W&H launches VAREX blown film equipment

W&H introduces VAREX film blowing equipment. The equipment is used for the production of high-quality 5-layer polyolefin composite membranes, which have a production capacity of over 700 kg/hr through a blown film die with a nozzle diameter of only 400 mm. This is due to MULTICOOL seeking a double-layer cooling ring system, which can also achieve the best cooling effect in the hot season, thus creating conditions for the equipment to significantly increase its production capacity.

Its 5-7-layer blown film die MAXICONE has a patented cone-shaped design, because the melt flow path is short, the melt volume is small, thus ensuring that the melt stream residence time is very short, in particular, in the production of difficult The same is true for the barrier layer. MAXICONE blown film die can not only produce barrier film, but also produce polyolefin composite film, and it has high production capacity.

It is very important to ensure the quality of the film and stabilize the air bubbles during production. W&H's VARIOCAGE and NOSTIC AIR CAGE two bubble stabilization baskets are characterized by accurate tape pull and small width errors. The advantage of the patented non-contact bubble stabilization basket NOSTIC AIR CAGE is that it can produce highly viscous, highly sensitive films.
