7 Layers Aluminum Foil Laminated Air Bubble Film Machine (5 Screw Extruder)

7 layer bubble film extruder is primarily comprised of an extruding system, a forming system, an aluminum composite film lamination rack, a winder and an electronic control system. Primarily, 2 sets of main extruders with twin screws and 1 set of secondary extruder with single screw produce 5 layer bubble films, in the meantime, composite materials such as aluminum foil, Kraft paper, and EPE foam can also be added. This machine comes with many selectable parts including in-line edge trim winder, in-line perforation unit and hydraulic screen changer.
5 extruders：Compared to 3 screw extruder machines, 5 screw extruder machines makes it possible to control the thickness of bubble layer and base layer separately thus having a better composite effect.
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.
7 layers double aluminum foil laminated bubble film, because of its thermal insulation ability, is widely used in many industries including construction industry, luggage industry, refrigeration industry and packaging industry. It can be used as construction material for roads, airfield runaways, culverts and bridges as impact resistant and expansion-proof material. It can also be installed on roofs, walls and floors to block up to 80% heat exchange between the building and environment. In this way, it can protect walls, hold temperature so that it does not drop rapidly. An additional protection layer will better prevent heat from escaping, thus having a better thermal insulation effect.
