Is pass box necessary for primAry packing materials like bottles and ropp caps also?
Generally, pass box is necessary to transfer the material from one cleanliness class of room to the other class of room or from uncontrolled area to the controlled area and vice a versa. This is to avoid contamination. For material transfer in the same cleanliness class areas pass box is not required.
you are right sir but we are having pass box in our facility only for foils and pvc rolls.so my concern was whether to start the same procedure with bottles etc.
