Professional 30cm Foot type constant heat sealer Manufacturer

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.

How a Vacuum Sealer Works   Many friends often ask: "Do I have to use a vacuum bag when using a vacuum sealer?" "Do I have to use special bags when using a vacuum sealer? Can I use flat vacuum bags with non-nozzle type vacuum sealers? Can I use all type vacuum bags with chamber vacuum sealers?" You can find the answer after reading the following instructions.    1. Do we have to use vacuum bags for vacuuming? A: If you only want to remove air, any material can be used. But if you want to maintain the vacuum state for a long time, you must use vacuum bags which are PA (Nylon) material or aluminum foil bags with high airtightness.   2.Does "vacuum" really mean making the bag completely free of gas inside? A: Actually not, the main principle is to reduce the air inside the bag to a level where microorganisms cannot survive, reducing oxidation or product spoilage, keeping items less susceptible to rusting, and maintaining the freshness and shelf life of food inside the bag.   3.Differences in principles between Non-nozzle vacuum sealer and chamber vacuum sealer. A: There are two different principles of air extraction, which also lead to different advantages and disadvantages. (1) Non-nozzle vacuum sealer: Directly extract the air from the bag, and then use heating to melt and seal the plastic bag. Therefore, if you want to package fluids or powders, Non-nozzle vacuum sealers are likely to extract the contents you want to package, or extract contents that should contain moisture. Sometimes it may even cause internal parts to get wet and be damaged.   Most of the vacuum bags seen on the market have patterns on them, which is because most vacuum sealing machines are direct air suction type. When sealing wet items with this type of vacuum packaging machine, it is necessary to form channels for smooth air. These channels are the patterns or folds on the vacuum bags or aluminum foil bags commonly seen in the market. When the air in the bag is reduced, aerobic bacteria cannot survive, so the items can be preserved for a longer period of time. Therefore, whether it is a grid pattern, diamond pattern, or the vacuum channel sealer bags made by our company, they are all designed to facilitate air flow. Therefore, we would recommend using non-nozzle vacuum sealers for items with less water content and larger particles inside.   (2) Chamber vacuum sealer: When the lid is closed, the motor begins to perform the vacuuming action. At this time, the air inside the vacuum chamber and inside the vacuum bag will be affected by the motor and flow, so the pressure inside the vacuum chamber will gradually become negative pressure. At this time, we may observe a phenomenon where the vacuum bag we placed inside is expanded. This is because the speed at which the air is removed from the vacuum bag cannot be as fast as that in the vacuum chamber, which causes the pressure inside the bag to be greater than other parts of the vacuum chamber in a short time. This phenomenon will also cause the air inside the bag to accelerate and leave the bag at the moment the solenoid valve operates, and at the same time, the heating plate will heat and seal the bag.   Since it does not directly vacuum the air out of the bag, there is no need to worry about the moisture inside the bag being drawn out. For items with liquid or powder content, we would recommend using a chamber vacuum sealer. Because the air inside the vacuum chamber is vacuumed out, the bag does not need an additional air extraction duct, so it can be used without embossed vacuum bags. 表單的頂端   表單的底部表單的頂端
