Described are liners for bulk containers that are abuse resistant. The liners include at least one sidewall. The sidewall includes at least an exterior ply and an interior ply. Optionally, the sidewall may include at least one intermediate ply. One of the plies includes a first polyolefin-silicone copolymer. The adhesion between the plies is from 0 g/2.54 cm to 50 g/2.54 cm (0 g/in to 50 g/in).

A device for storing and transporting a bulk material, in particular a pharmaceutical bulk material, comprising a base container and at least one connection body detachably connectable with the base container, wherein the base container and the connection body in the connected state form a sealing section with which the base container and the connection body are connectable or are connected gas-tight with one another. A method for filling such device with this bulk material and for emptying a device filled with this bulk material as well as the use of such device for storing and transporting a pharmaceutical bulk material.

A stitchless highly oriented polypropylene fabric bulk bag of the type that can hold 500 to 5000 pounds (226.7 to 2268 kilograms) of bulk material includes a highly oriented polypropylene fabric top, body and bottom, with a heat fused joint providing an air tight connection between the top and body, and another air tight heat fused joint connecting the body and bottom. A fill spout and discharge tube may also be provided with an air tight heat fused joint connecting the fill spout to the top and another air tight heat fused joint connecting the discharge spout to the bottom. Heat sealing machinery include heat seal bar assemblies that can self-align during heat-sealing to apply even pressure to all areas being heat sealed. A heating element is of single piece construction and can include end coupler portions as part of the single piece construction. Carrier plates used in a heat-sealing assembly line guide parts placement, provide quality checks for parts placement, and tooling set-up for machinery.
