NovaStar, BL153, 3-Layer Air Bubble Film Making Machine, 1600mm Width, Two Screws (New)

Description

  1. Machine Introduction
    1. Highly automatic air bubble film making machine that can produce 3-layer and 2-layer air bubble film rolls with maximum width of 1600 mm finished bubble film roll.
    2. All mechanical parts, especially key parts including the forming rollers and molds, are precisely manufactured, the quality strictly being controlled, which ensure even thickness and smoothness of bubble film.
    3. Produces superior quality air bubble films. Our machine can produce 2 layers air bubble film at 25 gsm while bubble still has enough strength.

  4. Optional Parts for Upgrades
    1. Extra cost for upgrading main extruder size from Φ80×32 to Φ85×34: to increase the maximum capacity from 130 to 140 kg/hr. Upgraded main extruder
    2. Upgrade to double screws design for main extruder (Φ75×32 Φ75×32), sub extruder Φ75×32: increase the maximum capacity from 130 to 160 kg/hr; thickness of each layer can be controlled separately and much easier; suitable for using over 90% lldpe, saving material cost at a higher level. Double screws design
    3. Hydraulic driven filter changer: to quick change the extruder filter; shorten the filter changing time from 30 minutes to 2 to 3 minutes; one set for each screw. Hydraulic driven filter changer
    4. Upgrade with infrared heaters on the t-die and screws: saves electricity up to 30%. Infrared heaters
    5. Add one more forming roller (diameter: 270 mm) with silicon roller and cooling roller.
