Described are liners for bulk containers such as intermediate bulk containers (IBC) that are abuse-resistant and barrier-providing. The liners have at least one sidewall that is multi-plied and the plies are multi-layered. The liners are preferably metal-free. Each ply independently comprises at least three layers that comprise: a first layer and a third layer each comprising a linear low density polyethylene (LLDPE) or a very low density polyethylene (VLDPE); and a second layer between the first and third layers and comprising a thermoplastic oxygen barrier of ethylene-vinyl alcohol copolymer (EVOH) and a thermoplastic elastomer (TPE). A ply may further comprise a fourth layer and a fifth layer, each comprising a polyamide, the fourth layer being located between the first and second layers and the fifth layer being located between the second and third layers. Methods of making and using the liners are also provided.
