Problems solved by technology

Traditional bulk bags which have not been designed for pushing and pulling can only be transported by hanging them from hook straps located at the top of the bag.

Bulk bags of the type referred to above have the disadvantage that, in particular, the lower surface may be damaged during transportation of the bag, particularly if the bag is pulled or pushed over a surface.

Even minor obstructions such as small stones or the like can cause damage such as cuts to the surface of the bag, thereby allowing some or all of the contents to escape prior to the desired discharge time.

Transportation of the bags may also be difficult, requiring either pushing or pulling the bag along a surface in many cases or, alternatively, placing the bag on an alternative support such as a pallet.
