FAQs (Frequently Asked Questions) about vacuum packaging Vacuum packaging is currently a trend, and recently, many users have purchased vacuum sealers or vacuum bags, generating a lot of questions. Here are answers to the most commonly asked questions: 1.     Which vacuum sealer is suitable for me? A: There are many vacuum sealers on the market, and it is not easy to choose a suitable vacuum sealer. I have previously written about "How to Choose a Vacuum Sealer". Those with questions can refer to it for getting more information.

A: Due to the density of the bag material. Even after air is removed and sealed, air can still seep back into the bag. Therefore, after packaging, if left alone for a period of time, the vacuum effect will be lost.   3.     What type of bag material is suitable for vacuum packaging? A: The most common vacuum bag materials are nylon (NY) bags and aluminum foil bags. Both of these materials can prevent air from seeping back into the bag and maintain a vacuum state inside the bag.   4.     Why can't I maintain a vacuum effect even after using vacuum bags? A: If you have confirmed that you are using vacuum bags, you can first check if the seal is defective. Some vacuum bags are too thick and require a longer sealing time, such as foldable bags (tea bags), which have four layers. If the seal is confirmed to be perfect, check if there are any holes in the vacuum bag. When vacuuming, the bag will adhere closely to the contents. If the contents have sharp edges, it is possible to puncture the bag and lose the vacuum effect.   5.     Many users who have bought vacuum sealers or vacuum bags are confused when they find that they can't remove the air from flat vacuum bags. What should they do? A: This is because they have purchased a vacuum sealer without a nozzle. The non-nozzle type vacuum sealers have to use the special vacuum bags (channel bags, embossed bags and gusset bags) to remove air, so if users use flat vacuum bags, they will find the vacuum sealer and vacuum bag can't work.     6.     If someone accidentally purchases a non-nozzle vacuum sealer (such as FOODSAVER), what types of vacuum bags can they use? A: The following types of vacuum bags can be used: (1)    Vacuum sealer embossed bags (vacuum channel sealer bags): vacuum bags with straight stripes. (2)    Fold-over bags: such as tea bags with two sides folded in to become a four-layer bag. (3)    Back-sealed bags: vacuum bags with one side flat and the other side with an additional spine. Remember to choose aluminum foil bags and nylon bags as the material for vacuum bags.   7.     What is the difference between a vacuum flat bag and a vacuum striped channel sealer bag? A: A vacuum flat bag is like a regular plastic bag with both sides being flat are smooth, but the material of a vacuum flat bag is made of nylon (NY) or aluminum foil. A vacuum channel sealer bag has one flat smooth side and the other side has straight stripes.   8.     Why can a vacuum channel sealer bag be used with a Non-nozzle vacuum sealer? A: The key is in the straight stripes of the vacuum channel bag. The structure of a Non-nozzle vacuum sealer requires a straight stripe to create a channel for the air inside the bag to be removed. If the stripes are too shallow, it may still be unable to vacuum out the air.

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.

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.
