Sibo's extraordinary tube cap offers a number of benefits to companies seeking a better solution to top their flexible tube packaging concepts. Both the cap itself (item PO50F/20, made of PP) and the joining shoulder (item PO50/01, made of HDPE) are extremely thin and lightweight without sacrificing sturdiness. Consumers can use them over and over in the home without fail, and the lighter design helps companies satisfy ever more stringent sustainability requirements.
