally uneven and deformed. Below, we briefly analyze the reasons and solutions.
Why does this phenomenon occur during the sealing process of the packaging bag? It basically consists of the following reasons:
1. During the compounding process of the plastic bag, the compound coil is heated unevenly or the bonding is uneven.
2. After the composite coil is placed in the curing room, it is not placed correctly, resulting in uneven hands of the coil, and the fixed speed varies greatly.
3. During the curing process of the composite coil, the back groove is too deep, the ejection method is incorrect, and the demolding slope is incorrect, etc., which may cause the plastic parts to be distorted. Cooldown time is not sufficient.
