Description

Quick Pulse Heat sealing technology is a cyclic, seal and cut system which can be used on all thermoplastic films, and incorporates a unique seal bar and anvil design to create a narrow width seal for material savings with superior performance characteristics.

There are two stages to QPH sealing. The first stage is the cut and seal phase where the jaws close on the film, and the desired temperature of the heated bar is reached and maintained by a designated temperature controller. This is held for the required duration and then removed.

The second stage is the cooling phase of the process. The temperature of the sealed area is cooled rapidly by a stream of water through the sealing bar. The rapid heating and cooling process takes only milliseconds, and this facilitates fast cycling times and increases output.

This rapid heat-up and cool-down process allows higher fusion temperatures without overheating the material and the seal being weakened by subsequent handling.

This seal is typically 1-1.5mm wide, showing a film material saving of approximately 10% against traditional crimp seals on the cross seal alone. The QPH sealing system ensures that heat and pressure are applied evenly across the sealing surface, creating a completely fused, hermetic seal.

The unique blade and anvil design of the QPH system minimises cleaning and maintenance. The heat of the blade is carefully maintained and controlled; therefore film material is rarely burnt onto the equipment (as is common with crimp sealing jaws).

Range

Suitable materials: Polyethylene, Polypropylene, Polystyrene, Polyester, Polyvinylchloride, laminate, biodegradable and compostable films.

QPH sealing technology characteristics: Easily retrofitted, minimal cleaning and maintenance, no moving parts, user friendly, dramatically reduces downtime and demonstrates a longer service life

Benefits: High integrity, completely fused hermetic seals, film savings of up to 10%, reduction in film gauge of up to 25%.
