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.

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.   ※Non-nozzle Vacuum Sealer         A non-nozzle vacuum sealer is a new type of vacuum sealer that has appeared in recent years, in terms of price, it's cheaper than the Chamber vacuum sealer, although the vacuum degree is lower than that of the Chamber vacuum sealer, for many products it is sufficient. This Non-nozzle vacuum sealer is equipped with an oil-less pump, so if the product itself has a lot of water (such as soup) or powder, a Non-nozzle vacuum sealer is not recommended, because moisture or powder will be drawn into the machine with the operation of the vacuum pump, easily cause damage to internal parts.         Non-nozzle vacuum sealer belongs to the external vacuum sealer, different from an internal vacuum sealers, the product is vacuumed outside the machine. Therefore, the product is not limited by the size of the vacuum chamber, unlike the chamber vacuum sealer, as long as the width of vacuum bags is smaller than the size of the sealing line of the external vacuum sealer, unlimited length, but if the vacuum bag is too long, it is recommended to find an external vacuum sealer with strong vacuum capability.         This type of vacuum sealer on the market has a plastic casing and a stainless steel casing. Non-nozzle vacuum sealer with plastic housing is small in size, and cheap in price, but if it's vacuum packaged for a long time, high frequency of operation, it's not recommended by a Non-nozzle vacuum sealer with a plastic case, because the vacuum sealer will generate heat when sealing, use for a long time, the sealing seat with continue to heat, when the temperature is too high, the plastic case may be deformed. If just for household or small amounts of use, a Non-nozzle vacuum sealer can be purchased in a plastic case.   It's a factory or a long-term operator, it's recommended to purchase a Non-nozzle vacuum sealer with a stainless steel housing, in addition to not worrying about the deformation of the sealing seat due to high temperature, the vacuum pump installed inside is larger than the Non-nozzle vacuum sealer with plastic casing, continuous use is not afraid of failure, and the vacuuming ability is also strong. Compared with the Chamber vacuum sealer, Non-nozzle vacuum sealer is much smaller and easy to carry. Please pay attention to the vacuum bag. Non-nozzle vacuum sealers can't use vacuum flat bags, due to the machine structure, Non-nozzle vacuum sealers are available for vacuum embossed bags (vacuum stripe bags), nylon gusset vacuum bags, aluminum foil gusset bags, and back seal bags. The price of vacuum embossed bags and gusset bags are slightly higher than that of vacuum flat bags, so please pay the attention. If the product packaging itself is to use the gusset bag, such as tea leaves, rice, etc. A Non-nozzle vacuum sealer is highly recommended as the results are satisfactory. If you don't care about the price of vacuum bags and hope the price of the vacuum sealer is lower, a Non-nozzle vacuum sealer will be a good choice. 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.
