Automatic L Bar Sealer + Tunnel
The Automatic L Bar Sealer + Tunnel is a fully automated shrink wrapping solution used to seal, cut, and shrink packaging film in one continuous process. It is typically installed in manufacturing plants, logistics centers, and export packing facilities handling repeatable packaging volumes. This Automatic L Bar Sealer Tunnel supports pack dimensions up to 450 mm in width and operates at speeds reaching 25 units per minute, making it suitable for Saudi Arabia’s high-throughput industrial environments.
In industrial areas around Riyadh and Dammam, the Automatic L Bar Sealer + Tunnel is frequently used in food processing units, pharmaceutical packaging lines, and hardware manufacturing facilities. It supports sealing and cutting dimensions up to 500 × 400 mm and accommodates products with heights up to 300 mm, covering most carton-based applications.
The tunnel section operates with adjustable airflow and conveyor speed, allowing controlled film contraction without distortion. Automatic film feeding supports stable operation during long production runs. The machine layout is suitable for integration into conveyor-based end-of-line systems common in Saudi factories, where consistent output and minimal downtime are operational priorities.

Frequently Asked Questions
Saudi factories in areas like Riyadh and Dammam often handle large batch runs. This system supports automated, repeatable packaging with minimal manual input. It integrates well with upstream conveyors, making it suitable for continuous production environments where consistency and uptime are operational priorities.
The sealing frame and conveyor spacing allow a defined size range without mechanical reconfiguration. Operators typically adjust sealing time and tunnel temperature rather than hardware. This flexibility is useful in Saudi facilities that package multiple SKUs within the same shift.
POF is widely used for retail and export packaging due to clarity and strength. PVC may be used for rigid items, while PP suits lighter loads. The machine supports all three, allowing plants in Jeddah and Jubail to standardize equipment across departments.
Higher conveyor speeds reduce dwell time, which can affect film contraction if temperatures are not balanced. Saudi operators often fine-tune tunnel airflow and heat zones to maintain wrap quality while running near maximum output during peak production periods.
Standard operation does not require compressed air unless a pneumatic sealing frame is specified. Many Saudi plants choose pneumatic options to improve sealing pressure consistency, particularly when packaging heavier cartons or rigid products.
