HAH - Hot Air Heat Sealing
Hot Air Heat (HAH) technology uses precisely controlled streams of heated air to create continuous, high-integrity welded seams without direct contact between the heating element and the packaging material. Designed for continuous sealing applications, HAH delivers reliable, repeatable performance across a wide range of flexible packaging materials. Furthermore, HAH minimises product contamination and seal defects.
The HAH Sealing Process
During the sealing process, heated air is directed through the sealing head and precisely applied to the weld area. Because heat is transferred by a controlled stream of hot air rather than direct contact with a heated sealing element, consistent energy is delivered exactly where it is required to form a continuous welded seam.
The non-contact sealing process helps minimise marking and contamination of the packaging material while maintaining consistent weld quality throughout continuous production. Optional cooling can be incorporated where required, with every HAH system configured to suit the material, production speed and application.
Available as complete sealing systems or individual components, HAH can be integrated into new machinery or retrofitted to existing production lines, with sealing lengths and operating speeds tailored to individual manufacturing requirements.
Why HAH Technology?
Contactless Heat Delivery
Precisely controlled streams of hot air transfer heat directly to the sealing area without contact between the heating element and the packaging material.
Continuous Production
Designed for continuous heat sealing applications, delivering reliable welded seams at production speeds of up to 50 m/min, depending on the application
Flexible System Configuration
Available as complete sealing systems or individual components for retrofit applications and new machine builds, with configurable sealing lengths and optional cooling
Reliable Seal Quality
Accurate heat delivery and controlled airflow produce consistent, high-integrity welded seams across a wide range of flexible packaging materials
HAH Technology in Action
HAH technology delivers consistent seal integrity across high-speed
production environments.
Retrofittable for Existing Packaging Lines
HAH technology can be integrated into existing machinery, providing manufacturers with a cost-effective way to upgrade or adapt continuous sealing processes without replacing complete production equipment. Systems can be supplied as individual components or complete sealing assemblies to suit existing machine layouts and production requirements.
Our engineers work closely with customers throughout specification, installation and commissioning to ensure every HAH system is configured for optimum performance, reliable operation and straightforward integration into existing production lines
Configured for OEM integration
For new machine builds, HAH can be supplied as a complete sealing package including sealing heads, temperature control systems, power supply components and application-specific hardware. Every system is engineered around the individual machine design to deliver reliable sealing performance, straightforward integration and long-term operational reliability.
Working alongside OEMs and machine builders, our engineers configure each system to meet the required production speed, sealing performance and product specification.
Applications and Material Compatibility
HAH sealing technology is designed for continuous flexible packaging applications where reliable, non-contact heat sealing is required. Typical applications include polyethylene bag sealing, industrial liners, food packaging, powders, chemicals and other continuous manufacturing processes where consistent weld quality and production reliability are essential.
Compatible with a wide range of thermoplastic materials including PE, PP, PS, PET, PVC, laminates, biodegradable and compostable films, HAH provides reliable, continuous sealing performance across diverse packaging formats while maintaining consistent weld quality throughout production.
