Automatic Profile and Panel Bagging and Shrinking Line

Executive summary Our profile and panel shrinking line wraps long products in shrink film, seals them along the length and shrinks the film in a tunnel. A longitudinal side knife makes product length unlimited. The machine choice depends on the cross-section: our side sealer takes products with width + height between 400 and 900 mm, while our profile shrink line takes narrower sections up to 450 mm wide and 150 mm high.

How the line works

In this installation, our line packs long flat panels and profiles in three stages:

  1. Bag and seal. The product runs on a belt conveyor into the sealer. Film wraps around it, the side knife seals the length and the cross knife seals the ends.
  2. Shrink. A roller conveyor carries the sealed pack through the heat shrink tunnel, where the film tightens onto the product.
  3. Unload. At the end of the line, operators stack the finished boards.

The sealer has a warning label at the knife: keep hands out of the cutter. The seal knives are heated and must be guarded in operation.

Choosing the machine by cross-section

Length is not the limit, because the side knife seals continuously. The cross-section decides which machine fits:

Machine Cross-section window Length
Side sealer MO-900 400 mm < width + height < 900 mm, sealing height 300 mm over 250 mm, not limited
Profile shrink line width under 450 mm, height under 150 mm not limited

Two examples, both illustrative:

  • Panel 600 mm wide and 50 mm thick: width + height = 650 mm. This is inside the side sealer window.
  • Profile bundle 200 mm wide and 100 mm high: width + height = 300 mm. This is below the side sealer window, but fits the profile shrink line.

We check your largest and smallest sections against these windows before we fix the machine.

Line speed for long products

On the profile line, the tunnel conveyor (0–10 m/min) is slower than the sealer (20 m/min). So the tunnel sets the output. A quick upper bound:

  1. Tunnel speed. At the full 10 m/min, 10 m of product passes per minute.
  2. Pieces per hour. For 6 m profiles, 60 × 10 ÷ 6 = 100 pieces per hour.
  3. Real output. This figure is a ceiling, not a rating. Each piece needs a gap for the cross seal, and the film may need a slower tunnel speed to shrink well, so real output is lower. We confirm the tunnel speed on your film and product in a trial.

Film and sealing

  • Side knife. A constant-temperature side knife seals the length. It works continuously, so product length is not limited.
  • Cross knife. The cross knife moves vertically to seal the front and rear ends. The seal line is straight and strong.
  • Film length. An electric eye and timer set the film feed length. Horizontal and vertical electric eyes also detect thin or small products.
  • Scrap. The film edge trim is taken up automatically by a separate motor.
  • Adjustment. Changing pack size only needs a hand wheel.

The side sealer uses a Siemens colour touch screen with PLC and an Omron temperature controller. The seal bars are permanently heated and coated with Teflon.

Utilities and safety

Utility Side sealer MO-900 Profile shrink line
Power supply 380 V, 50–60 Hz, 3 phase confirmed in proposal
Air 0.5 MPa (5 bar) 6.0–8.0 kg/cm²

The shrink tunnel is the main power load, up to 28 kW on the side sealer line, so check the supply at the line before installation. The standards that apply depend on the destination market. For CE markets, ISO 12100 sets the risk-assessment method and EN 415-10 sets general requirements for packaging machines.

Selection checklist for a profile and panel shrink line

  • Largest and smallest cross-section (width and height).
  • Shortest and longest product length.
  • Film type: PE or POF.
  • Pieces per hour and the tunnel speed this needs.
  • Infeed and outfeed conveyors, and stacking at the end.
  • Electrical supply for the shrink tunnel, and compressed air.

Engineering FAQ

Q: Is product length limited? A: No. The side knife seals continuously, so length is not limited. On the side sealer, the minimum length is 250 mm.

Q: Which machine fits a 600 mm wide, 50 mm thick panel? A: The side sealer. Width + height is 650 mm, inside its 400–900 mm window.

Q: How do you change between pack sizes? A: On the side sealer, only a hand wheel is needed to adjust for a new pack size. The electric eye and timer then set the film length for each piece.

Q: What limits the output on long profiles? A: The tunnel conveyor. At 10 m/min, 6 m profiles give at most 100 pieces per hour before gaps.

Q: How much power does the shrink tunnel need? A: Up to 28 kW on the side sealer line, plus 2.5 kW for the sealer.

Next step

We size your shrink line in three steps:
