Electric Heat Tunnel, Double Zone Shrink Tunnel
Double zone electric heat shrink tunnels are used to shrink sleeve films such as PVC, POF, PE, PP and OPS after they are applied to containers. They use two heating sections, one above and one below the conveyor, to heat the film from different directions during the shrinking process. The upper and lower heating sections distribute heat more evenly around the container, which is useful for products with different shapes and sizes.

Features
- Upper and lower heating sections provide more balanced heat distribution inside the tunnel.
- 2–3 independent temperature zones with ±2–5℃ control accuracy adapt to different shrink film requirements.
- Independent upper and lower airflow systems improve heat circulation and reduce sleeve wrinkles and air bubbles.
- Insulated panels and stainless steel exterior reduce heat loss and improve operating safety.
- Adjustable airflow direction supports precise shrinking for areas such as bottle necks and shoulders.
- Adjustable tunnel height (available on selected models) allows easy integration with different production lines.
