PackForge S Series Shrink Tunnels

What is a shrink tunnel, and which S series size fits?

Inside, heaters warm the air while a conveyor carries each sealed pack through at an adjustable speed, so the film shrinks evenly as it passes. The S260 draws 3.3 kW, moves at 0 - 6 metre per minute and heats in 5 min. The 3020, 4525, 4535 L and 6535 L draw 4.5, 6.5, 9.6 and 12.5 kW, run at 0 - 10 metre per minute and need 10 min. Every model takes 15 min to cool.

Choose by load as well as size. The S260 carries 5 kg and suits small cartons on a bench. The 3020 and 4525 take 10 kg, enough for cosmetics, pharma or stationery boxes. For beverage bundles and heavy multipacks, the two biggest models handle 30 kg. Weights run from 40 kg to 150 kg. Buyers wanting sealer and tunnel matched from day one can look at the 5545A.
