Q&A How to make the sealing line of the impulse sealer even and beautiful?   Q: Users often want to know why the sealing line is crooked and thin, rather than the flat and complete 2mm or 5mm wide sealing line tested by the manufacturer. A: The key point is cooling time. For impulse sealers, whether hand type or foot-operated type, both the sealing and cooling time are manually controlled. In order to shorten the package time, many users will ignore the cooling time directly. As soon as the heating time is up and the heating light goes off, they release the handle or foot pedal. This will result in uneven sealing lines.   Q: How long does the cooling time need to be? A: It is recommended to refer to the sealing time. If the heating time is longer, the cooling time should be increased accordingly, but not necessarily in a proportional manner. It still needs to be tested. Based on the experience, if using regular bags and the sealing time is not set for a long time, it is recommended that customers press for an additional 1 second after the heating light goes off (the editor usually counts to 3 in their mind) before releasing the handle or foot pedal.   Q: If I don't care about the appearance of the sealing line, can I ignore the cooling time? A: It is still recommended to have some cooling time. A complete sealing line is not only visually appealing to customers, but the most important, it ensures the bag is securely sealed. The impulse sealer uses heat to stick the bag mouth and seal it tightly, and then cools the sealing line by pressing the bag. This is how the sealing line can be both firm and smooth. Without cooling time to cool the sealing line, the sealing line of the bag mouth may be thin and easily melt and break, which could lead to bag rupture and increase the workload instead.
