The requalification of our thermosealing process showed a non conformity on our sealings.After further investigation, the tyvek batch used in theses sealings has been found non conformant because the seal width is smaller than expected.The evaluation of the non-conformity showed that this batch has been used in product packaging distributed in the us.This defect is not affecting the sterile state of the product since the integrity testing according to astm f 1929 has been found conform.For the first test, 9 products were found non conformant by the laboratory rescoll finding that the seal width was 3 to 5.5mm on those 9 products whereas it is required at least 6 mm.The second test realized in the same laboratory was conform on all 27 products tested demonstrating that the packaging remains sealed.Fda safety report id# (b)(4).
