STUDY OF MOISTURE CONTENT ELIMINATION IN POLYPROPYLENE BLOOD BAG MANUFACTURING

Nowadays blood bag manufacturing industries are facing a problem in the drying process during the manufacture of blood bags. The drying process is meant to vaporize all the moisture content in the primary packing of the product to make it more sterile. But more than 30% of the blood bags are being rejected by the QA department due to the presence of moisture in the packing even after drying for about 6-8 hours. The presence of water droplets in the packing increases the chance for bacterial and fungal growth. The study was conducted for finding out the main causes for moisture retention in blood bag primary packing. Feasible remedial measures are suggested after analyzing the causes and effects. This will result in better productivity and enhanced quality control in surgical blood bag manufacture.
