Twin Bubble wrap film machine
TORNINOVA
AIR BUBBLE FILM EXTRUSION LINES
The Twin Bubble wrap film machine allow to produce in-line, in a single step, an air bubble film for insulation applications composed of: two layer of air bubble film laminated with coated aluminium foil on the external side.
This used machine can produce, of course, air bubble film in 2 or 5 layers for the packaging market.
TWIN BUBBLE wrap film used machine
Torninova, in-line mono extruder for reflective insulation materials
The Twin Bubble uses LDPE pellets to produce multi-layer compound (sandwich) bubble foil, PE-foam and aluminum foil, all in a single process. The system basically consists of two "twin" bubble lines producing two bubble foils (laminated with coated aluminum film) in opposite directions; in the middle there is a lamination station that welds the components together. The final multilayer product is then collected on the winder at the end of the line.
The Twin Bubble system has the following characteristics:
- Two extruder for the production, at the same time, of the two layers of air bubble film and one, placed in the middle, for their lamination.
- Two interchangeable forming cylinders Rewinder with automatic cycle that allow to produce rolls from 25 up to 150 mt and more.
- Possibility to add two additional lamination unit by hot air in order to laminate a layer of foam in the centre of the material (between the two layers of air bubble film).
