Pneumatic L Sealing Machine

HUALIAN BRAND BSL series pneumatic l sealing machine can convey the products automatically into shrink tunnel through conveying belt for shrink packaging after sealing & cutting. Equipped with shrink tunnel to reach higher working capacity.

The pneumatic l sealing machine can wrap approximately 16 items per minute (depending on operator speed). This unit is suitable for Polyolefin and/or PVC shrink packaging materials. Once the operator places the product on the seal table, he begins the packaging process by pressing a dual push button system. Pneumatic pistons push down the seal bar and drive it up once the cycle is completed. Subsequently, the motorized conveyor system engages, which transports the product into an optional shrink tunnel. The seal bar may also be actuated automatically by switching the machine to the auto mode and adjusting the sealing time interval.


  • A safety device that prevents the sealing knife from overheating and guarantees the operator's safety.
  • Nano-fiber cutter holder and anti-sticking thermostable nichrome cutter that ensure good sealing without cracking or coking.
