The top layer is weather resistant and in the best duct tapes, it is also resistant to other elements such as heat, chemicals, and oil. The middle layer is a fabric layer that provides strength and the fibers that improving its tearing ability. The bottom layer is the adhesive layer that allows it to stick to a host of different surfaces. The weight and thickness of duct tape are due to its multiple layers. If it is a similar weight, then it is unlikely that these layers are either missing or substandard, meaning it is unlikely to be strong enough for its intended purposes. The same goes for weight duct tape should be heavier than masking tape, electrical tape, or sellotape. Similarly, if once you tear the tape it begins to curl at the ends, this is a clear indication that it is too thin. If you struggle to find the edge of the tape, then chances are it is a poor-quality tape. High-quality duct tape is thick, it should be visibly thicker than other forms of tape such as sellotape, masking tape, and electrical tape. While it should stretch a little, excessive stretching reduces its effectiveness and its strength. If you need scissors to cut the tape from the roll, there is an increased likelihood that the tape will stretch once it is placed under any stress. The fibers in duct tape are designed to work this way. While you want your duct tape to hold fast once it is in place, you also want it to tear off easily from the rest of the roll. But, how do you know you are buying the right duct tape for your needs? Here are the key elements to look for in good duct tape.

From its humble beginnings, duct tape soon became a staple in every store and every home in the US and across much of the world. Originally it was used to keep moisture out of ammunition cases, but it was not long before military personnel discovered that it could be used to fix almost anything from aircraft to jeeps, and even guns, After the war the tape become an essential element in the housing industry, being used to connect air conditioning and heating ducts. Duct tape was first manufactured in 1942 for military uses.
