Aluminum coil with polycraft paper is very popular in recent years. Why is there a layer of kraft paper on the surface of aluminum coil? The anticorrosive performance of the aluminum coil itself is superior, and the service life of the aluminum coil is greatly enhanced after being laminated with a layer of kraft paper. Another aluminum jacketing coil is polysurlyn laminated aluminum coil.
Aluminum metal Jacket with polykraft moisture barrier has a certain adsorption effect on the moisture inside the pipeline, which is mainly used for insulation and anti-corrosive projects. Our aluminum coil with kraft paper has been exported to many countries, especially Middle East countries.
We have comprehensive range of thickness and length. It can be cut into different lengths according to your requirements, such as 20 meters, 30 meters, 50 meters,etc., saving your time in engineering.
