WN-280F - W-Series Right Angle is ideal for high volume poly bag and other thermoplastic sealing. This sealer allows you to keep both hands free for quicker and more accurate sealing. The unit operates on impulse sealing and is controlled by a circuit board. These sealers are capable of 15-20 seals per minute. WN-280F is available as a 12" sealer with a 2.7mm seal. What sets this foot sealer apart from all other foot sealers is the position of the sealing jaw. Because the jaw is on the side, you can seal your bag anywhere...not just the top or bottom of the bag. This allows much more flexibility.
