Three Layer Bubble Film Machine (3 Screw Extruder)

3 layer bubble film extruder primarily consists of an extruding system, a forming system, a winding system and an electric control system. Raw materials such as LDPE, LLPDE,HDPE,PP and recycled materials are first extruded by main extruding system at very high temperature to produce bubble films. Next these bubble films are added an additional PE film by the secondary extruding system. Bubble are formed by bubble roller and water cooling for faster and higher-quality film production.
The PLC can control and monitors the machine and temperature.

The bubble film making machine is equipped with automatic cutting,automatic winding，meter counting alarming, and cutting functions, which make it highly efficient.
This machine comes with many selectable parts, such as in-line film edge trim winder, bubble film perforator, and hydraulic screen changer.
3 extreders：Compared to 2 screw extruder, thickness of bubble layer and base layer can be controlled separately thus saving material cost. Various formulas can be used to produce bubble films of various colors. This machine features a very steady operation.

3 layer bubble film is an impact-resistant, moisture-proof and shockproof chemical product suitable for packing, which is non-toxic, tasteless and has a very nice shock absorption ability, impact resistance, heat resistance, moisture resistance, corrosion resistance, transparency and so on.
