Sealer Sales OnPak Gen 3.0 Ultrasonic Clam Shell Sealer, 3mm x 6mm Weld Area, 110V/220V

The Sealer Sales OnPak Gen 3.0 is a handheld ultrasonic clam shell sealer designed for closing food-service clam shell containers and similar plastic packaging without staples or glue. The 57kHz oscillating frequency creates the weld through ultrasonic vibration with a 3mm x 6mm effective welding area, and the handset stays cool so the operator can weld safely without burn risk.

Quick and Safe Ultrasonic Sealing

The ultrasonic mechanism creates the weld in less than a second with no heat from the handset. The result is safer than heat-tip alternatives (no burn risk to operator) and faster than mechanical fasteners (no staples to load or fingers to keep clear of). Designed for production-rate clam shell closure.

Ideal for Food Safety - No More Staples

Replaces the staples traditionally used to close clam shell food containers. The ultrasonic weld eliminates the food-safety concern about stray staples ending up in product, which is the standard worry that food-service operators have with staple-based closure. Cleaner-looking packaging and lower risk of customer complaints.

Enhanced Packaging Presentation

The ultrasonic weld looks cleaner than tape, staples, or glue. Customers see a flush, professional closure rather than a visible fastener, which is what makes the OnPak the right pick for retail food, deli, and prepared-meal packaging where presentation matters.

110V or 220V Dual Voltage Compatibility

AC adapter accepts 100V to 240V (50/60 Hz), so the same unit deploys in US or international operations without voltage conversion equipment. Useful for operations running packaging in multiple countries off the same equipment standard.

Lightweight Handset for Production Use

The handset weighs 7 oz, light enough for sustained packaging sessions. The unit is connected to a separate AC adapter housing (1 inch x 5 inch x 2 inch), which keeps the handset weight minimal. Efficient packaging - no heat from the handset, no tool to wait for between welds.

3mm x 6mm Effective Welding Area

The 3mm x 6mm effective welding area is sized for clam shell closure points. The weld point is small enough to look like a clean spot weld rather than a wide seam, but large enough to hold the closure through normal handling and transport.
