Main features

  • Max. width of the pack depends on its height
  • Polyester infeed-outfeed conveyor belt with high friction coefficient. Product centring guide.
  • Sealing bar with cutting blade actuated by a pneumatic cylinder (no type of emission during the sealing stage)
  • Height of work surface: 850 +/-25mm
  • The temperature of the sealing bar and the tunnel is controlled with PID thermostats
  • Safety photocell that blocks the sealing blade if it detects an obstacle in its path
  • Automatic upper and lower system to unwind the film reel with dragging rollers
  • Max diameter of the heat-shrinking film reel 350 mm – thickness between 35 and 100 microns
  • Heat-shrinking tunnel insulated with rock wool and heated with resistors. Forced ventilation system with air circulation.
  • Conveyor belt of the heat-shrinking tunnel in thin steel mesh with a speed adjustable gear motor
  • Machine with a Siemens S7 PLC and TP 177 Operator panel
  • Voltage supply: optional choice between 3-phase 220V & 3-phase 400V+ Neutral
  • Air consumption: 100 NL/min for simple models 200 NL/min for fast models. Compressed air required 6 bar
  • Switch to exclude all other machine operations and use it as a conveyor belt
  • Switch for the machine use cycle change in automatic, manual/semi-automatic mode with pedal-start

Optional features

  • Guides for product containment after the sealing bar
  • Side guides to protect the product installed inside the tunnel
  • additional 400 mm of insulated hood positioned at the outfeed of the heat-shrinking tunnel
  • Photocells at the tunnel outfeed to accumulate packs and prevent them from being blocked inside the tunnel
  • Self-sizing mechanical presser on the pack for unstable products
  • Film presser rollers
  • Electric winch to lift the upper film reel
  • Pneumatically lifted dragging film roller to facilitate reel change operations
  • Machine mounted on wheels
  • Section of the conveyor with thick rollers positioned below the pack cooling unit at the outfeed of the heat-shrinking tunnel. This station is ideal to group products which are only packed with film
  • Sealing bar height set automatically
