4S-XL Side Sealer Shrink System

4S-XL Four Side Sealer and 10T Shrink Tunnel System

Shrink wrap protection for extra-large packages, with automatic width, length, and height adjustment on every pack!

The Clamco model 4S-XL Four Side Sealer and 10T Shrink Tunnel is an advanced shrink packaging system that makes a four-sided seal around each product. Unlike traditional bundlers or sleeve wrappers, this shrink system ensures that the product being packaged is fully enclosed. Equipped with Automatic Detection of Product Width for Side Sealer Positioning, this cutting edge four side sealer can create packages of different sizes in one packaging run.

The packaging process is as follows:

First, the product is placed onto the infeed conveyor belt. A positioning guide automatically centers the product on the conveyor. Next, the cross seal bar will be activated by sensors that detect the product length. The film is fed on demand via two side-mounted powered film cradles. The product is now wrapped with film on the top and bottom.
