DSM Minera iodine derivatives used to be packed in 20- and 40-litre fibre drums. Now they are packed in an easy-to-recycle one-material pack that is air- and watertight and has an easy opening and closing system made by CurTec. The UN-approved 20-litre Click Pack has a dark blue body and lid that sports the company identity. It offers sufficient protection against light and a red tamper evident pin with a DSM embossing provides security.
