摘要： Described are liners for bulk containers such as intermediate bulk containers (IBC) that are abuse-resistant and barrier-providing. The liners are recyclable. The liners have at least one sidewall that is multi-plied and the plies are multi-layered. The liners are preferably metal-free and nylon-free. An outer ply comprises at least one discrete polypropylene-based film layer. Addition of polypropylene α-olefin to sealant and/or polypropylene-based film layers also improves performance. Methods of making and using the liners are also provided.
