ME300HI 300mm Impulse Heat Sealer – MEC Brand

The MEC ME300HI is a high-quality, hand-operated desktop impulse heat sealer with a 300mm sealing length and a 2.5mm wide seal. The ME300HI 300mm heat sealer is ideal for sealing larger bags and pouches across a wide range of industries. This compact yet heavy-duty sealer is perfect for low to medium-volume packaging environments that demand consistent, professional results.

This 300mm heat sealer delivers a strong 2.5mm-wide seal using impulse sealing technology. This means it only consumes power when the sealing arm is engaged, making it energy-efficient. The unit heats instantly upon engagement and cools quickly. This allows for fast repetition in batch sealing environments. The built-in control timer allows the operator to adjust the sealing heat according to the bag thickness.

The ME300HI is well-suited for sealing polyethylene (PE), polypropylene (PP), BOPP, foil pouches, laminated materials, and other thermoplastic bags. The maximum bag width one can use with this sealer is 300mm. For sealing wider bags explore our range of larger sealers here.
