Clamco 4S-XL Side Sealer Shrink System

Product Summary:

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:

1. 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.
2. The two side sealers are automatically positioned based on the measured product width. The side sealers also automatically adjust in height for vertical centering on the package. As the product transfers through the two side sealers, a four-sided seal is created. The side sealers will also trim the excess film and discharge the trim into a receptacle outside of the machine.
3. A shrink tunnel designed to handle random sizes of large products after the sealing cycle is complete, the package is automatically transferred into the shrink tunnel. The shrink tunnel will be preset for the inside tunnel temperature range and the appropriate conveyor speed. As the product moves inside the shrink tunnel, the film will be heated to reach the temperature for effective shrink. This process is optimized with variable air velocity and operational airflow controls to properly direct heat. A blower fan will direct cooler ambient air toward the shrink wrapped product to further assist in shrinking the film when using polyethylene.
4. In the final step, the product is then discharged onto an exit conveyor, which can be aligned with either a customer provided conveyor and/or other material handling device for further packaging.
