Thermal Welding
Our MasterWeld series of sealing machinery can create exceptional welds 1.0" (25mm) and .5" (15mm) wide in materials for specialty bag manufacturing, crating, and vinyls used in sign production and geotextiles.
The open back on these units makes them excellent for inline splicing of rollstock. These machines have been effectively used for monolayer materials like polyethylene and laminated and coated structures with multiple layers of different materials.
