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.

In recent years, vacuum packaging has become very popular. Vacuum packaging keeps damp proof, extended shelf life, and reduced storage space. There are various types of vacuum sealing machines available on the market. How to find a suitable vacuum sealer for your product? The following are specially divided into three categories for the vacuum sealers sold on the market (Chamber Vacuum Sealer, Non-nozzle Vacuum Sealer, and Nozzle Vacuum Sealer) to introduce advantages and disadvantages. There are other places to pay attention to when buying, hope to help everyone buy a suitable vacuum sealer, and enhance the quality of product.   ※Chamber Vacuum Sealer This is the most familiar and most commonly seen vacuum sealer. As the name suggests, it looks like a box. Therefore, large size and heavy weight are the biggest drawbacks of this vacuum sealer, but the vacuum degree is the best compared to the other two types of vacuum sealers. We also call this vacuum sealer an internal vacuum sealer. Because the items which you want to vacuum have to be put into the vacuum chamber in the vacuum sealer, and can be vacuum packaged. Since the vacuum item needs to be put into the vacuum chamber, the product will be limited by the size of the vacuum chamber. If the product is larger, the vacuum chamber must be larger. As the size of the vacuum sealer increases, its price also tends to increase. Therefore, when purchasing, it needs to consider whether the internal size of the vacuum chamber is suitable for your needs. The chamber vacuum sealer is further divided into oil-less and oil-type vacuum sealer due to the different types of vacuum pumps installed inside the machine. The vacuum capability of oil-less type vacuum sealers is slightly lower than that of oil-type vacuum sealers. Oil-less type vacuum sealer is suitable for dry products, such as tea, dried fruit, rice, and electronic parts. The price of this vacuum sealer is lower than that of the oil-type vacuum sealer, but the vacuum capability is sufficient for dry vacuum packaging. Oil-type vacuum sealer is suitable for both dry and moist products. If there is liquid in the product, it's recommended to choose an oil-type vacuum sealer. Suitable for packing products: meat, seafood, liquid, and powder. The Oil-type vacuum pumps installed in the Oil-type vacuum sealers on the market have different vacuum capabilities. If you need vacuum packaging for seafood or meat products, it's recommended to choose an Oil-type vacuum sealer with better vacuum capability. If the product itself is soft, even after being vacuumed, it will still be soft to the touch, and will not be as hard as dry products after being vacuumed. The price of Oil-type vacuum sealers is higher than that of oil-less-type vacuum sealers, and the higher the required vacuum capability, the higher the price. Also, it should be noted, Oil-type vacuum pump needs to add vacuum oil, so when using an Oil-type vacuum sealer, it's a must to regularly check the amount of vacuum oil and the clarity of the vacuum oil. If the oil level is below the standard, vacuum oil needs to be added; if the vacuum oil is cloudy, the old oil must be drained before adding new vacuum oil. The more often the vacuum sealer is used; the frequency of adding and draining oil is also higher. When the vacuum degree drops, you can first check whether it is due to the vacuum oil. Some oil-type vacuum sealers will also be equipped with oil mist catchers, to capture the oil mist generated during the operation of the oil-type vacuum pump. Smoke generation was found during the operation of the vacuum sealer, oil mist is likely generated when the oil vacuum pump is running, which is a normal phenomenon. The installation of an oil mist catcher is to reduce the situation of oil mist drifting. The oil mist catcher is a consumable, and the frequency of use will affect its life.   When purchasing a vacuum sealer, factors to consider include price, the suitable types of vacuum bags, vacuum efficiency, the size and type of products to be sealed, and the operating method. No matter what kind of product you want to vacuum, it's recommended to bring the product to the site for testing before purchasing, test the vacuum effect and understand how to operate it, this will allow you to choose the most suitable vacuum sealer for your needs.
