Vacuum Packaging

Explore the technical advantages of vacuum packaging for stabilizing delicate or sharp medical devices. This section highlights the features of the V46010 validatable vacuum sealer, explaining how it maintains sterile barrier integrity without the need for external air sources.

Vacuum packaging removes air from the pouch before sealing, which stabilizes the device during shipping, reduces movement that can damage sterile barriers, and helps preserve sensitive chemistries used in combination medical devices. Vacuum packaging is especially valuable for devices with sharp edges, irregular shapes, or components that must remain immobilized.

ISO 11607 requires that sterile barrier systems maintain integrity throughout distribution and storage. Vacuum packaging reduces internal stress on the pouch, minimizes abrasion, and helps prevent seal creep or delamination. By stabilizing the device, vacuum packaging supports stronger, more consistent sterile barrier performance.

The V46010 is a fully validatable vacuum pouch sealer engineered specifically for medical device packaging. It provides precise control of vacuum level, seal temperature, pressure, and dwell time. Every unit ships calibrated through our ISO/IEC 17025 accredited laboratory, ensuring it is ready for validation the moment it arrives. This unit also does not require any external air.  It has a password lockout so validated settings can not be changed.

Devices with sharp edges, long profiles, delicate chemistries, or components that must remain immobilized benefit greatly from vacuum packaging. Orthopedic implants, combination devices, catheter systems, and diagnostic kits are common applications for the V46010.

Yes. The V46010 is designed for intuitive operation, rapid cycle times, and repeatable performance. Operators can quickly set validated parameters, and the system maintains consistent vacuum and seal conditions to support highvolume medical device packaging without the need for any external air sources.
