Description

7 layer bubble film extruder is primarily comprised of a number 1 main extruder, a secondary extruder, a number 2 main extruder, 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. Compared to single screw extruder machines, twin screw extruder machines makes it possible to control the thickness of bubble layer and base layer separately thus having a better composite effect.

Application
7 layer 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% of 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 better prevents heat from escaping, thus realizing a better thermal insulation effect.

Features
1. This bubble film machine has very high production capacity, with a maximum speed of 50 meters per minute.
2. This bubble film extruder has very good quality. Ztech's forming cylinder mold is designed with an up-to-date vacuum system, with special steel sheets to prevent wearing, and with a dual pipe cooling system to realize better and more even cooling effect. Ztech's unique T-die design is of vital importance to producing high quality bubble films. Precise T-die materials makes products even in thickness, realizing an easier operation flow and prevents glue leakage. Ztech's screw design makes recycled materials 100% usable, ensuring that bubble are even in thickness and better in quality.
3. The bubble wrap machine comes with a strict safety system. Emergency stop button can stop the entire machine, including circuits, extruders and cylinder of roller. Protective barriers are installed on all important parts, all actions halt automatically to prevent damage whenever protective barriers are opened.
4. This extruder has very good composite effect. Up-to-date technology ensures that its composite effect stands out.
