Choosing the Right Vacuum Sealer: Universal vs. Specific Bag Models Explained The main difference between universal vacuum sealers and specific bag vacuum sealers lies in their adaptability to materials and types of vacuum seal bags. These differences directly affect the vacuum sealer's range of use, flexibility, and cost-effectiveness.   Universal Vacuum Sealers Universal vacuum sealers, as the name suggests, are machines that can use vacuum seal bags of various materials and thicknesses. The main advantage of these sealers is their versatility and flexibility. 1. Universal vacuum sealers usually have an open sealing area where users can place food or other items before starting the vacuum sealing process. 2. When using a universal vacuum sealer, there is typically no need to choose a specific size or type of sealing bag, as they can adapt to different sizes and types of bags. 3. This type of sealer is generally more suitable for home use, as they are simpler and more convenient to operate, requiring less setup and adjustment. 4. Versatility: They can use bags of various materials, including PE, PA, PET, etc., without restrictions on the material of the sealing bag. 5. Cost-effectiveness: Since cheaper, generic bags can be used, it may be more cost-effective in the long run. 6. Broad applicability: Suitable for packaging a wide range of needs, whether food or non-food items.   Specific Bag Sealers Specific bag sealers are machines that can only use vacuum seal bags of a particular material or brand. These sealers are often designed for special bag materials or specific sealing needs. 1. Specific bag vacuum sealers require the use of particular sizes and types of sealing bags. Before use, users need to place food or other items into the sealing bag, then insert the bag's opening into the sealer for sealing. 2. This type of sealer typically offers more sealing options, such as different sizes of sealing bags, wet and dry sealing, etc. 3. Specific bag vacuum sealers are generally more suitable for commercial use or situations requiring a lot of sealing, as they can provide higher efficiency and more options. 4. Specialization: Requires the use of specific materials or brands of bags, which are usually designed to fit the machine's sealing method. 5. Cost: The cost of specialized bags is generally higher than that of generic bags, which may increase the long-term cost of use. 6. Quality control: Using specialized bags may result in better quality control and sealing effects, as the machine and bags are designed as an integrated system.   Considerations for Choosing Between Universal and Specific Bag Vacuum Sealers 1. Cost: Consider the initial investment and the long-term cost of use. 2. Usage needs: Choose a more flexible universal vacuum sealer if your sealing needs involve frequently changing bag types, or a specific bag sealer if you have higher requirements for sealing quality. 3. Convenience of operation: Universal vacuum sealers are generally simpler and more convenient to operate, as they have less strict requirements for the bags.   In summary, choosing between a universal vacuum sealer or a specific bag vacuum sealer should be based on your sealing needs, budget, and quality requirements. If you need higher flexibility and cost-effectiveness, a universal model may be a better choice; if you have higher requirements for sealing effects and do not mind the cost of specialized bags, then a specific bag model may be more suitable. g   Choosing the Right Vacuum Sealer: Universal vs. Specific Bag Models Explained

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.   ※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.
