2020 MARIANI TRM-700 series (including the LF and LF/T variants)

Technical Specifications

              The TRM-700 series (including the LF and LF/T variants) typically features the following technical parameters: 

• Production Speed: Capable of high-volume output up to 60 cycles per minute.
• Product Dimensions:
• Minimum : 60 x 120 x 60 mm (LxWxH).
• Maximum: 320 x 460 x 370 mm (LxWxH).
• Film Requirements: Uses LDPE (polyethylene) with a thickness range of 30 to 90 µm and a reel width range between 225 mm and 575 mm.
• Tray Handling: Can process tray heights from 35 mm to 100 mm depending on the product configuration. 

• Key Performance Features
• Continuous Film Wrapping: The machine operates in a continuous mode, typically using a fly-bar system for wrapping without a traditional sealing bar, which ensures tight, square packs.
• Automation & Control: Managed via a Siemens PLC system with a 12-inch Siemens SIMATIC touch-screen HMI on a rotating/swivelling frame for easy operator access and failure diagnostics.
• Efficiency: Includes features like a low-level film reel loading frame that accommodates two reels at once for faster transitions, and servo-motor driven guiding chains for precision.
• Energy Efficient Tunnel: The integrated shrink tunnel uses high-quality rock wool and polyurethane insulation to ensure maximum heat transfer with minimal energy consumption. 
•  We are currently run 1 litre cartons in 2x4 and 3x4 formats and soon to be running 2x3.
• Power & Utility Requirements
• Electrical: 3x400 V – 50 Hz (or 415V depending on region) with an installed capacity of roughly 75–85 kW.
• Pneumatic: Requires a minimum air supply of 6 bar (clean and dry) with consumption around 100 Nl/min.
