Sealer Sales OnPak Dot-Line Ultrasonic Sealer, 110V/220V Handheld

The Sealer Sales OnPak Dot-Line is a handheld ultrasonic sealer that welds non-woven materials, nylon bags, bubble wrap, and aluminum bags without using heat. The 57kHz oscillating frequency creates the weld through ultrasonic vibration rather than heat, which means no warm-up time, no burn risk to the operator, and no thermal damage to the substrate.

Ultrasonic Welding, No Heat from Handset

The ultrasonic welding mechanism creates the bond through high-frequency vibration that fuses the substrate molecules at the contact point. No heat radiates from the handset, which means no burn risk and no thermal degradation of heat-sensitive packaging. This is the difference between safely welding next to bare hands and needing safety gloves to handle a hot-tip alternative.

Welds Non-Woven, Nylon, Bubble Wrap, Aluminum Bags

Compatible substrates include non-woven materials, nylon bags, bubble wrap, and aluminum bags. The ultrasonic mechanism works across this range without configuration changes; the same unit handles different materials by adjusting only the contact dwell time per weld.

Alternative to Tape, Staples, Rubber Bands, or Glue

The dot-line weld replaces the tape, staples, rubber bands, or glue traditionally used to close non-woven and similar packaging. The weld is cleaner-looking than any of these alternatives, faster than glue, and does not introduce foreign material (no staples to find in food packaging, no adhesive residue on the substrate).

Lightweight Handset, Easy to Maneuver

The handset weighs 7 oz, light enough to use for sustained packaging sessions without operator fatigue. The unit is connected to a separate AC adapter housing (1.1 inch x 5 inch x 2.1 inch), which keeps the weight at the handset minimal. The operator can weld quickly without lugging around a heavy unit.

Dual Voltage Configuration

AC adapter accepts 100V to 240V (50/60 Hz), which makes the same unit deployable internationally without voltage-conversion equipment. Useful for operations running packaging in multiple countries off the same equipment standard.

Good Design for Smart Packing

The OnPak is designed for production packaging operations where speed and cleanliness matter more than the maximum weld strength a tabletop sealer would deliver. Use for retail packaging, deli sealing of non-woven, and any application where the closure needs to look clean and hold the package shape through retail handling.
