CLASSIFICATION
Main Types of Shrink Heat Tunnels
So, what kind of shrink tunnels are out there? You’ve heard of hot air, steam, and even infrared heating ovens.
As for us, we mainly build two kinds, depending on how they generate heat.
Hot Air Shrink Tunnels
Primarily use heated air as the heat transfer medium, circulating hot air to shrink film
Steam Shrink Tunnels
Transfer heat by injecting steam into the tunnel, shrinking film. Ideal for heat-sensitive products
Electric or Steam? Shrink Tunnel Comparison at a Glance
| Feature | Electric Heat Shrink Tunnel/Hot Air Tunnel | Steam Shrink Tunnel |
|---|---|---|
| Output Speed | Max 100 pcs/min | 100–150 pcs/min |
| Temperature | 110–180°C | 90–100°C |
| Applicable Film | POF, PE, PVC, OPS | PETG, PVC, OPS etc. |
| Shrink Effect | Good | Excellent |
| Energy Consumption | Lower (~15 kg/h) | High (27–30 kW/h) |
| Maintenance | Low maintenance compared to steam tunnels | Requires at least daily water drainage |
| Application Scope |
Suitable for moisture-sensitive products such as dry food, biscuits, and tea. Ideal for small-batch packaging lines. Used in industrial goods like tapes and electrical materials. |
Designed for high-output lines and bulk production with strict packaging quality. Best for liquid product labeling (e.g., beverages, wine). Excellent for PETG and special label shrinking. Handles irregular-shaped containers. Suitable for moisture-resistant products. |
| Equipment Cost | USD 1100–3600 depending on configuration | Approx. USD 4500 for standard TY-W300 model |

TENGYI Shrink Heat Tunnels: Versatile, Customizable, Safe
Temperature Versatility
For POF film, 130-150°C is usually sufficient. Our hot air shrink tunnel is also compatible with all other film types, capable of reaching up to 180°C (356°F) for broader applications.
Customizable
Conveyor Speed: Standard 20m/minute; customizable to your production pace.
Tunnel Size: Customizable dimensions to fit all product sizes.
Conveyor Material Options: Choose between Teflon Mesh Belt (for lighter/irregular items) or Stainless Steel Roller Conveyor (for heavier/larger items).
Auto-Shutdown Safety
TENGYI hot air shrink tunnels auto-shut down if temperatures exceed set by 5°C, preventing fire hazards for secure operation.

Core Controllers for Hot Air Shrink Tunnels
-
Temperature Controller:
Precisely regulates chamber temperature, maintaining it within ±1–2°C of the set point (e.g., 130°C), ensuring consistent operation and optimal shrink performance. e.g The TY-5030 is equipped with Omron Temperature Sensor
-
Conveyor Speed:
The TENGYI hot air shrink heat tunnel's conveyor typically runs at 20 meters per minute, which works great for most items. But don't worry, if your products need a different pace, we can customize for you!
