Edda builds orbital stretch wrapping lines, shrink film lines and pallet wrappers for steel tubes, pipes, hollow sections, metal profiles and other long, heavy loads. Bundles travel on heavy-duty roller conveyors through a rotating ring and leave wrapped along their whole length – protected from corrosion, dirt and handling damage, and ready for storage, export or the next customer’s line.
Why long, heavy loads need their own packaging line
Steel tubes and profiles leave the mill or the extrusion press in long, heavy bundles. They are lifted by crane and forklift, stored in open yards and shipped by truck, rail and sea. A tube that arrives rusty, scratched or bent at the end is a claim – and an unwrapped bundle collects moisture, dust and road salt on every leg of the journey.
- Bundles are too long and heavy to wrap safely by hand.
- Moisture and dirt between tubes cause corrosion during storage and sea freight.
- Loose bundles shift and damage tube ends and profile edges in handling.
- Packing must keep pace with cutting, bundling and strapping lines without extra staff.
Which solution for which load?
Choose by the bundle length and weight, the protection you need and where the wrapper sits in your plant.
Heavy Duty Lines
Steel tubes and heavy profiles
Orbital wrapping line with heavy-duty roller conveyors and transfer tables. Ring speed 10–80 rpm, min. 100 × 20 × 1400 mm, unlimited length.
Spinner 2200 S Pallet
Heavy pallets and stacks
Fully automatic end-of-line wrapping with 500 mm film for loads from 700 × 400 × 2000 mm, with no operator at the wrapper.
Shrink Nylon Lines
Profile and pipe bundles
Wraps bundles up to 6000 mm long in 70 micron PE shrink film and bands them, at conveyor speeds up to 30 m/min.
Heavy-Duty Roller Conveyor
Infeed and outfeed
Reinforced roller conveyors that carry steel profiles, tubes and large panels into and out of the wrapping machine.
Robowrap 2700 VPT
Oversized and irregular loads
Battery-powered robot that drives around the load: no limit on pallet size or weight, wrapping height up to 2700 mm.
Wraptor 1650 VPT 2700
Standard pallets
Turntable pallet wrapper for loads up to 1300 × 1100 mm and 2000 kg, with 0–250% motorised pre-stretch.
How a Heavy Duty Line works
Bundles are loaded onto the infeed transfer tables and moved onto the heavy-duty roller conveyor, which feeds them through the orbital ring. While the conveyor advances the bundle, the ring rotates at an adjustable 10–80 rpm and wraps 23–35 micron stretch film around it with a controlled overlap. Because the bundle keeps moving, even very long loads are covered from end to end with the same tension.
Wrapped bundles continue to the outfeed conveyor and transfer tables for unloading. Line length, roller pitch and load capacity are engineered for each project, so the line is built around your heaviest and longest bundle rather than a catalogue standard.
Where bundles must also be banded, or where a tight shrink pack is preferred, Shrink Nylon Lines enclose the bundle in PE shrink film and band it in one line.
Stretch film or shrink film?
Both protect the bundle; they suit different products and plants.
| Orbital stretch wrapping | PE shrink film line | |
|---|---|---|
| Typical product | Steel tubes, heavy profiles, long loads | Aluminium, steel, wood and PVC profile bundles |
| Bundle length | Unlimited | Up to 6000 mm |
| Film | 23–35 micron stretch film | 70 micron PE shrink film |
| Heat | None | Heat shrink after wrapping |
| Edda solution | Heavy Duty Lines, Spinner 2200 S | Shrink Nylon Lines |
Proven with heavy industrial loads
In Detroit (USA), a building materials manufacturer runs a Spinner 2200 S Pallet line with heavy-duty roller conveyors designed for loads of up to 3 tonnes. Loads are dropped at the infeed by forklift, wrapped automatically and queued in a buffer zone at the outfeed, with safety fences, light curtains and emergency stops around the cell.

What to check when choosing a tube and pipe packaging line
- Bundle size: the largest cross-section, the longest bundle and the heaviest load the conveyors must carry.
- Protection: stretch film for full coverage of very long loads, or shrink film and banding for compact profile bundles.
- Corrosion risk: storage time, outdoor yards and sea freight call for more film overlap.
- Handling: crane, forklift or transfer tables at the infeed and outfeed.
- Integration: connection to cutting, bundling or strapping equipment already in the line.
- Space: floor length for conveyors and safe access around the wrapping cell.
Frequently asked questions
What can Heavy Duty Lines wrap?
Steel tubes, pipes, metal and wood profiles and other long, heavy loads of unlimited length; the minimum product size is 100 × 20 × 1400 mm (W × H × L).
Can conveyors be sized for very heavy bundles?
Yes. Conveyor length, roller design and load capacity are engineered per project. Send us your bundle weights and dimensions.
Which stretch film is used?
Heavy Duty Lines use 23–35 micron stretch film, 170 mm wide, on Ø230 mm rolls with a Ø76 mm core. The Spinner 2200 S machines use 500 mm wide film.
When is a pallet wrapper the better choice?
When tubes or parts are shipped on pallets or in crates rather than as long bundles. Turntable wrappers suit standard pallets; the Robowrap robot wraps oversized or very heavy loads where they stand.
Can the wrapping line run automatically?
Yes. Infeed, wrapping and outfeed can run without an operator at the wrapper, with sensors, transfer tables and buffer zones designed around your flow.
