This type of sealer uses a heating element that is only activated when the sealing jaws are closed. A pulse of energy heats the element, which then cools down. This method is highly efficient as energy is only used during the seal, making it ideal for sealing thermoplastic materials such as polyethylene and polypropylene. A common application is sealing plastic bags.
Precise and rapid seals minimize energy consumption and product waste. This technology has become indispensable for various industries, ranging from food packaging to medical device manufacturing, due to its ability to create airtight and tamper-evident seals. Its development arose from the need for a more efficient and controllable sealing process than constant heat methods, contributing significantly to advancements in packaging and preservation.
