If a problem comes up months later, this record makes it much easier to see whether it was the glass, the closure or the filling method. See also our checklist on DIN18 parts compatibility and our overview of GuardSeal plugs<\/a>, which covers the other plug styles we supply.<\/p>\n If you are switching bottle supplier, changing formula, or moving from hand filling to a machine, order samples and run the steps above before placing a carton order. It costs little and avoids pallets of unusable stock.<\/p>\n No. The sets described here use a non-tamper-evident PP cap. If you need tamper evidence, add an outer seal or choose a different closure type.<\/p>\n Only if the necks are the same DIN18 finish and a fit test passes. Always test with the exact bottle you intend to fill.<\/p>\n At minimum 24 hours in upright, inverted and side positions, using your actual formula. For long shelf-life products, add a longer stability test of your own.<\/p>\n Choose the color that suits your label and brand. The function is the same, so black and white caps can be tested together as one family.<\/p>\n![\"Row](\"https:\/\/www.packaging.si\/wp-content\/uploads\/2026\/11\/row-of-amber-glass-bottles-ready-for-filling-and-closure-testing-1024x682.jpg\")
