Foot-Operated Constant Heat Sealers

A constant heat sealer maintains heated sealing surfaces during operation. The operator places compatible packaging between the jaws and applies pressure for the required sealing time. The correct combination of temperature, pressure, and contact time depends on the material and equipment instructions.

Constant heat equipment keeps its sealing surfaces heated during operation, while impulse equipment delivers heat during the sealing cycle. The appropriate method depends on the bag’s material and construction. If your film calls for impulse equipment, compare our foot-operated impulse heat sealers rather than assuming the two technologies are interchangeable.

Potential applications include compatible heat-sealable cellophane, foil laminates, and thicker poly materials. Suitability depends on the specific film, its sealing layer, total thickness, and the selected machine’s capabilities. Obtain the bag supplier’s sealing requirements and confirm equipment compatibility before ordering.

No. A foil appearance does not establish that a bag can be heat sealed or identify the settings it requires. Foil laminates need a compatible heat-sealing layer and a construction suited to the equipment. Confirm the complete material specification and test representative bags before production.

Choose a usable sealing length that spans the entire flattened bag opening. Include gussets and folds in your measurement, and allow practical room for alignment. Check the model specifications for the usable sealing area rather than relying only on the machine’s overall dimensions.

The 1/2″ measurement describes the width of the sealing band, while sawtooth describes its patterned surface. This differs from sealing length, which runs across the bag opening. Confirm that the resulting pattern and width meet your package requirements.

Use the packaging material supplier’s guidance and the equipment manufacturer’s instructions as your starting point. The listed 50°C to 300°C control range is not a recommendation to use the highest setting. Test the actual bag construction and adjust only as directed to achieve a consistent seal without burning, distortion, or damage.

No. The pedal operates the sealing jaws, but the operator still loads, positions, and removes the package. Keeping both hands available can help with alignment and support, but hands must remain clear of the heated jaws and pinch points during use.

Foot-operated equipment can support repetitive sealing tasks when its capabilities match the material and workload. Actual output depends on package loading, required contact time, handling, and the machine’s operating limits. Confirm the intended duty requirements before selecting equipment for a production station.

The equipment is described as capable of producing a hermetic seal with suitable materials and operating conditions. That does not guarantee every finished package will be airtight. Validate the complete bag and seal using testing appropriate to your product and application rather than relying on appearance alone.

Review the machine’s electrical requirements, footprint, working height, operating instructions, and required clearances. Plan how packages will be supported and moved through the station. Because the sealing surfaces remain hot during operation, follow the manufacturer’s precautions for warm-up, use, shutdown, and cooling.

Identify the exact machine model and confirm the required replacement components with the manufacturer or our team. Our sealer maintenance kits include model-specific options, but availability on that page does not establish compatibility with every constant heat sealer. Disconnect power and allow equipment to cool before maintenance, following the manufacturer’s instructions.

Yes. Contact Action Packaging with your bag dimensions, film or laminate specification, total sealing thickness, desired seal, and expected workload. Include any recommended temperature or sealing requirements from your bag supplier. You can also browse our bag sealers to compare other equipment types.
