Various types of sealers on the market have different features and operating methods, how to choose a sealing machine that is easy to use and suitable for you. The following are divided into two types according to the heating method of the sealing machine: Impulse heat sealers and Constant heat sealers are introduced.   Impulse heat sealers can set sealing time to heat. When the operator presses the handle to touch the micro switch, heating element will be heated and when reaching the set sealing time, power off automatically, the heating element is no longer heating. The impulse heat sealer can be divided into single heating and double heating. The applicable materials are as follows: Single heating: plastic bags, such as PE, PP, non-woven bags etc. Double heating: aluminum foils gusset bags (such as tea bags), vacuum bags, sterilization bags, and thick bags.         The width of the heating element of the impulse heat sealer is divided into 2mm/2.7mm, 5mm and 10mm. If you want to fuse without leaving an edge, you need to choose a round wire: 0.6mm/0.8mm. Consumables for Impulse heat sealer include heating element, Teflon cloth, and Teflon tape. Different types of sealing machine, such as hand type sealers and foot type sealers, use the different size Teflon tape or Teflon cloth. Please ask for details of consumables when purchasing. Tips: 1.      Different bags require different heating time. We suggest the users set the short time in the beginning. If the sealing line is not complete, the user can set a little longer sealing time. Please don’t set the maximum sealing time in the beginning. If the sealing time is too long, the bags will be melted. It will also shorten the life of the heating element. If the sealing line melts, please decrease the sealing time. 2.      When the sealing time of the sealing machine reach the target time (the red light is off), stay for a few seconds for the cooling time and then release the handle, the sealing line will be beautiful and complete. 3.      If the heating light indictor is on, but the heating element can't heat up. Please check the heating element, maybe the heating wire is broken. The user can take off the Teflon cloth first to check the heating element. If the Teflon cloth is burnt black, even burned, please replace the Teflon cloth. If the user doesn’t change the new one, it might make the heating element broken fast.     Constant heat sealer is temperature controlled sealing machine. After turning on the power, it needs to warm up for 5-10 minutes. When the temperature of the sealing seat reaches the set temperature, it will maintain constant temperature. Constant heat sealers use heating tubes or heating plates for heating. Because the heating bars maintain the high temperature, be careful when operating the constant heat sealers. Please don't touch the heating bar to avoid burns. There are three patterns of sealing line: net pattern (cross pattern), stripes pattern, and flat pattern. More people choose cross patterns. The constant heat sealer is available for aluminum foil bag, vacuum nylon bag, tinfoil bag, sterilization bag. Please don’t use the constant heat sealer to seal PE, PP and other plastic material bags. The bags will melt and stick to the heating bar. It will be hard to clean up the heating bar, and might make the sealing line incomplete. The width sealing line of constant heat sealer is 10mm and 15mm.   Tips： The different materials bags are suitable for different temperatures. We suggest the users start to seal the bags by low temperature. If the sealing line is not complete, it means the temperature is not enough, please set a little higher temperature. If the sealing line melts, indicates the temperature is too high, please turn down the temperature. When the users adjust the higher or lower temperature, please wait the few seconds to let the current temperature to reach the setting temperature.

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) 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 our product.   ※  Nozzle vacuum sealer         At present, the nozzle vacuum sealer is widely used in the electronics industry. The Nozzle vacuum sealer and Non-nozzle vacuum sealer are also external, The difference is that the nozzle vacuum sealer uses the nozzle to extend into the vacuum bag to extract the air. Available for vacuum flat bags and aluminum flat bags. Non-nozzle vacuum sealer without a nozzle. Therefore, only the strips of the vacuum stripe bag can be used to create a pipeline to allow the air to be drawn out. The reason why the nozzle vacuum sealer has a nozzle, after the vacuum, the nozzle must be retracted into the machine and can be sealed, so when the nozzle moves, a little air enters. Therefore, the vacuum degree of the nozzle vacuum sealer is lower than that of the other two vacuum sealers.         The nozzle vacuum sealer is divided into the pneumatic type and electromagnet due to the driving mode. The advantage of the pneumatic nozzle vacuum sealer is the low sound, the disadvantage is that you need to connect the air compressor. The electromagnetic nozzle vacuum sealer doesn't need to be connected to an air compressor, but the sound is loud during operation.         Most Nozzle vacuum sealers are designed for products with little moisture or powder, add a water filter, keep water and powder in the water filter, Don't allow moisture and powder to flow into the machine, and Avoid damage to parts. If the product itself is water or powder, never choose a Nozzle vacuum sealer, because when pumping, the nozzle extends into the vacuum bag, it will directly remove the water and powder, It's recommended to choose the Chamber vacuum sealer, when the Nozzle vacuum sealer in operating, the way the nozzle is placed and the position of the product are very important, related to the vacuum effect. When the vacuum is recommended, keep the nozzle as close as possible to the product, and avoid sticking vacuum flat bags when pumping, this causes the nozzle to be unable to pump air, but be careful that the nozzle is not blocked the product, it can't be pumping. When operating the Nozzle vacuum sealers, please pay special attention to this technique.         Same to a Non-nozzle vacuum sealer, there are plastic casings for sale in the market. Nozzle vacuum sealer with metal shell (steel plate with powder coating and stainless steel), small size vacuum sealer with plastic casing, cheap price, but long-term operating with high frequency, it's not recommended to buy the Nozzle vacuum sealer with a plastic casing, because the vacuum sealer will generate heat when sealing, use for a long time, the sealing seat with continuing to heat when the temperature is too high, the plastic case may be deformed. Just for household or small amounts of use, a Nozzle vacuum sealer can be purchased in a plastic case. If it's a factory or a long-term operator, it's recommended to purchase a 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 Nozzle vacuum sealer with plastic casing, continuous use is not afraid of failure, and the vacuuming ability is also strong.         The Nozzle vacuum sealer is available for a vacuum flat bag, cheaper than a vacuum stripe bag. However, due to the control of the nozzle entering and leaving, the structure is more complicated than the Non-nozzle vacuum sealer. Therefore, the price of the Nozzle vacuum sealer is higher than that of the Non-nozzle vacuum sealer, price comparison with the Chamber vacuum sealer depends on the vacuum pump built into the Chamber vacuum sealer, Nozzle vacuum sealers are more expensive than Oil-less type Chamber vacuum sealer, but is lower than the oil type Chamber vacuum sealer.         Generally, there is only one nozzle of the Nozzle vacuum sealer, it can add nozzles and inflatable functions according to customer needs, most of them are filled with nitrogen, option to pump first and then inflate, or function settings such as inflate and then pump after pumping. In addition, there are also inflatable sealing machines that only inflate, it also uses a nozzle to fill the gas into the vacuum bag. The inflatable has moisture-proof, the advantages of retaining freshness and anti-collision, mostly used in the food industry.         The Band sealer also develops the air extraction function, it also uses the nozzle to suck out the air, which belongs to a Nozzle vacuum sealer, generally known as a Continuous vacuum sealer. The price is much higher than other types of vacuum sealers, and the structure of the Band sealer will also affect the vacuum degree, so the price is also different, to choose a Continuous vacuum sealer, except for the price, the vacuum degree is also a factor to consider.   When purchasing a vacuum sealer, factors to consider include price, the types of vacuum bags it can use, 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.  

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. "How to choose a vacuum sealing machine", please check the following website address. *Nozzle type vacuum sealer: https://www.dailysealing.com/news_detail.aspx?seq=1116 *Non-nozzle type vacuum sealer: https://www.dailysealing.com/news_detail.aspx?seq=1115 *Chamber vacuum sealer: https://www.dailysealing.com/news_detail.aspx?seq=1114   2.     Why can't I use PE bags for vacuum packaging? 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.
