Validatable Heat Sealer
Validatable Heat Sealer
A validatable heat sealer provides documented, repeatable seal parameters that satisfy ISO 11607 and audit requirements. Every machine we supply in this range comes with full IQ/OQ/PQ documentation, calibration certificates, and the parameter control needed for medical device and pharmaceutical packaging compliance.
What makes a heat sealer validatable
A validatable heat sealer differs from a standard machine in three ways: controlled parameters, documented outputs, and calibration traceability. Validation follows IQ/OQ/PQ protocols. Installation Qualification confirms the machine is correctly set up. Operational Qualification proves it seals within defined temperature, pressure, and dwell-time ranges. Performance Qualification demonstrates consistent results under production conditions.
ISO 11607 governs packaging for terminally sterilised medical devices. It requires that the sealing process is validated and that seal integrity is demonstrable. Standard impulse sealers lack the parameter control and data logging needed to satisfy these requirements. Validatable machines give you adjustable, lockable settings with calibration certificates that auditors can verify.
If you are packaging medical devices but do not need full validation documentation, a medical heat sealer may be sufficient. The distinction matters: validatable machines come with the documentation framework, while medical sealers are built to cleanroom standards without the formal IQ/OQ/PQ package.
Choosing between impulse, band, and power sealers
Validatable sealers come in three types, each suited to different throughput levels and pouch sizes. Impulse sealers like the Magneta 421 MGMIDS and 421 MGMT are bench-top machines handling 100–500 pouches per day. They seal sterilisation pouches up to 420mm wide and are the most common choice for sterile services departments and small medical device manufacturers.
The Audion AD666 MPCV is a continuous band sealer with a roller conveyor. It runs at 500+ pouches per day without stopping, making it the right choice for high-volume medical packaging lines. The continuous operation means no cooling cycle between seals.
Power sealers like the 1020mm and 720mm validatable models handle large-format pouches and heavy-gauge Tyvek packaging. If your pouches exceed 500mm in width or use thick sterilisation materials, a power sealer delivers the clamping force and seal length needed.
Comparing validatable sealer types
The table below summarises the three validatable sealer types. Your choice depends on daily volume, pouch size, and whether you need data logging for each seal.
| Type | Seal Length | Throughput | Best For | Validation Features | Price Range |
|---|---|---|---|---|---|
| Impulse (Magneta) | Up to 420mm | 100–500/day | Sterilisation pouches, small batches | Parallel seal bars, data logging (MGMIDS), calibration certs | £945–£2,449 |
| Band (AD666 MPCV) | Continuous | 500+/day | High-volume medical packaging lines | Roller conveyor, ISO 11607 documentation, continuous operation | £3,655 |
| Power (ISM range) | 720–1020mm | 200–500/day | Large pouches, Tyvek, heavy-gauge materials | Full IQ/OQ/PQ, adjustable pressure/temp/dwell, calibration certs | £6,999–£7,939 |
For most sterile services departments processing standard sterilisation pouches, the impulse range covers the job. Move to a band sealer when throughput exceeds 500 pouches per day. Move to a power sealer when pouch width exceeds 500mm or when sealing Tyvek and other heavy-gauge sterilisation wraps.
Validation documentation and compliance
Validation is a three-stage process. IQ (Installation Qualification) confirms the machine is installed to the manufacturer's specification and that utilities, environment, and setup meet defined criteria. OQ (Operational Qualification) tests the machine across its operating range to verify that seal temperature, pressure, and dwell time produce acceptable results at both ends of the parameter window. PQ (Performance Qualification) runs the machine under actual production conditions to confirm repeatable, compliant seals over an extended period.
The Magneta 421 MGMIDS adds integrated data logging. Every seal is recorded with time, temperature, and pressure data, creating an automatic audit trail. This is increasingly required by quality systems in pharmaceutical and Class III medical device manufacturing.
Calibration certificates are available for all validatable machines we supply. We recommend annual recalibration as a minimum, though your quality system may require six-monthly intervals. PackSealer can advise on the validation process, supply documentation templates, and coordinate with your quality team. Call 0121 704 0294 to discuss your specific compliance requirements.

"Wasn't sure which machine was most suitable for my requirements, phoned up and spoke to very friendly and knowledgeable staff member. Ordered a machine based on their advise and it's just what I needed. Would highly recommend."
"Such a helpful service. Chris really went above and beyond to help me when my pack sealer stopped working. Couldn't recommend highly enough!"
"Exceptionally obliging, required delivery urgently with company fulfilling my request. Very helpful chap that I spoke to. Order received next day. Would definitely recommend. Many thanks."
Common questions
A validatable heat sealer is a machine with controlled, adjustable parameters (temperature, pressure, dwell time) that can be formally validated through IQ/OQ/PQ protocols. It produces documented, repeatable seals that satisfy ISO 11607 and medical device packaging audit requirements.
If you are packaging terminally sterilised medical devices, ISO 11607 requires that your sealing process is validated. IQ/OQ/PQ documentation proves your machine is correctly installed, operates within specification, and performs consistently under production conditions. Pharmaceutical and Class III medical device manufacturers typically need full validation.
A medical heat sealer is built to cleanroom standards with stainless steel construction and hygienic design. A validatable heat sealer goes further: it includes the parameter control, data logging capability, and documentation framework needed for formal IQ/OQ/PQ validation. All validatable sealers are medical-grade, but not all medical sealers are validatable.
Yes. Calibration certificates are available for all validatable machines we supply. These confirm that temperature, pressure, and timing parameters are accurate and traceable to national standards. Contact us on 0121 704 0294 to discuss calibration requirements for your specific machine.
We recommend annual recalibration as a minimum. However, your quality management system may require six-monthly intervals, particularly for high-volume production or Class III medical devices. After any maintenance or seal bar replacement, recalibration is advisable before resuming validated production.
