A shrink tunnel applies even, controlled heat to shrink film tight around a product after it has been wrapped - the finishing step after an L-bar or I-bar sealer. Mid-State Litho carries heat shrink tunnels in standard-duty and heavy-duty classes from Heat Seal, including the Max-Air line, and integrated sealer plus tunnel combos from Preferred Packaging. Whether you are shrink-banding printed pieces or bundling full cartons, our team helps match tunnel size, belt width and wattage to your product and throughput. Pair a tunnel with the right shrink wrap sealer, or browse the full shrink wrapping equipment hub.
Frequently Asked Questions
What does a shrink tunnel do?
It applies controlled heat to shrink film tight around a wrapped product, giving a clean, finished pack.
Do I need a sealer too?
Yes. A tunnel finishes what an L-bar or I-bar sealer wraps. Combo units (PP-1622MK) pair both a sealer and a tunnel in one machine.
Standard-duty vs heavy-duty tunnel?
Heavy-duty tunnels (for example the T4832 and the HDX250 combo) run higher wattage and larger openings for cartons; standard-duty tunnels (T2615, T2622) suit printed pieces and small bundles.
Does Mid-State Litho help pick one?
Yes. We size tunnel opening, belt width and wattage to your product and volume - just reach out with your application.
What size tunnel do I need?
Measure the largest wrapped product you run, then add clearance on width and height. The T2615 opening is the entry size and the T4832 is the largest standalone tunnel MSL stocks, at $8,830 and $24,790. Belt width and wattage climb with the opening, so a tunnel sized only to today's product leaves nothing for a larger job later.
Bundling instead of shrinking? See our banding machines and packaging supplies. Heat Seal is the dominant tunnel brand in this lineup - browse all Heat Seal packaging equipment.
