Blown Film Machine SH-DF45/55PEW120 (A/B/A)

The SH-DF45/55PEW120(A/B/A) is a high‐capacity, advanced blown-film extrusion line engineered for efficient production of polyethylene (PE) films. With a screw diameter of 45 / 55 mm and a die head size of 120 mm, this machine is designed to handle a variety of materials (HDPE, LDPE, LLDPE) and produce films with excellent consistency, uniform gauge, and high throughput. Available in different layer configurations (A / B / A), it offers flexibility to meet diverse manufacturing needs—from shopping bags and garbage bags to industrial packaging films.

Details

• The model features screw diameters of either 45 mm or 55 mm (“45/55”) and a die head diameter of 120 mm (“PEW120”), which allows for broader film widths and higher output relative to smaller machines.

• Based on comparable machines and industry benchmarks, film widths in this class may reach up to 700-1000 mm (folded width) or more, and film thicknesses for HDPE can be as low as approx. 0.006 mm, while LDPE/LLDPE thicknesses may vary ~0.02–0.15 mm depending on material and conditions.

• The machine is compatible with HDPE, LDPE, LLDPE, and even blended/recycled resins. With the larger die diameter (120 mm) and screw size, it is built for higher throughput—making it ideal for medium to high‐volume film production lines.
