Choosing the Right Bag for Vacuum Packaging: PE Bags vs. Vacuum Bags Explained  When it comes to vacuum packaging, one common dilemma often arises: Should you opt for PE bags or vacuum bags? This question is prevalent among many, especially those new to the realm of vacuum sealing. The choice between PE bags and vacuum bags is not just about the cost but also about the effectiveness of the vacuum seal in various applications. Understanding the Need for Vacuum Packaging The purpose behind vacuum packaging can vary significantly. Whether it's extending the freshness of food, protecting items from rust and dust, saving space, or merely maintaining a temporary vacuum effect, the choice of bag plays a crucial role. Here, we delve into the characteristics of PE bags versus vacuum bags to help you make an informed decision. PE Bags for Vacuum Packaging: Pros and Cons PE bags, commonly seen in the market, are known for their accessibility and affordability. However, their ability to block air is not as effective as specialized vacuum bags. During the vacuum process, air may continue to seep into PE bags, preventing the formation of a true vacuum state. Despite this, thicker PE bags can maintain a vacuum effect for a short period. High-density PE (HDPE) bags can achieve a vacuum state post-sealing, but the duration of this effect is uncertain. If a long-term vacuum isn't your priority, PE bags might be worth considering, though testing their effectiveness for your specific needs is recommended. Vacuum Bags: The Optimal Choice for Long-Term Vacuum Sealing For those seeking a durable vacuum state, vacuum bags are the superior choice. Materials such as nylon (NY) and aluminum foil are particularly effective. PET bags offer another viable option, each material presenting distinct advantages depending on the items being packaged and specific user requirements. Selecting a Vacuum Sealer and Vacuum Bags: Guidance and Recommendations Concerned about which bags are compatible with your vacuum sealer? Wondering which material best suits your needs or whether the vacuum effect will be satisfactory? Daily Sealing is here to assist. We offer expert advice on choosing the right vacuum sealer and vacuum bags tailored to your requirements, ensuring your vacuum packaging process is as efficient and effective as possible. Conclusion Choosing the right bag for vacuum packaging involves considering the specific needs of your packaging requirements.

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          

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.
