An impulse sealer with a 100mm (or 10cm) sealing length is a compact and versatile heat-sealing machine, commonly used for sealing plastic bags and other thermoplastic materials. The “100mm” refers to the maximum width of the seal it can create.
What is an Impulse Sealer?
An impulse sealer is a device that creates an airtight and watertight seal on thermoplastic materials (like polyethylene, polypropylene, PVC, and some laminated films) using heat. The key characteristic of an impulse sealer is that its heating element (a thin wire) only heats up for a very brief “impulse” when the sealing bar is pressed down. This is different from a “constant heat sealer” where the element remains continuously hot.
How it Works:
- Placement: You place the open end of your bag or film between the sealing jaws.
- Pressure: You press down the sealing bar/handle.
- Impulse Heat: An electrical current instantly heats the nichrome wire element, melting the plastic layers together.
- Cooling & Sealing: The current then immediately switches off, and the melted plastic cools and solidifies under pressure, forming a strong, permanent seal. A light or a “beep” usually indicates when the sealing cycle is complete.
- Release: You release the handle, and the sealed bag is ready.
Key Features of a 100mm Impulse Sealer:
- Sealing Length (100mm / 4 inches): This determines the maximum width of the bag or film you can seal. A 100mm sealer is ideal for very small bags, sachets, or pouches.
- Adjustable Heat Settings: Most impulse sealers have a dial to adjust the heat level (or sealing time). This is crucial for sealing different thicknesses and types of plastic films effectively without burning or having a weak seal.
- No Warm-up Time: They are ready to use instantly, as the heating element only activates on demand. This also makes them energy-efficient.
