AMEEN ENTERPRISES- SINCE 1985- EVERYTHING IN PACKING MATERIALS AND TOOLS- BANGALORE DUCT TAPES Duct tape has now become multipurpose and is used for general sealing, patching holes, packing boxes and repairs. Some duct tape can also stick to rough and uneven indoor and outdoor surfaces such as wood, stone, plaster, brick and metal. Well known for its versatility and strength, duct tape is a cloth tape coated with a polyethylene resin on one side and an aggressive, rubber-based adhesive on the other. Unlike other tapes, the fabric backing gives duct tape strength, yet allows it to be easily torn and adhered to a variety of surfaces. Duct tape is constructed with a polyethylene (PE) cloth backing, a material that makes the tape waterproof.
