Automatic L-seal cutting machine is a fully automatic unmanned L sealing cutter, widely used for lot production pipelining with high efficiency. The machine is equipped with an auto film feeding & perforating device and adjustable product infeed conveying table in order to meet different requirements from different products.
Fully automatic L-sealers are high-speed L-sealing solutions for wrapping using polyolefin film. The automatic L-sealers can be used in combination with shrink tunnels.
automatic L-sealers are ideal for high speed, providing excellent performance and value for money.
The complete system consists of a fully automatic L-sealing machine and a separate heat shrink tunnel.
The speed of the system is up to 25 packs per minute. The machine is fully automatic and an operator is only required for loading packets, monitoring, and film changing.
L-Sealer Tetra Pack Machine
The L-Sealer Tetra Pack Machine is an industrial packaging solution designed to seal Tetra Pack cartons securely and uniformly. It uses an L-shaped sealing arm to wrap the carton edges with heat or pressure, creating airtight, tamper-proof, and professional-quality seals.
This machine ensures product integrity, hygienic packaging, and efficiency in high-volume production environments, commonly used in beverage, dairy, juice, and liquid food industries.
How the Machine Works: Step by Step
Carton Loading
Operators place filled Tetra Pack cartons on the infeed platform or conveyor.Positioning & Alignment
Sensors or guide rails align the carton precisely to ensure accurate sealing.L-Sealing Process
The L-shaped sealing arm moves over the carton edges.
Heat or pressure is applied to seal the film along the top and side edges simultaneously.
Cutting & Trimming
The machine cuts excess film and ensures clean, uniform edges.Discharge
The sealed carton exits via the outfeed conveyor, ready for packing, storage, or shipping.
Key Features & Operational Benefits
