Why can’t the vacuum effect be maintained after using the vacuum sealer? The following are possible reasons. Users can check by themselves first.   1. The wrong material of packing bags: the material of plastic bags is PE, PP which can’t maintain the vacuum effect. The air will enter into the bags after the vacuum sealer finishing working. It is recommended to choose Nylon bags, Aluminum foil bags which can maintain the vacuum effect for a long time.   2. The sealing line is not sealed well: please check whether the sealing line is complete or not. If the sealing line is not closed, the air will run into the bags. (1) If the bag is too thick, and the vacuum sealer wasn't set for enough sealing time, the heat wasn't enough to seal the bag. If the vacuum sealer can adjust the sealing time, users can add more seconds to test whether the sealing is firm. If the vacuum sealer can't adjust the sealing time, users may need to replace the thinner bag or buy another vacuum sealer with setting sealing time function.     (2) There have also been cases where the bottom seal of the original bag was not sealed properly. In this case, seal the bottom sealing line again before vacuuming.   3.     Vacuum bag styles are not suitable for vacuum sealers: non-nozzle vacuum sealers can't be used for vacuum flat bags. Therefore, if you buy a non-nozzle vacuum sealer, you must pay attention to the style of the bag you use. This vacuum sealer is a must-to-use vacuum embossed bag or Nylon gusset vacuum bag. It is recommended that when purchasing a vacuum sealing machine or vacuum bag, it is more appropriate to confirm with the supplier first.     4.     The vacuum bag is broken: (1) If the package article has acute angles, be careful not to cut the vacuum bag when putting it into the vacuum bag. (2) Vacuum sealer in the process of pumping, when the bag is shrunk to the package, it may be punctured by the packaging.

What is a Vacuum Sealer?   A vacuum sealer is a device that vacuum seals by removing air from the packaging bag, primarily used for packaging food, pharmaceuticals, chemicals, and electronic products to extend their shelf life and maintain their freshness and quality. Vacuum sealers create an oxygen-free packaging environment, effectively slowing down the oxidation, mold growth, or bacterial proliferation of products.   During the vacuum sealing process, the vacuum sealer first places the product into a specially made vacuum bag, then the machine removes the air from the bag, and finally, it heat-seals the bag opening to ensure that no air can re-enter. This method of vacuum-sealed packaging not only extends the shelf life of food but is also suitable for non-food products that need to be stored in a sterile or specific gas environment.   Features of Vacuum Sealing: - Extended Shelf Life: By creating a vacuum oxygen-free environment, vacuum sealers help extend the product's shelf life. - Maintains Freshness and Quality: Beyond extending shelf life, vacuum packaging also maintains the freshness and taste of food. - Multifunctional Application: Suitable not only for food but also for pharmaceuticals, chemicals, and electronic products that need to be stored in a sterile or specific gas environment. - Easy to Operate: Modern vacuum sealers are designed with user-friendliness in mind, offering simple and convenient operation. What is a Vacuum Sealer?  

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
