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 across standard-duty and heavy-duty classes from Heat Seal, Max-Air and Preferred Packaging, including standalone tunnels (Heat Seal T-series, Max-Air T4822 and T4832) and integrated L-sealer plus tunnel combos (Preferred Packaging PP-1519 EC, PP-1622MK). 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-1519 EC, PP-1622MK) pair both a sealer and a tunnel in one machine.
Standard-duty vs heavy-duty tunnel?
Heavy-duty tunnels (for example TX5218 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.
