BAG Column Formers

BAG® Column Formers are a single use formwork system that gives an excellent smooth fair face surface finish. Our Column Formers are manufactured by welding together several layers of high quality polyethylene coated craft paper, that are spirally wound and bonded together by heating the polyethylene. Once this step is complete, a water resistant foil is also spirally wound over the craft paper, sealing the column against humidity. This manufacturing process requires no additional adhesives which reduces the wall thickness, making the BAG® Column Formers light and easy to handle.
