High strength blown film
The achievement will be transformed by self investment and will be successfully transformed in 2021. In this achievement, the tubular film extruded by the blow molding die is rotated to make the tubular film spiral in the process of traveling, and then the front half and back half of the tubular film are hot pressed to form an interlaced network structure, greatly increasing the longitudinal and transverse strength of the co extruded film formed by blow molding.
