Performance and use

7 layer Air bubble film machine main consist of number 1 main extruder(doule screw), secondary extruder(single screw), number 2 main extruder(double screw),forming unit,composite film lamination unit(2 sets), winding unit and electronic control system.5 extruders produce 5 layer bubble films, in the meantime, composite materials such as aluminum foil, Kraft paper, EPE foam can also be added.
7 layer air bubble insulation foil, 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.
