PackworldUSA Highlights the Versatile and Precision-Driven 3400 Series Heat Sealer

A Precision Heat Sealer Offering Unmatched Cleanroom Compatibility and Versatile Sealing Solutions for Critical Packaging Applications

PackworldUSA, a leading manufacturer of precision heat sealing equipment, highlights the 3400 Series Heat Sealer, designed to meet the demanding standards of industries requiring precision packaging solutions. From the life sciences to the packaging sectors, this advanced system offers unmatched versatility, cleanroom compatibility, and ease of use. The 3400 Series Heat Sealer is manufactured from cleanroom-friendly materials such as stainless steel and anodized aluminum, ensuring it meets strict sterility requirements. The design eliminates the need for fans, reducing the risk of aerating particulates, and is wipe-down ready for standard cleanroom sterilizing solutions. This makes the system ideal for environments requiring high levels of cleanliness, such as medical devices and pharmaceutical packaging.


The 3400's intuitive touchscreen control panel simplifies the programming and monitoring of all sealing parameters, including time, temperature, and pressure. With real-time display capabilities, operators can easily verify critical process parameters, ensuring consistency and reliability in the sealing process. For added security, the 3400 Series includes password protection, preventing unauthorized changes to machine settings or critical process parameters to maintain seal integrity and ensure operation within validated parameters.

The 3400 Series offers a range of features to accommodate various packaging needs. The optional vacuum/purge system allows for customizable cycles, enabling product packaging to be tightly sealed or gently packed to reduce bulk without damaging the product. The system supports multiple cycles of alternating vacuum and purge functions and can be programmed to end on either cycle, offering flexibility to operators in achieving the desired result. Additionally, the compressed air exhaust outlet can be vented out of the room for even more cleanroom compliance.

PackworldUSA's 3400 Series is powered by the TOSS® PIREG® Variable Resistance Control, a hallmark of their precision heat sealing systems. This technology eliminates the need for thermocouples, allowing the machine to achieve the specified sealing temperature within milliseconds while maintaining precise control throughout the sealing process. Available with single or dual bands, the system can easily accommodate thick films requiring heat from both jaw bars, providing even heating for the most challenging applications.

Ensuring the highest standards, the 3400 Series is fully validatable, ISO 11607 compliant, and offers test ports for verifying the functionality of critical process parameters, such as temperature, time, and pressure. Operators can confidently maintain the integrity of every seal, even in the most demanding applications. The 3400 Series also features the exclusive AUTOCAL function for automatic zero calibration and multi-point calibration, making temperature calibration more straightforward than ever before.

Available in both 16-inch and 24-inch models, as well as custom sizes, the 3400 Series accommodates a wide variety of package sizes. Optional water-cooled jaws allow for faster cooling cycle times, minimizing overall sealing time, and the system is equipped with an emergency stop button for added safety. Whether sealing delicate medical packaging or bulky industrial products, the 3400 Series can be configured for optimal performance.

The system includes a recipe storage feature that enables quick setup for different materials, ensuring minimal downtime between production runs. A resettable seal counter helps operators track production output and schedule maintenance efficiently. Additionally, graphical displays provide real-time feedback on temperature, time, and pressure, complete with visual and audible alarms to alert operators of potential issues and ensure consistent quality.

PackworldUSA stands behind its products, offering a 30-month warranty on all parts excluding consumables. All machines are fully built to the company's exacting standards, ensuring they meet the rigorous demands of packaging engineers, process engineers, and quality assurance professionals alike.
