  What is Impulse Sealer Heating Element?   A Heating Element is a key component in impulse sealers, which are devices used to seal plastic bags and other thermoplastic materials. Here are the main points about this element:   Function: The heating element generates heat when an electrical current passes through it, which melts the thermoplastic material to create a seal.   Material: The heating elements are typically made from a nichrome wire (an alloy of nickel and chromium) because of its high resistance to electricity and ability to withstand high temperatures without breaking down.   Operation: In impulse sealers, the heat is only generated when the sealer is in operation (i.e., when the handle is pressed down), which means the wire is only heated for short periods. This helps prevent the wire from overheating and extends its lifespan.   Replacement: Over time, the heating element can wear out due to repeated heating and cooling cycles. It may need to be replaced to maintain the sealer's effectiveness.   Installation: Replacing the heating element typically involves removing the old one, cleaning the sealing bar, and then carefully installing the new one to ensure it is taut and properly positioned.   This component is crucial for the proper functioning of impulse sealers, widely used in packaging industries to ensure seals.

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.

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. While PE bags may suffice for short-term or less critical applications, vacuum bags offer a more robust solution for long-term freshness and protection.
