PW4000 Series
Clean Room, Fully Validatable
Impulse Heat Sealer
PW4000 24" and 36" (Vacuum Optional)

The combination of the exclusive TOSS Technology—The Optimum Sealing System and Packworld's special jaw bar band material ensures that every machine we build delivers on our promise of Perfect Seals...Every Time.

The PW 4024 Heat Sealer provides the safety and assurance needed by the medical and other industries where perfect temperature control is essential.

Packworld Heat Sealers produce repeatable, high quality heat seals each and every cycle thanks to the TOSS Alloy-20® heat seal band. This allows us measure temperature across the entire length of the band to eliminating the lag between actual and measured temperatures. The instantaneous and continuous feedback permits high response for greater productivity.

Control System

The control system provides the safety and assurance required by industries when perfect temperature control is essential. Repeatable, high quality heat seals are made each and every cycle. The system utilizes the TOSS Alloy-20 C heatseal or cut and seal band as the temperature sensing means, thereby eliminating the lag between actual and measured temperatures. The instantaneous and continuous feedback permits high response for greater productivity.

Precision Heat Seal Control

The versatile impulse heat seal controller, RES-440, provides digital display of menu driven time/temperature profile with various time sequence possibilities. Time and temperature are keypad programmable with the cooling cycle controlled by either time or temperature. Actual temperature is displayed in real time and repeatable. Machine can be fitted with any one of over 300 different TOSS Alloy–20 heatseal bands or wires depending upon the results desired.

FDA/GMP Validation

Designed for validation, these heat sealers provide verification and feedback on all heat sealing parameters. Temperature and timing functions are set with keypad accuracy and can be verified with the display and with Data Capture with USB connection. Heat sealing time begins only after the prescribed temperature has been reached. The jaws remain closed until the heat seal cool down temperature is reached. Visual lock-out alarms alert the operator of functional problems. Heat sealing pressure is easily adjustable.

heat sealing headaches? NO MORE! eliminate them with Packworld USA. We take away the pain of heat seal failures.

Heat Sealing Technology

The Perfect Heatseal is achieved with absolute control over time, temperature, and pressure. Whereas the perfect repeatable temperature cycle is the most difficult to achieve, perfection cannot be achieved without a controlled pressure that is uniform over the full length of the sealed area.

heat sealing headaches? NO MORE! eliminate them with Packworld USA. We take away the pain of heat seal failures.

Perfect Seals

A perfect seal is one that does not allow microorganisms to enter (no channel leaks or other seal defects that can allow entry) and remains so during the rigors of processing (especially sterilization), storage, handling and distribution. (Seal integrity)

A perfect seal must be strong enough to withstand the rigors of handling and transportation and yet provide for convenient opening at the point of use. (Seal strength)

A perfect seal must be continuous without any visual defects. Visual inspections should be augmented with physical tests to assure uniformity and continuity.

Perfect Seals... Every Time - That's our promise!
