摘要： There is described a bag for being manipulated by a lifting element, including a tube portion defined by at least two opposed side walls and two opposed end sections. The first end section closes the tube portion for defining a cavity and the second end section includes at least one flap extending from one of the side walls to be connected to the other side wall. There is a slot defined beneath and parallel to the flap in between the opposed side walls for receiving the lifting element, the flap and the slot thereby defining a handle. There is also one or more reinforcement members, such as a strip of HDPE or the like, each applied to and extending between the flap and the corresponding side wall. The reinforcement strip resists tearing of the handle when the bag is lifted.

摘要： The present invention pertains to a multilayer bag for receiving a powder material. A tubular wall is provided to have, once the bag is filled with the powder material and stacked, stacking sections which face upward and downward and side sections which face laterally. The tubular wall has an inner plastic liner with vents along at least one of the side sections to allow stacking pressure to expel air through the vents. There is also a first paper layer contiguous with the inner plastic liner, then a humidity barrier layer non-adjacent with the inner plastic liner; and at least one outer paper layer. The placement of the vents and the non-adjacent humidity barrier facilitate expulsion of air via the vents during and after stacking and avoid inadvertent sealing melt bonding between the humidity barrier and the inner liner.
