    What Contaminants In Packaging Put Your Yields At Risk?

    Packaging can contaminate cleanroom gloves and controlled environments, putting your production at risk. Corrugated cardboard and chipboard are paper-based products that release fiber particles that are contaminants.

    Cardboard cartons are still efficient for transportation, distribution, and storage but the cardboard must not come into direct contact with cleanroom consumables or expose any of your cleanroom consumables to airborne fibers.

    Cleanroom compliant packaging

    Your cleanroom glove requirements and internal package handling process should address:

    • Carton liner:  Carton poly bag liners prevent loose fibers from the cardboard from contacting the outer poly bag containing the gloves. The bagged gloves are removed from the cardboard carton and carton liner in a non-critical area. Paper-based materials should not enter the donning or gowning area or the controlled environment.

    • Vacuum-sealed outer poly bag: Just like your critical equipment, cleanroom gloves are double-bagged. The outer bag can be opened in the transition or pass-through area. This outer bag should be vacuum sealed and nitrogen purged by the manufacturer to evacuate particles present in the packaging area.

    • Vacuum-sealed inner poly bag:  The inner bag can be opened for dispensing in the donning area. Like the outer bag, the inner pack should also be vacuum sealed and nitrogen purged during the packing process.

    • Proper stacking: The manufacturer should pack the gloves in flat, even stacks with thumbs inward so the wearers can easily grab the gloves by the cuff only for proper donning.



    Warning signs of noncompliant cleanroom packaging

    Cardboard or chipboard should never be in direct contact with your gloves. Cardboard, chipboard, or “box dispensed” gloves do not belong in a gowning area or in your controlled environment.

    If your supplier’s glove packaging does not isolate your gloves and your cleanroom processes from cardboard fiber contaminants, you need to source from a supplier with cleanroom-compliant packaging that does not put your critical process at risk.
