Band Sealing Machine is ideal for high-volume packaging and sealing thermoplastic materials like polyethene, plastic-lined, foil and gusseted bags of almost any size or length. Operating speeds can be set lower or higher without wear to the sealer. Band Sealing Machine works by filling nitrogen gas into the package to preserve its longevity and then seals the packaging content. This nitrogen-filling system is commonly used for packing food equipment. It is also known as the Sealing Band Gas Flushing Unit.
