If your Bag Sealer isn’t working as well as it once was, chances are you don’t need a new sealer – just a new blade. These razor sharp replacement cutting blades are specifically designed to suit our Automatic Bag Sealers (DDI000160 & MABSCSS). Bag sealers are designed to quickly and easily tape plastic bags, produce bags, ice bags bread bags and more closed, saving time at the register and in pre-packing departments.
