Rikutec Group, a leading blow moulding technology specialist, has introduced the industrial packaging industry’s first all-plastic twin drum which meets stringent regulatory demands as specified by the ADR Treaty for safe storage and transport of highly aggressive chemicals.

The blow moulded ‘tank in a tank’, which requires no secondary container, also meets UN-sanctioned approvals in Europe and the US.
Andreas Amberg, President of Rikutec America, said: “Rikutec has developed the highest rated dual-containment drum in the industry. This first all-plastic twin drum is the next generation of industrial packaging which sets a new benchmark for high purity with the lowest metal and particle content while meeting the highest safety standards.”
The 200-litre twin drum effectively stores and transports highly aggressive chemicals in an ultra-clean environment for a range of industrial markets, including the pharmaceutical and semiconductor industries.
A different drum
The unique all-plastic drum delivers numerous advantages over competing metal and plastic-metal drums, including corrosion resistance, high pressure resistance, and 100% recyclability. Another advantage is that the twin drum can be filled and dispensed by using QC-Dip tubes, which prevents any contamination of the contents.
The twin drum successfully withstands the 45-degree ‘on rim’ drop test (three times) from a height of 2.8 metres and absorbs the impact and energy from falls for the highest safety performance for transport. The twin drum is a 320 kPa (46 psi) pressure-rated container for packaging group 1(X) rated high-density materials up to 1.9 kg/dm.
It consists of a two-layer inner drum made of high-purity, totally virgin high-density polyethylene (HDPE) with no additives or stabilisers. The two-layer outer drum is made of UV-stabilised HDPE. The two tanks are inserted together and a hot plate welder joins them together with an HDPE cap.
All three drum structures are manufactured on Rikutec’s patented multilayer coextrusion blow moulding machine in a cleanroom environment at the company’s Westerwald plant in Germany, where Rikutec provides highly-rated engineering expertise and a range of in-house capabilities.
