Complete extrusion lines for the production of high thickness windable foil and sheet

Bandera manufactures complete extrusion lines for single and multi layer foil, mainly intended for food packaging and for the production of high-thick sheet for industrial thermoforming

Innovative know-how and technologies applied to cutting edge thermoplastics processing in the following applications:

• 120micron ÷ 2mm thickness windable foil from HIPS, PP, CRPS, A/CPET, and PETG (compact or foamed), PLA, for rigid thermoformed food packaging applications (in-line or external thermoforming)
• Thin PP and PET sheet (embossed, as a standard) intended for paper and cardboard industry
• Mid-thick sheet from PS and ABS/ABS-PMMA intended for household appliances 
• Mixed material sheet (thermoplastic rubbers and non-homogeneous industrial waste as well) for vehicle components and deep draw thermoforming
• Technical sheet from HDPE, PP, HMWPE, PC mixed with ABS 
• Flexible sheet intended for waterproofing applications (multilayer PP/PE geomembranes) with internal fibre reinforcement and outer nonwoven fabrics, which are in-calander coupled 
• High transparency and optical quality sheet from PET, PC, and PMMA
• High opalescent sheet from PMMA/ABS intended for panels and movable edges (thin and windable)

Bandera is world leader in extrusion technology intended for high rate outputs (up to and over 2,500kg/h), thickness and width range (0.12 – 2mm up to and over 2,400mm width) for the production of PET foil. Bandera extrusion lines do not require any material pre-treatment as they are based on a patented composite extrusion system (co-rotating twin-screw extruder with enhanced multiple high vacuum venting system).

Furthermore, Bandera innovatively developed in the following processes:

• Bulk dosing systems for master batches and mineral fillers for composite sheet by co-rotating twin-screw and/or cascade extruders combined with innovative and precise raw material gravimetric loss-in-weight dosing units
• Fully automated multi-reel winding systems for high-speed foil extrusion lines
• Melt super filtration systems

Line control is via computerised supervisory systems aimed at in-line final product quality control.
