OPL-Series large pouch sealing


The OPL-Series sealer comes in three different sealing jaw widths, 300mm, 450mm, and 600mm. This sealer utilizes an advanced processor to develop seal to seal consistency. ce-marking mark available.

OPL-Series extended length medical pouch sealer

This sealer utilizes a powerful, direct-drive electronic solenoid to deliver seal to seal force consistency for repeatable sealing. A thin film thermocouple sends thermal data from the sealing environment to finely manage sealing performance. Our medical device packaging machines are designed to be gentle on consumable parts for a low cost of ownership. Our simple step menu easily guides users through the setup process for rapid pouch changeovers. Our sealers are delivered from our ISO 17025 accredited laboratory for accurate calibration for our ISO 13485 medical device manufacturing customers. For years Van der Stähl Scientific machines have sealed billions of pouches through our network of worldwide users.


Our robust solenoid actuated sealing bar engenders seal to seal force by gating voltage through our advanced microprocessor. With our airless system you do not need to manage the complexities of validating the air source. Just plug into a power outlet and you’re ready to package your medical device.


Some of our OPL-Series customers have had their sealers for years and they are still running strong. Built heavy-duty with precision componentry, the OPL-Series are built for the long haul. Over a billion seals are created on our sealers each year worldwide through our network of users,  join our list of satisfied customers.


Our sealers ship to you from our fully accredited ISO-17025 calibration lab. We perform temperature calibrations at multiple internal thermal zones for better accuracy. Our optional “Pro calibration” certifies time output and checks the mechanical system’s force with a multi-zone force calibration.

OPL-Series pouch sealer

The OPL-Series medical device pouch sealers are available in 3 lengths up to 600mm to accommodate large pouches. The OPL-Series sealers can also be custom configured with upper and lower heating elements in order to seal heavy gusseted pouches. This sealer can seal a wide host of materials from foil, Tyvek®, poly, and nylon and ships with an included ISO-17025 accredited calibration.

OPL-Series Medical Pouch Sealer

The OPL-series medical pouch sealer ships to your doorstep with a free temperature calibration from our ISO-17025 accredited laboratory. Ask about our “Pro Plan” for force, time, and multi-temperature calibration to jump-start your packaging validation.

Extended length medical device packaging

The OPL-series medical device sealer creates a 10mm wide seal and can seal pouches up to approximately 23 inches wide. The sealer does not require an air supply as force is delivered through a powerful solenoid. The OPL-Series sealer can seal a variety of materials such as nylon, Tyvek®, Mylar, foil, and poly. The microprocessor allows for the adjustment of temperature, contact time and release temperature. Set the OPL-Series sealer to a semiautomatic mode for touch-free operation or activate with the foot or table switch for better user flexibility.
  • Password protected settings
  • Multi-zone internal calibration
  • Adjustable auto-cycle mode
  • Powerful solenoid
  • Airless system operation
  • Available in 300, 450 and 600mm

Consider the MS-350 sealer

The MS 350 medical pouch sealer does not use inexpensive air valves to actuate the critical force at the platen. Our custom-built solenoid is minutely controlled through the system’s advanced microprocessor. The low profile form factor makes an attractive addition to your cleanroom and is well-suited for wipe downs. Our intuitive step function microprocessor makes setup simple.

machine features that matter

Our powerful microprocessor managed solenoid system…

Our precision high force solenoid creates seal to seal accuracy to better manage your critical process. The OPL Series sealer is completely airless and only requires standard voltage for operation. With our new direct drive system, we can achieve greater force to accommodate a wider range of materials. We have removed multiple wear parts for longer duty cycles and less scheduled maintenance.

Thermal performance

Microprocessor delivered electrical gating delivers accurate platen temperature

Easy Setup

Intuitive menu steps and paddle keys make machine setup fast, accurate and simple.

Environment sensing

Our thin film temperature sensor accurately gathers the platens thermal environment.

Extended lengths

Three sealing lengths 300mm, 450mm and 600mm to fit a host of pouch sizes.

medical packaging begins with accredited calibrations


When developing your DOE (design of experiments) it is vital that you understand the value of all measured attributes. With our laboratory developed system, we can verify our machinery’s adherence to time set points. Understand all critical points for a stronger I.Q.


The amount of force that is being applied to your pouch needs to be understood to develop a cogent medical device packaging validation. With our precision transducers and advanced meters, we can verify critical machine force, and will provide easy to read reporting.

Thermal Calibration

The best medical device packaging validations are built on a machine calibration that explores the usable range of thermal performance. With our range calibration, we will verify packaging machine compliance at 3 temperatures for a more complete calibration.

Testing integration, the future of medical device packaging

Medical device packaging engineers agree the pathway to compliant device packaging is through regular testing and inspection. With our patented MS-451-PV medical device pouch sealing machine, seal performance is verified with the onboard testing and inspection system.
