Two-Ply Belts, commonly know as Band Sealer Belts, are small belts that are manufactured by laminating two layers of PTFE fabric together. Using a staggered splice, the belt has a smooth and continuous thickness throughout the belt length. These belts are commonly used in both plastic bag production and in packaging operations. 

AFC has also engineered a high-performance two-ply that uses proprietary composite technologies. This gives better release properties and longer belt life. This material combination results in higher strength and better overall flexibility. Various thicknesses and material types are available for AFC's custom engineered two-ply belts.
