Bag for the transport and storage of bulk goods and method of producing such a bag

A bag for the transport and storage of bulk goods comprising a main body including at least a bottom part and four sides connected in pairs along adjacent edges to form vertical ridges at four corners of the bag,

• wherein the bag further comprises four lifting straps, each comprising first and second end sections and an intermediate section rising above a top surface of the main body of the bag,
• wherein the lifting straps are interconnected in pairs by two sleeves to form tubings or ducts extending longitudinally along the top surface of the main body of the bag to allow lifting of the bag by means of a forklift,
• wherein terminal ends the sleeves are connected to the main body of the bag via the lifting straps,
• wherein a longitudinal length of each sleeve, between the terminal ends, is not attached to the main body of the bag to form a longitudinal spacing between the sleeves and the main body,
• wherein the first and second end sections of each lifting strap are secured to corresponding sides of the bag,
• wherein the intermediate section of each lifting strap is reinforced to force the intermediate section into an essentially upright configuration rising above the top surface of the main body of the bag when no load is applied onto a top portion of the bag,
• and wherein the intermediate section is reinforced by means of a flexible reinforcement tube surrounding the intermediate section.
