Bimodal Clear Heavy Duty. Suitable to hold 15kg. 30” x 45” x 54” (762 x 1143 x 1372mm). A bimodal sack is manufactured from a polymer that is at a molecular level stronger due to the structure of the raw material. Bimodal sacks are lighter in weight whilst retaining the strength. Smaller boxes reduce the amount of packaging used, thus reducing the carbon footprint.
