Edda builds POF shrink wrapping machines – from compact L-bar sealers to fully continuous side sealers – for books, magazines, printed matter, stationery, cosmetics, food packs and boxed retail products. Clear polyolefin film is sealed around each product and shrunk tight in a heat tunnel, giving a clean, glossy, tamper-evident pack that shows the product and protects it.
Why retail products are shrink wrapped
On a shop shelf the pack is part of the product. Books and printed matter must stay clean and unread until they are sold, cosmetics and gift sets must look new, and multi-item sets must stay together. Thin, clear POF shrink film does all of this without hiding the product or its printing, and it shows straight away if a pack has been opened.
- Hand wrapping and heat guns give uneven, wrinkled packs.
- Dust, fingerprints and moisture spoil printed covers and boxes before sale.
- Sets and bundles come apart in transport and on the shelf.
- Packing must keep up with printing, binding or filling lines.
Which POF shrink wrapper for which output?
All models wrap products up to 150 mm high. Choose by output, product length and how automatic the process should be.
Alfa 500
Continuous, highest output
Side sealer with kissing belts and a flying cross-seal jaw: products never stop. Up to 100 packs/min (max.), unlimited length.
Admiral 500
Automatic side sealer
Side seal along the full length of the product, for items of unlimited length. Up to 60 packs/min (max.).
Supra 400
Automatic L-bar
L-shaped sealing bar (450 × 500 mm) and integrated tunnel, up to 30 packs/min (max.).
Compa 500
Compact L-bar with tunnel
Sealing station and shrink tunnel in 2730 × 900 mm, POF or PVC film, up to 15 packs/min (max.).
Electrona 300
Entry-level L-bar sealer
500 × 300 mm sealing frame on a 580 × 1340 mm footprint, single-phase power, up to 8 packs/min (max.).
Admiral 950
Long and wide products
950 mm sealing jaw and film up to 1100 mm wide for larger and long retail products.
L-bar, side sealer or continuous?
On an L-bar machine (Electrona, Compa, Supra) the product enters centre-folded film and an L-shaped bar seals and cuts two sides in one stroke. The sealing frame limits the product length, and the process stops briefly for each seal – simple, reliable and economical for small and medium volumes.
On a side sealer (Admiral) a side-sealing unit closes the long edge of the film along the product and a cross-seal jaw makes the front and rear seals. Because the side seal is not limited by a frame, product length is unlimited.
On the continuous side sealer (Alfa) kissing belts hold film and product together and a flying cross-seal jaw moves with the product, so the line never pauses. This is what allows up to 100 packs per minute.
In every case the sealed pack then passes through the shrink tunnel, where hot air shrinks the film evenly around the product.

POF or PE shrink film?
POF film is thin, clear and glossy, so it is preferred for single retail products where the look of the pack matters. PE film is thicker and stronger and is used to bundle heavy multipacks of bottles and cans. See our PE shrink wrapping machines for bottles, cans and multipacks.
What to check when choosing a POF shrink wrapper
- Product size: height (up to 150 mm on all models), width and length.
- Output: packs per minute now and in a few years.
- Product length: fixed sizes suit an L-bar machine; long or varying lengths suit a side sealer.
- Film: POF only, or POF and PVC.
- Infeed: manual loading or connection to a printing, binding or filling line.
- Space and power: single-phase Electrona or three-phase automatic machines with tunnel.
Frequently asked questions
Which machine is right for a small print shop or workshop?
The Electrona L-bar sealers run on single-phase power on a small footprint, and the Compa adds a shrink tunnel in a compact frame. Both suit small runs and mixed product ranges.
How fast can POF shrink wrapping run?
Up to 100 packs per minute (max.) on the Alfa 500 continuous side sealer, depending on product dimensions.
Can I wrap products of unlimited length?
Yes, on the Admiral and Alfa side sealers, because the side seal runs along the product instead of a fixed frame.
Which films can be used?
POF shrink film on all models; the Electrona and Compa also run PVC shrink film.
What is the maximum product height?
150 mm on all POF series.
What information do you need for a quote?
