Shrink Tunnel Machine
A Shrink Tunnel Machine is a thermal packaging system used to apply heat to shrink film around a product. Commonly integrated with L-bar sealers or sleeve wrappers, it ensures tight-fitting, tamper-evident, and protective packaging by shrinking the film using heat as the product passes through a temperature-controlled tunnel.
Features
Variable Conveyor Speed: Adjustable for different product throughput.
Precise Temperature Control: Digital thermostat ensures even heat distribution.
Adjustable Airflow: Controlled fans provide uniform shrink without scorching.
Energy Efficient Insulation: Reduces heat loss and increases safety.
Safety Mechanisms: Emergency stop, heat shield, overload protection.
Mobility Options: Heavy-duty casters with lock brakes (optional).
Operator Panel: User-friendly touchscreen or button interface.
Applications
Food & Beverage Packaging: Multipacks, frozen food, bottled drinks.
Pharmaceuticals & Cosmetics: Tamper-evident packaging for boxes and bottles.
Retail & Electronics: Consumer products with visual merchandising appeal.
Industrial Goods: Bundling parts or boxed hardware for distribution.
