Constant Heat Sealers

Constant heat sealers maintain a steady temperature at the sealing jaws, making them ideal for thicker materials that require prolonged, even heat. These machines are best suited for cellophane, foil-lined, poly-coated paper, Mylar, and multi-layer bags.

Unlike impulse models, these sealers stay hot while powered on. Operators should use caution and be aware of the heated surfaces during use.

This category includes handheld units for quick jobs, tabletop models for bench work, and foot-operated sealers for hands-free production. Whether you're sealing product packaging, coffee, medical kits, or specialty pouches, constant heat provides the reliability needed for clean, strong seals on challenging materials.
