The production of master tape belongs to the middle stream of the industry and is the raw material for the processing of downstream finished products. At present, the domestic tape manufacturers are mainly concentrated in the downstream. The master tape is mainly used in the tape cutting factory to cut into the BOPP sealing tape finished products of different specifications used in daily life according to the demand.
Therefore, tape mother roll is a kind of tape products, and we see in daily life, different from the tape, in life generally can rarely see, the main circulation in industrial production.
The structure of the tape master roll is the same as that of the finished tape, which is based on the BOPP film master roll. After the BOPP film is treated by high voltage corona, the surface of one side is rough. After heating, the water-based pressure sensitive adhesive (the main component is butyl ester) is evenly coated, and the adhesive layer of different thickness is formed according to the customer's requirements.
The difference is that there is no cutting of the tape mother roll, the width and length are much larger than the common tape, the general width is 1270-1280mm, as long as after cutting, to form the general market to see the width of about 50mm small roll tape.
The high quality and high performance duct tape motherroll can maintain stable performance even in extremely harsh climate. The duct tape motherroll has excellent adhesion, initial adhesion, good stickiness, large tensile strength, light weight, cheap price and easy to use.
