Product Overview

Hot Water Shrink Tunnel & Tank

TRAVAC Hot Water Shrink Systems deliver a smooth, wrinkle-free finish on vacuum-sealed bags using precisely controlled hot water. The Tunnel-Type Hot Water Shrink System (left) uses high-efficiency hot water sprays for rapid, uniform shrinkage across a range of pack sizes. The conveyorised Belt-Type Vacuum Packaging & Shrink Line with integrated Dip-Tank (right) is purpose-built for largeformat products such as 20 kg Cheddar cheese blocks

System Types

Choose between our proven tunnel-type and belt-type configurations

Tunnel-Type Hot Water Shrink System

A standalone shrink tunnel using high-efficiency hot water sprays from above and below the conveyor belt. Rapid, uniform shrinkage across a range of pack sizes. The PLC-controlled panel with HMI touchscreen and stack light indicator allows precise temperature and speed management.

Belt-Type Vacuum & Shrink Line — Dip Tank

A conveyorised system combining an inline belt vacuum packaging machine with an integrated dip-tank hot water shrink stage. Purpose-built for large-format products such as 20 kg Cheddar cheese blocks. Packs are vacuum-sealed, indexed forward on the belt, and fully immersed in a temperature-controlled water bath for tight, wrinkle-free shrinkage.

Frequently Asked Questions

Find answers to common questions about our Hot Water Shrink Systems

What is this system used for, and why is it used after vacuum sealing?
It shrinks vacuum-sealed bags in precisely controlled hot water to pull the film tight against the product, giving a smooth, wrinkle-free finish that a vacuum seal alone doesn't achieve.
What's the difference between the Tunnel-Type and Belt-Type Dip-Tank systems?
The Tunnel-Type uses hot water sprays above and below a conveyor for general-purpose shrinkage; the Belt-Type Dip-Tank fully immerses packs and is purpose-built for large-format products such as 20 kg Cheddar cheese blocks.
How is shrink temperature controlled and kept consistent?
A PID temperature controller holds the water at 75°C–90°C with electric or steam heating, and a circulation pump keeps temperature even across the tank or tunnel.
What is it constructed from?
An SS 316 tank with SS 304 frame and conveyor structure, built for washdown food production environments.
Can it be integrated inline with other Travac machines?
Yes, it can be integrated inline with a thermoformer or chamber vacuum machine, and conveyor length and aperture can be customized to the line.
What products is it suitable for?
Poultry, meat cuts, seafood (including smoked fish), cheese and paneer, and sausages.
