- Product Details
- Company Profile
Details： Reversing haul-off with ±360°horizontal turner bar system， with stable reversing， consistent linear speed， reasonable and scientific structure ensure saving energy and easy operating. By means of the reversing haul-off unit，the structure of die head is simplified by replacing rotating die head The reversing haul-off unit resolves many problems of long channel for dwelling in the rotating die head， difficult sealing for the melt， easy leakage， unsymmetrical heating， difficult maintenance， big film thickness tolerance and so on. The haul-off unit reduces the difficulty for recipe of the multi-layer coextrusion product and production technical processing control. If using IBC (Internal Bubble Cooling system)， the blown film line can produce film with higher transparency and better performance. The produced film is very flata， and in high-quality by using of reversing haul-off unit， which can meet demanding for hagh precision and high-speed printing.
