Full-Automatic Bagging Machine for Aluminum Profile and Stainless Steel Pipe

Executive summary Our automatic bagging machine forms a film envelope around each profile or tube, then heat-seals and cuts it. It handles tubes of 9.5–50 mm OD and 6,000 mm long at about 10–50 m/min. We size it from your tube sizes, bundle shape and output per shift.

How bagging works

The entrance conveyor feeds the profiles continuously into the bagging station. Film is fed automatically and formed into an envelope with the profile inside it. The machine then heat-seals and cuts the film between pieces, and the outlet conveyor carries each bagged piece to discharge.

The result is a sealed bag around the profile rather than a spiral wrap, so the surface is fully enclosed. In our video, the sealed envelope carries a stainless steel bundle out of the bagging station on the outlet conveyor.

Does the tube fit?

Parameter Bagging machine
Tube size OD 9.5–50 mm
Tube length 6,000 mm as listed, other lengths confirmed in proposal
Bagging speed about 10–50 m/min
Bag size adjustable for different tube OD

Illustrative example: a 25 mm stainless tube, 6,000 mm long, is within the listed tube window. For profile bundles, we confirm the bag size on your bundle drawing.

Bagging speed and output

Illustrative example for 6,000 mm pieces, film travel only:

Bagging speed Time per piece Pieces per hour
50 m/min 7.2 s 500
10 m/min 36 s 100

These figures exclude feeding gaps and film roll changes. Feeding and the outlet conveyor are automatic, so the real limit is often how fast profiles arrive from upstream.

Film and sealing

Item Detail
Film BOPP or PE
Film roll OD 100–200 mm, core 75 mm
Film thickness 30–60 micron
Sealing constant temperature heat sealing and cutting
Temperature control precise, for sealing

Sealing is smokeless and leaves no packing material residue. Changing the film roll is easy, and we confirm the roll size against your output.

Controls and changeovers

Item Detail
Control PLC program, English menu
Modes manual and automatic
Speed adjusted by inverters
Packing action time adjustable for different packing purposes
Bag sealing automatic

For a new tube OD, the bag size is adjusted to the new diameter, and the packing action time is set to suit.

Utilities and safety

Utility Bagging machine
Power supply 380 V, 3 phase, 60 Hz
Air supply 5–7 bar

Sensors and mechanical limit stoppers provide safety, and motors have over-current protection. 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 bagging machine

  • Tube or profile sizes and lengths.
  • Single pieces or bundles.
  • BOPP or PE film, and thickness.
  • Pieces per hour needed.
  • Upstream feeding and discharge layout.
  • Compressed air at 5–7 bar.

Engineering FAQ

Q: What tube sizes does the bagging machine take? A: OD 9.5–50 mm, 6,000 mm long, with the bag size adjustable for different OD.

Q: How fast does it bag? A: About 10–50 m/min, or 7.2–36 s for a 6,000 mm piece.

Q: Which films can we use? A: BOPP or PE, 30–60 micron.

Q: Does sealing leave smoke or residue? A: No. Sealing is smokeless and leaves no material residue.

Q: What utilities does it need? A: 380 V, 3 phase, 60 Hz power and 5–7 bar air.

Next step

We plan your bagging machine in three steps:

  1. Submit your layout drawing with tube sizes, lengths and pieces per hour to info@fhopepack.com.
  2. Receive a proposal within 48 hours, with the machine, film and layout.
  3. Book a site survey to fit the machine to your line.
