The Performance Qualification (PQ) carried out as part of the initial validation and for re-validation requires determination of the seam strength. Seal samples can be created precisely at the required width of 15 mm using sample cutters. These are then clamped into the testing machine or adaptive testing device and peeled at a monitored speed of 200 mm/min. The strength curve and maximum strength are recorded. Clamp kit for blister packs on request.
