Food-safety certification for PET closures: the verified scope

Delta closures are covered by ISO 22000:2018. Delta’s separate FSSC 22000 V6 certificate covers PET preform injection and PET bottle blowing, not closures.

Two certificates, two product scopes

Delta’s PE closures are manufactured under ISO 22000:2018 (ABS Global; scope: manufacturing plastic packaging materials — PE closures). Delta’s separate FSSC 22000 V6 certificate covers PET preform injection and PET bottle blowing at the same site; it does not include closures.

What ISO 22000 controls for closures

The closure food-safety system covers hazard controls, hygiene, food-contact material controls, supplier management and lot traceability. Product-specific declarations and test records remain subject to the relevant closure, market and customer program.

Where the separate certificate applies

FSSC 22000 V6 applies to PET preform injection and PET bottle blowing. It must not be presented as a closure certificate unless the published certificate scope is formally extended.

Foam-liner controls

For lined oil and sauce closures, customer and audit review should verify the liner declaration of compliance, application-process validation and adhesion testing where applicable.

Torque validation

Application and removal torque limits are established from the approved drawing and customer application. Final acceptance requires engineering review and production validation for the selected closure and neck finish.

Audit documentation by product scope

For closure audits, Delta supplies the current ISO 22000 certificate and relevant product or lot documents. The FSSC 22000 V6 certificate is supplied only for audits covering PET preforms or PET bottle blowing.
