Sintesi

An online labeling, sealing and shrinking machine labels each product, seals it in shrink film and shrinks the film tight, all in the production line with no one handling the product. It suits rolls, boxes and packs that need a label and a clean, dust-proof wrap. Our equivalent solution combines a labeler with a motion sealer and shrink tunnel. This page explains the order of the stations, how to check that a product fits, and how to work out film use.

White paper or nonwoven rolls with a center hole move along a roller conveyor. Pneumatic grippers and guide plates square each roll, then clear film is fed around it and sealed. The roll passes under a red heating hood where the film shrinks tight, and orange mesh fencing closes off the seal and shrink area. A barcode label sits on each product.

Why label and shrink in line

Done offline, labeling and wrapping need people to pick, stack and re-feed every product. In line, each product is labeled and wrapped as it leaves production. Labels match the product, nothing piles up, and the wrap keeps dust off rolls of tissue, nonwoven or film from the first minute.

Le stazioni in ordine

Infeed and positioning: guides and grippers align and center the product on the conveyor.
etichettatura: a labeler applies the barcode or product label at a set position.
Guarnizione: a motion sealer wraps center-folded film around the product and seals and cuts it while it moves.
Restringimento: a hot-air tunnel shrinks the film tight.
Cooling and outfeed: the pack cools on the conveyor before stacking or boxing.

Film length is set by an electric eye and timer, so each pack gets the same amount of film.

Label under or over the film

Posizione dell'etichetta	Buono per	Stai attento
Sotto il film	protects the label from scuffs and moisture	scanner must read through film; avoid glare
Over the film	easy scanning, no film glare	label must stick to shrink film; apply after cooling

For rolls that go to retail, under the film keeps the label clean. For logistics labels scanned many times, over the film is easier.

Reference figures

For our equivalent motion sealer and tunnel:

Articolo	MO-350	MO-600
Larghezza di tenuta	Fino a 350 mm	Fino a 600 mm
Altezza di tenuta	Fino a 200 mm	Fino a 250 mm
Max film	580 mm di larghezza, 280 mm di diametro esterno	860 mm di larghezza, 280 mm di diametro esterno
Potenza	10.5kW	12.5kW
Aria	fino a 0.5 MPa	fino a 0.5 MPa
Peso	600 kg	900 kg

Both run on 380 V 50–60 Hz 3 phase at a working height of 780–820 mm. Film is center-folded POF or PE, and the tunnel conveyor uses chains with rotating silicone-coated rods. On the MO-350, product width plus height must be 400 mm or less. Labeler type and line speed are confirmed at quote.

Will my product fit?

Check three things: width against sealing width, height against sealing height, and width plus height against the product limit. A roll of 250 mm diameter and 150 mm high, lying flat (example only):

Vedi	Valore	MO-350 limit	Risultato
Larghezza	250 mm	350 mm	si adatta
Altezza	150 mm	200 mm	si adatta
Larghezza + altezza	250 + 150 = 400 mm	400 mm	al limite

A product right at the limit fits but leaves no margin. A larger roll goes to the MO-600.

Film use per pack

Center-folded film width ≈ product width + height + allowance. Film length per pack ≈ product length + height + allowance. With a 50 mm allowance for the example roll: film width 250 + 150 + 50 = 450 mm, inside the 580 mm limit, and film length 250 + 150 + 50 = 450 mm per pack. Multiply by packs per year and film weight per meter for your film budget.

Sicurezza

The machine is designed to EN ISO 12100:2010 for risk assessment, EN 415-10 for packaging machine safety and EN 60204-1 for electrical equipment. The hot tunnel and the seal knife are the main hazards; high-temperature warnings and mesh fencing close off the area.

FAQ di ingegneria

Q: Can it label and wrap rolls with a center hole? A: Yes; the film seals around the roll and shrinks over the ends.

Q: Which film does it use? A: Center-folded POF or PE film.

Q: How do I know my product fits? A: Check width, height and width plus height against the model limits.

Q: Can the label go on after shrinking? A: Yes, the labeler can sit after the tunnel once the film has cooled.
