Frequently Asked Questions

The CN-4520A is a compact automatic tunnel suited to tabletop or free-standing use with a moderate 11-pound load capacity, making it a reasonable fit for smaller operations. The ST-series steps up considerably with full re-circulating airflow, four-directional heating, and a variable-speed AC conveyor running 0-35 feet per minute, built for higher-volume, more demanding packaging environments. Match the model to your actual daily package volume rather than choosing based on price alone.

Several ST-series models reach 300°F in under 15 minutes, which matters if your operation needs to start production quickly rather than waiting through a long warm-up cycle before the first item can run through. Pairing the tunnel with a compatible unit from the impulse sealers by SealerSales range for pre-sealing bags before they enter the tunnel can further streamline a fast-paced packaging line.

Some clearance is fine and often necessary for even shrink coverage, but going too large wastes both energy and shrink film effectiveness on packages far smaller than the chamber. Chamber sizes across these models range from an 18"W x 6"H x 20"L compact option up to an 18"W x 16"H x 44"L unit for larger products. Choose a chamber sized reasonably close to your typical product dimensions rather than defaulting to the largest available option.

These tunnels are built to handle both PVC and polypropylene films across the range, giving you flexibility to switch film types based on project needs like clarity, cost, or environmental considerations without needing separate equipment for each film type. If you're assembling a full packaging setup, the shrink wrapping kits by SealerSales options bundle compatible film with sealing equipment for a more complete starting setup.

Look for thermal overload protection and an anti-jam safety feature, both of which are included on several models here and matter significantly for equipment running unattended for extended stretches. Automatic cool-down and shut-off functionality also extends heater lifespan by avoiding unnecessary heat exposure between runs. For a production line running heavy daily volume, browsing the SealerSales equipment range alongside the tunnel itself can help you confirm which upstream sealing equipment pairs well with your chosen model.
