I want to know about primary packing area under which class and what is the pratical size distribution of this area. And what is the main difference between primary packing area and secondary packing area
Primary packing area is that where product is direct contact with packing materials such primary packing materials are bottles, tubes, etc. now if your product is sterile and filling is done in bottles then primary packing area must be Grade A means under LAF and surround by Grade B environment. now secondary packing area should be controlled area with temperature and humidity. secondary packing area is that where filled bottles, or tubes are packed in cartons, or in master box.
