We wanted to create a durable lifting container which was solvent-tolerant, rust resistant and had low noise during operation and emptying. The solution was using HDPE-plastics as the lifting container material. HDPE has a high strength-to-density ratio (allowing thinner walls), is corrosion resistant, and is resistant to many solvents as well. Fully Underground systems use less durable materials, which can give worse performance over time. There is also a comprehensive range of MolokDomino lifting containers, which can be combined with lifting bags as well.
