What Is an Impulse Heat Sealer?
An impulse heat sealer is a device that uses a brief surge of electrical current to heat a sealing wire, which then thermally bonds materials together. This method is particularly effective for sealing plastic materials.
Its operating principle is straightforward: when activated, a short, high-current impulse is sent through a heating element or wire. This rapid heating is sufficient to melt and seal the adjoining surfaces of the material being sealed. Once the current stops, the material cools and solidifies, forming a secure seal.
Impulse heat sealers are widely used in various industries, including food packaging, industrial product packaging, and medical supplies packaging. They are particularly effective for sealing bag openings. Notable features of these sealers include their ability to minimize heat transfer, thanks to the brief heating period, and their capability for precise sealing. They are also compatible with a wide range of materials. For optimal results, it’s important to choose a sealer appropriate for the material and to adjust the sealer settings accurately for the specific sealing task.
