Leakage of semi-rigid and flexible containers can be caused by faulty sealing or pinholes. Semi-rigid containers can be closed satisfactorily by removing product from the seal area during sealing. Biotesting indicates that pouches can be even more leakage-resistant than cans, provided the seal area is kept clean by proper filling. Careful handling keeps pinholes in these packs to an acceptably low level. Pouches experimentally punctured after processing result in low contamination provided they are immediately dried after cooling in chlorinated water. Large-scale production over several years of flexible pouches in Japan and semi-rigid containers in Europe has resulted in very little post-processing contamination.
