30 mm MTO LUG from Ajanta Bottle, Our most popular glass bottle cap, the red metal closure, keeps products sealed in glass bottles, assuring their safety and quality. Even when the product or liquid is shaken upside down, these caps and closures provide a perfect, leak-proof seal. We also provide customising options for these closures. Brand names and logos printed on glass container lids help consumers recognise brands and improve brand value. These gorgeous coloured closures improve the beauty of our food-grade and FSSC 22000 certified glass bottles.
