Abstract
A pallet container includes a bottom pallet, a lattice frame, and a multilayer inner container made of thermoplastic material by a blow-molding technique and received in the lattice frame, for storing and transporting liquid fill material. The inner container has an exterior layer which is configured to be incapable of permanently retaining an electrostatic charge by allowing electric charges to be drained. The exterior layer contains an antistatic compound and has a layer thickness which does not or only insubstantially change a transparency or translucency of the exterior layer, allowing easy optical detection of a fill level of the liquid fill material in the container. The exterior layer includes a fusible, easily stretchable thermoplastic material (polymer). At least one of a center layer and an interior layer of the multilayer container includes a cold-impact-resistant HDPE material (High Density Polyethylene) with a high molecular weight.
