Molded Pulp Medical Packaging FAQ: Sterilization and Compliance

Can molded pulp be used for medical packaging?

Yes. Molded pulp is used for medical device trays, surgical instrument holders, vial and ampoule trays, and protective packaging for diagnostic equipment. Its cushioning protects fragile medical products, and fiber can be engineered for specific sterilization and cleanliness requirements.

Can molded pulp packaging be sterilized?

It depends on the method. Molded pulp is compatible with EtO (ethylene oxide) and gamma sterilization in many applications, though gamma can embrittle fiber at high doses. It's not suitable for steam autoclave sterilization. Confirm the sterilization method with your supplier before specifying.

What standards apply to medical packaging?

Medical packaging falls under ISO 11607 (packaging for terminally sterilized medical devices), which governs validation of the packaging system. Depending on use, additional standards for biocompatibility (ISO 10993) and cleanroom manufacturing may apply. Work with a supplier experienced in regulated medical packaging.

Does molded pulp need a cleanroom for medical use?

For many medical applications, yes — molded pulp for device contact is often produced in controlled or cleanroom conditions to control particulate and bioburden. Specify your cleanliness class requirement (ISO 7 or ISO 8, for example) early, as it affects the production line and cost.

Why choose molded pulp over plastic for medical packaging?

Molded pulp offers comparable protection with a lighter weight, a renewable-fiber story, and a lower tooling cost for custom shapes. For single-use medical packaging, it also reduces plastic waste — increasingly important as hospitals and regulators push sustainability in healthcare supply chains.
