This new design meets the highest requirements of medical device manufacturers, giving wide peelable film-to-film window for opening and removing the content as well as strong bottom seal to prevent broken seals during packing and transportation. Dupont ^TM uncoated Tyvek^® used as breathable part gives faster air removal and there is no contamination risk from loose particles of coating.
