A Materials Partner for Medical Packaging Converters

We supply the coating and stand behind it with documentation and engineering support. Package-level validation stays where it belongs — with you.

Documentation

COA with every batch. SDS and technical documentation available on request.

Sterilization Support

Formulated for excellent EtO compatibility. Final sterilization validation is performed at the packaging level by our customers.

Validation Support

Consistent batch-to-batch quality, seal-parameter guidance and joint testing support during your ISO 11607 validation runs.

Frequently asked: Are your coatings ISO 10993 certified? — Our products are materials for medical packaging, not finished devices. ISO 10993 biocompatibility applies to the finished device and is carried out by the converter. We support your testing with full material documentation (SDS, COA per batch). · Which sterilization methods are compatible? — EtO per internal and field testing; other methods can be evaluated with your team on request.
