The Innoseal® Bag Sealer is suitable for closing all kinds of plastic bags. Thanks to the larger throughput, the L-sealer is also suitable for closing paper window bags, in which bread is packed. When you run the bag through the sealer and apply the bag sealer, the Innoseal® Standard Sealer Side Knife allows you to easily trim excess material from the twisted portion of the bag. The Innoseal® Side Knife is made of plastic; the blade itself is made of hardened steel.
