Complete shrink wrap line
An L sealer with shrink tunnel gives a complete shrink wrapping route: film folding, L-shaped sealing and controlled heat shrinking. The correct pairing depends on pack size, film type, output and the finish required after the tunnel.

A strong L seal will not produce a clean pack if the tunnel is too small, too short or too slow for the product. The tunnel aperture, belt speed and airflow need to match the seal output and film type.
This route suits boxes, books, printed packs, retail cartons, small kits, stationery, cosmetics and electronics packaging where a neat presentation wrap is needed.
Measure infeed space, operator access, outfeed clearance, conveyor height, power, air and future product sizes before choosing the equipment.
| Product | Send length, width, height, weight, photos and the largest and smallest pack sizes. |
|---|---|
| Film and finish | Confirm whether the priority is retail presentation, transit strength, tamper evidence or product protection. |
| Output | Confirm target packs per minute, daily volume, loading method and whether the product arrives from another machine. |
| Site | Confirm floor space, power, compressed air, conveyor height, access and any upstream or downstream equipment. |
FAQ
The tunnel applies controlled heat after the film is sealed so the film tightens around the product.
Tunnel temperature, belt speed and airflow can usually be adjusted, but POF and PE film behave differently and must be checked.
Product size, pack weight, film type, required output and available site space are the most useful details.
