Manual sealer (pliers) with constant heating, a sealing length up to 400 mm, and a 10 mm wide embossed seam. The sealer uses continuous heating, and the temperature is set with a thermal regulator. Both the upper and lower jaws are Teflon-coated and seal from both sides, ensuring a secure seal for extra-thick films or multi-layer folded films. The sealer can be used for sealing both ready-made bags and tubular or sleeve film. Convenient and easy to use, with a relatively low weight. Suitable for businesses in almost any industry.
