Double impulse sealers are ideal for heavy duty applications.  We offer hand, foot, and automatic models and depending on the model, material up to 24" wide and 20 mil thick can be sealed with a 5mm wide seal.  The sealer uses 2 heating elements (upper and lower) to fuse the material from both sides at the same time.  This gives a faster and better seal for thicker or hard to seal material.

Easy to operate.  Set the timer, insert the bag between the sealing bars, press down on the foot pedal or handle and release after the timer goes off.
