Edda builds PE shrink wrapping machines with integrated heat tunnels that bundle bottles, cans, jars, cartons and trays into tight, stable multipacks. The film is sealed around the group and shrunk in the tunnel, so the units travel as one pack from the filling line to the shop shelf – without cardboard trays where they are not needed.
Why multipacks need PE shrink film
Bottles and cans are heavy, slippery and easy to knock over. A multipack has to hold its shape through palletising, truck transport, warehouse handling and the customer carrying it home. Thick polyethylene shrink film does this well: it is strong, tear-resistant and shrinks tightly around the group, so six or twelve bottles behave like one product.
- Loose units fall over and break between filling and palletising.
- Cardboard trays and wrap-around cases add material and cost to every pack.
- Hand bundling cannot keep up with filling and labelling lines.
- Weak or loose film lets packs fall apart when they are lifted.

How PE shrink wrapping works
Products are grouped and conveyed into the sealing station. PE film from the upper and lower rolls forms a curtain around the group; the sealing bar closes, seals and cuts the film. The wrapped bundle then travels through the heat tunnel, where the thick PE film shrinks tightly around the units and holds them together as one stable, easy-to-handle pack.
All models take PE shrink film from 20 to 100 micron. Thinner film is enough for light, low packs; heavier film is used for large bottles and packs that will be carried by hand. The open ends of the film form the familiar “bull’s eyes” at the sides of the pack, which keep the units in place and make the pack easy to grip.

|---|---|---|---|---|
| Nouva 4065 | 200 mm | 600 mm | 650 mm | 12 packs/min |
| Flexia 4075 | 300 mm | 700 mm | 750 mm | 10 packs/min |
| Flexia 4085 | 300 mm | 800 mm | 850 mm | 10 packs/min |
| Flexia 4095 | 300 mm | 800 mm | 950 mm | 8 packs/min |
| Uniqa 4075 | 300 mm | 700 mm | 750 mm | 20 packs/min |
| Uniqa 4085 | 300 mm | 800 mm | 850 mm | 15 packs/min |
| Uniqa 4095 | 300 mm | 900 mm | 950 mm | 12 packs/min |
Capacity depends on pack dimensions. All models run on 380 V, 50/60 Hz three-phase power; installed power including the heat tunnel ranges from 16.5 kW (Flexia 4075) to 34.5 kW (Uniqa 4095). Full specifications are in the product catalogue.
Flexia, Uniqa or Nouva?
- Uniqa is the automatic, highest-output series, for packs coming straight from a filling or labelling line.
- Flexia puts the sealing station and tunnel on a shorter frame with a smaller main motor – a space- and energy-efficient choice for medium volumes.
- Nouva 4065 is designed for lower packs up to 200 mm high, such as cans, jars and flat cartons.
What else PE shrink film can bundle
- Food and beverage multipacks: water, juice and soft drink bottles, cans, jars
- Bakery, dairy and other food multipacks
- Bundles of cartons, boxes and trays for logistics
- Ceramic tiles, building materials and industrial parts
- Personal care, household and healthcare product packs

PE or POF shrink film?
PE film is thicker and stronger, so it is the right choice for heavier multipacks and bundles that must stay together in transport. POF film is thinner, clearer and glossier, and is preferred for single retail products, printed matter and gift sets. See our POF shrink wrapping machines for printed matter and retail products.
What to check when choosing a PE shrink wrapper
- Pack format: number of units, pack height, width and length.
- Output: packs per minute from your filling or labelling line.
- Film: thickness for the pack weight, and whether you print on the film.
- Infeed: manual grouping or automatic feeding from an existing conveyor.
- Energy and space: tunnel power and the floor area available.
- End of line: how finished packs are palletised and wrapped.
Frequently asked questions
Which products can a PE shrink wrapper bundle?
Bottles, cans, jars, cartons, trays and similar products grouped into multipacks, as well as tiles, building materials and industrial parts.
Which film is used?
PE shrink film from 20 to 100 micron, up to 600–900 mm wide depending on the model.
What output can I expect?
Up to 20 packs per minute (max.) on the Uniqa 4075, 15 on the Uniqa 4085 and 12 on the Uniqa 4095 and Nouva 4065. Actual output depends on pack dimensions.
How tall can the pack be?
Up to 300 mm on the Flexia and Uniqa series and up to 200 mm on the Nouva 4065.
Do I need cardboard trays?
Not always. Many multipacks are bundled in film only; trays or pads can be added where the pack needs extra stiffness.
