In medical packaging, not just any paper will do.
A packaging material may look similar to conventional paper, but if it’s being used to protect a sterile medical device, it must meet a very different set of performance requirements. Medical-grade packaging papers are engineered to maintain sterility, withstand processing and handling, and support regulatory compliance throughout the product lifecycle.
So, what actually makes a packaging material “medical-grade”?

It Starts with the Sterile Barrier
Medical packaging plays a critical role in protecting devices until they’re ready for use. To do that, the packaging material must provide a breathable barrier that allows sterilization agents to penetrate the package while helping prevent contamination afterward.
This balance between breathability and barrier performance is one of the defining characteristics of medical-grade packaging paper.
Strength Matters
Medical packages are subjected to high amounts of stress—from converting and sterilization to transportation, storage, and final use.
A medical-grade paper must provide the tear resistance, tensile strength, seal strength, and burst strength needed to maintain package integrity throughout that journey.
The Medidura™ portfolio uses polymer reinforcement within the cellulose fiber structure to provide improved mechanical resistance compared to non-reinforced medical packaging papers.
Porosity Is Carefully Engineered
Porosity is a critical performance characteristic. The material must allow sterilization processes, such as ethylene oxide (EO), to effectively reach the packaged device while still supporting sterile barrier performance. Different applications may require different porosity levels depending on the sterilization method and package design.
Getting the balance right is essential for both package performance and patient safety.
Cleanliness and Safety Are Critical
Medical packaging papers are also designed to minimize particulate generation during package opening.
For example, Medidura™ papers incorporate polymer reinforcement within the fiber matrix to reduce particulate release when opening sterile packages, ensuring aseptic presentation of single-use medical devices.
This is an important distinction between medical packaging materials and conventional paper products that were not designed for healthcare applications.
Regulatory Compliance
Performance alone is not enough. Medical packaging materials must also support compliance with industry requirements.
The Medidura™ portfolio is designed for EN 868 and ISO 11607 compliance, standards widely recognized for sterile barrier systems and packaging for terminally sterilized medical devices. Medidura™ Medical Papers are also made from FSC© Controlled Fibers.
Meeting these requirements helps ensure packaging materials are suitable for the demanding needs of medical device packaging applications.
The Medidura™ Difference
Medidura™ reinforced medical packaging papers are engineered specifically for sterile medical packaging applications—not adapted from general-purpose paper grades. The portfolio combines breathable barrier properties, mechanical strength, printability, and reduced particulate generation in a range of basis weights and configurations to meet different packaging requirements.
Whether the priority is higher tear strength, optimized porosity, enhanced sustainability, or reliable sterilization performance, Medidura™ provides medical-grade paper solutions designed with both performance and patient safety in mind.
More Than Just Paper
Medical-grade packaging paper is far more than a substrate. It is a critical component of the sterile barrier system that helps protect medical devices from manufacturing through to end use.
When strength, porosity, cleanliness, and compliance are engineered into the material from the start, manufacturers can package with confidence.

Frequently Asked Questions
What is Medical Packaging Paper?
Medical packaging paper is a specialized paper material designed for sterile barrier systems used in medical device packaging. It provides the combination of breathability, strength, and cleanliness required for healthcare applications.
What makes paper medical grade?
Medical-grade paper is engineered to meet requirements for sterility maintenance, sterilization compatibility, package integrity, cleanliness, and regulatory compliance.
Why is porosity important in medical packaging paper?
Porosity allows sterilization agents such as ethylene oxide to penetrate the package during processing while supporting sterile barrier performance after sterilization.
How is medical packaging paper different from regular paper?
Unlike conventional paper grades, medical packaging paper is engineered specifically for healthcare applications and must meet strict performance requirements related to strength, cleanliness, sterility, and compliance.
What are the benefits of reinforced medical packaging paper?
Reinforced medical packaging paper can offer improved tear resistance, burst strength, package integrity, and reduced particulate generation during opening.
