World's Largest Clean Room FIBC Manufacturer. Flexituff's commitment stems less from the mammoth manufacturing facilities it possesses and more from our 7000 strong work force. Nothing defines Flexituff better than its people. Young in outlook and rich in experience, Team Flexituff strives for total customer satisfaction, continuous improvement in quality and delivering ever larger value to its buyers. Despite the over arching team spirit that prevails at Flexituff, we believe, commitment to customers begins with the individual. Although, our team works like a well greased machine, it is the individuals – the cogs, who fuel its driving commitment to quality and responsiveness.
