core tip: it is easy and easy to solve the problem of bubbles without solvent. Generally, if bubbles appear, first look at whether the bubbles are regular or irregular. If they are regular, consider the rubber roller. If they are irregular, consider whether the glue amount is sufficient, etc. However, there is also a special kind of bubble, which should not be ignored by the employees of the soft bag factory

it is simple and easy to solve the problem of bubbles without solvent. Generally, if bubbles appear, first look at whether the bubbles are regular or irregular. If they are regular, consider the lower rubber roller. If they are irregular, consider whether the amount of glue is sufficient, insufficient air pressure, poor glue leveling, temperature control, residual solvent of printing film, too fast speed, etc

when the above situation occurs, it should be solved according to the bubble sample, which has a significant environmental benefit of 10 points. Increase the pressure, control the glue amount and so on, so as to better recommend the speed of the model, or add a little temperature, and the bubble problem can be solved. Remember, if there are bubbles on the anti-counterfeiting label in winter or similar salt bags, the solution must be determined according to the sample

it is worth noting that there is also a special bubble in the compounding process and shutdown. When starting up, bubbles appear in the tape joint (which may not appear in some manufacturers). This happens when the bottom film is PE with a thickness of more than 5 wires

generally, large areas of bubbles are generated through the joint, and the operator cuts and ties them with a knife. This is a dangerous operation and waste in the process of operation

in fact, it is very simple to solve this problem: when stopping the machine to receive the material, stick the tape forward and backward. If there are bubbles on the front, the bag making by reverse pasting will break the material. If there are bubbles on the front and reverse pasting, it can not only solve the bubbles, but also ensure the continuous material making of the bag. The effect is better, and the compound loss and bag making loss are less. Due to the angle of the laminating roller of the laminating machine and the dream of the tail when the tape is pasted, the joint bubbles caused by the advanced laminating roller are pasted on both sides with the best effect and the least waste
