Det prim\u00e6re form\u00e5l med testning af farvestofindtr\u00e6ngen er at sikre, at emballagen bevarer sin integritet, forhindrer kontaminering og sikrer produktsikkerhed i hele dens holdbarhed.<\/p>\n\n\n\n<p>Denne metode er is\u00e6r kritisk for sterile produkter, hvor selv det mindste brud p\u00e5 emballagen kan kompromittere produktkvalitet og patientsikkerhed.
