Silicone Seal Bar Assemblies
Learn about our assemblies, benefits and options.
Seals are applied to horizontal and vertical flexible packages with Seal Bar Assemblies. Thermally conductive Silicone Seal Bars (also referred to as “jaws”) work in partnership with a metal surface to form high-quality seals.
The silicone may appear at the top or the bottom of the assembly depending on part and machine geometries.
Thermally conductive, heat tolerant Silicone Seal Bar Assemblies provide superior heat sealing performance.
| Eliminate Leakers | Crowned designs eliminate air holes / leakers, Ideal for long seal bars |
| Eliminate Teflon Tape | Easy Release of Films, May Eliminate Need for Teflon Tape, High heat tolerance (288°C) means silicone won´t become sticky or gummy, Where small particle contamination is possible our Teflon Bonded Silicone provides adhesive-free alternative with up to 7x longer life |
| Heat Tolerant , Formulations | Silicone heat tolerant up to 288°C, High-Quality Seals |
| Superior Precision & Durability | Our continuous silicone has 4x superior thickness tolerances than extruded silicone, Our continuous silicone has 7x longer lifespan than extruded silicone |
| Market Leading Size Range | Industry leading size range of 2.5 to 280 cm in both flat and textured surfaces |
| Market Leading Bond Strength | Proprietary process chemically bonds silicone-to-metal and Teflon-coated silicone-to-metal without the need of messy adhesives |
| Ready to Use | Custom molded, eliminates machining of sheet materials |
| Compliant | Conforms to part thickness even on zippers and multi-layer films |
