Description:

Double-Layer Co-Extrusion Stretch Film Making Machine 1. Diameterof Screw Stem: 55mm*2 2. L/D Ration of Screw: 28:1 3. CEDouble-LayerCo-Extrusion Stretch Film Making Machine 1. General Introduction:Thismachine is designed to produce stretch film(cling film) forindustry or food packing, which is composed of eight parts – gluefeeding part, 1st extruder part, 2nd extruder part, filter part,Die-head part, traction part, winding part and side film trimmingpart. Thismachine uses LDPE and LLDPE as main materials to produce stretchwrapping film ( could produce one-side sticky film and the otherside normal ), Adopting double screws and double two hoppers. Thisco-extrusion stretch film is widely used in packing area forarchitecture, auto parts, hardware parts, etc.  2. Characteristics:1) Screwand cylinder are all made of 38 CrMoALA after nitrogen treatment,which has an advantage of corrosion resistance and endurance,etc.2) Thecooling device adopts cycle water cooling which provide the besttransparent effect of the stretch film.3) Rewinderadopts with friction-rewinding-type, with cutter device for edgecorrecting  3.
