CDS Group, co-operated by Sacmi, with the target to complete its set of closures in ultra-light version, to introduce on the market new carbonated closure. Super II°, even being a one-thread closure (1.50 g for finish Cetie 30-38), was designed to be interchangeably used on those lines where the still version 26.2, 3 starts was already running. This closure has been validated for a CO2 carbonated level of 3.5 vol/l, quietly compatible for carbonated mineral waters and low-medium carbonated soft drinks. This closure was designed with a folded guarantee band since this solution allows an easier passage on the PET neck finish and a reliable grip on the safety ring of bottle mouth. Same deep attention was dedicated to the shape and length of thread, suitable to get a close screwing, thread by thread between closure and bottle mouth, in order to avoid risks of any blow-off effect. Compression technology can face the versatility of injection system, with many plus such as productive and dimensional constancy, lower thermical stress on PEHD material, easier production and energy saving.
