Weldotron 7121 Shrink Tunnel
This industrial machine is a Weldotron 7121 Shrink Tunnel, which is used in high-volume production lines to shrink plastic film tightly around products.
Specs:
Electrical: 230 Volts, Single Phase, 60 Cycles, 35 Amps, 7,000 Watts (7kW)
Chamber Dimensions: 16" wide x 8" high aperture with a 46" to 47" long heating chamber
Controls: Features adjustable analog temperature controls (up to 450°F) and variable conveyor speed
Preparation: A product is wrapped in loose shrink film (often using a companion machine like an L-Bar Sealer)
Heating: As the conveyor carries the product through the tunnel, a "heater bank" and blower motors circulate hot air
Shrinking: The heat causes the molecules in the plastic film to contract, pulling the film tightly and uniformly around the product’s shape
Cooling: The product exits the tunnel with a finished, professional-looking "shrink-wrapped" seal
It is typically used for primary and secondary packaging of various items, such as:
Retail Goods: Board games, software boxes, and frozen pizza boxes
Bundling: Grouping multiple items together, like multi-packs of water bottles or cans
Protection & Tamper-Evident Seals: Applying protective sleeves or tamper-evident bands to bottles and containers
Dimensions (l x w x h): 71.5" x 20.5" x 60.5"
