Shrink Sleeve Tunnels

Radiant Shrink Tunnel

l-sealer 01

This tunnel is mounted onto a stainless steel frame with solid stainless steel sides and roof. The interior surfaces have a polished finish to maximise heat/radiation reflections onto the product.

Heat is generated by twelve glass radiant filaments six each side with each opposite pair having their own temperature setting control so varying levels of heat can be directed at different parts of a container for an improved shrink finish.

Overall internal tunnel temperature is kept within close tolerances by an external temperature setting controller linked to a heat sensor inside the tunnel.

With its modular design the radiant tunnel can supplied as an individual unit or for more complex shapes or higher speeds a number of units can be positioned inline. The radiant tunnel can be used at the in-feed for pre-heating containers or after the material application to achieve an adequate time/temperature gradient for the desired shrinking result.

Options available include a system to count products in and out if there is a possibility of them falling over and a motorised tunnel lift facility.

Hot Air Single Shrink Tunnel

The single length tamper band hot air model is mounted on a stainless steel frame with open mesh guards.

Hand wheels sited outside the guards for safety and ease of access allow the hot air delivery manifolds to be adjusted to ensure they are in the optimum shrinking position for varying heights and diameters of products. Heat is provided by hot air guns that have variable settings and the system has safety overload cut-outs built in.

With its modular design the hot air tunnel can be sited as an individual unit or for higher speeds a number of units can be positioned in line after the material application to achieve an adequate time/temperature gradient for the desired shrinking result.

These tunnels are available as either part of a complete system with integral conveyor or as individual units to operate over a customer’s suitable existing conveyor.

To be able to fully evaluate product shrinking requirements samples of containers and shrinkable

To fully evaluate product shrinking requirements samples of containers and shrinkable material to be used is essential. We offer a pre order testing facility on your products to ensure the correct shrink performance and you can then see the results achievable on these tunnels.
