Bandera designs and manufactures complete extrusion lines.
The gained experience and new technical and commercial organization allow to transmit the innovative know-how to final users-customers with a high degree of process efficiency. Bandera has always developed innovative ideas which very often have contributed to a concrete evolution of the plastic material processing industry.
Bandera designs and manufactures complete extrusion lines for the blown film production, foils and sheets and for pipe production: we have gained a extrusion process specialization that determines the choice of technologically innovative solutions at competitive investment levels through an industrial process with certified quality.
Bandera supplies extrusion units and complete lines for thermoplastic resin coating of medium/large diameter steel pipes. Bandera supplies single-screw extruders (with screw diameters over 380 mm) and co-rotating and counter-rotating twin-screw extruders (with screw diameters over 220 mm).
Costruzioni Meccaniche Luigi Bandera is recognized as market leader in design and manufacture of blown film machines (single layer film and multi layer film) for the production of finished technical packaging film, for application in food and medical-pharmacological fields, agrifilm, biodegradable film and thick film for the production of geomembranes intended for civil and industrial waterproofing systems.
Bandera innovative know-how and technologies are applied to cutting edge thermoplastic process for the production of HDBs, shoppers, and bags of different shapes and sizes, as well as shrink film, pallet wrapping and stretch hood. Bandera technology has focussed on polymer treatment at the hot molten stage through extrusion head with shear rate and temperature control specifically intended for the production of film featuring minimized thickness tolerances and optimized optical/mechanical characteristics. Bandera blown film extrusion lines are equipped with automatic quality control systems, such as loss-in-weight gravimetric dosing system, in-line film thickness measurement, automatic winding, supervisory system and user-friendly computerised line control. Costruzioni Meccaniche Luigi Bandera blown film extrusion range includes:
Techno Flex plus blown film machines for the production of multi layer film (3, 5, 7 and 9 layer). Techno flex plus blown film machines are mainly used in the flexible packaging industry, converting industry and lamination industry. HDB Flex blown film machines for the production of industrial bags HYBRID Flex blown film machines for the production of plastic bags and industrial application Smartflex® plus blown film machines are characterized by a competitive investment level, high productivity, enlarged thickness range, maximized flexibility for different applications/recipes, maximized efficiency, high power consumption reduction, functional and compact layout featuring frames modularity Blown Film machines for the production of agricultural film Blown Film machines for the production of geomembrane hdpe
Product category: Extrusion lines for flat film and sheets
Foil Extrusion Lines
Bandera manufactures complete extrusion lines for the production of high thickness windable single and multilayer foil and production of thick sheet.
Innovative know-how and technologies are applied to cutting edge thermoplastic processin the following applications :120 micron ÷ 2mm thickness windable foil from HIPS, PP, CRPS, A/CPET, PETG and PLA, for rigid thermoformed food packaging applications
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. Furthermore, Bandera innovatively developedthe 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
Bandera designs and manufactures standard and special single screw extruders, counter rotating extruders, twin screw extruders and co-rotating twin-screw extruders, mainly for blown film extrusion, foil extrusion and sheet extrusion, pipes extrusion, and for any other possible application in plastics.
Standard production range includes 55mm, 70mm, 85mm, 105mm, 135mm and 170mm diameter sizes in 18 L/D, 34 L/D, 42 L/D and 52 L/D versions, with output capacity between 300 and 3500 kg/h, depending on the specific features of the process materials. Bandera is the only Italian manufacturer with own in-house manufacturing capacities and relevant quality check of extrusion screws, extrusion barrels and extrusion heads. Extrusion screws consist of splined shafts with a number of conveying and mixing modular sections, made from tempered wear-resistant steel. Extrusion barrels are offered in nitrided steel or with interchangeable sections made from wear-resistant material. The design of special and customized screw profile maximizes process performances in combined applications of extrusion technology and a certified process and the employ of cutting edge machinery and software guarantee an excellent quality level.
Bandera started the operations in 1947 founded by Luigi Bandera and soon proved to be an energetically expanding enterprise playing a pioneering role in the development of the plastic processing machinery Industry. In 1950 turned into a joint stock company. Within 1960 and 1970 the activities expanded to an industrial production scale, thanks to a wide and diversified production range in the extrusion process (PIPES, PROFILES, SHEETS). The Company headquarters are situated in the city of Busto Arsizio (VA), 10 minutes by car close to the new Milan Malpensa International Airport. The factories have been renewed recently to better combine the serial manufacturing phases with relevant quality control procedures. Bandera designs and manufactures complete extrusion lines. The gained experience and new technical and commercial organization allow to transmit the innovative know-how to final users-customers with a high degree of process efficiency. Bandera has always developed innovative ideas which very often have contributed to a concrete evolution of the plastic material processing industry.
