A semi-automatic shrink wrap machine is an excellent mid-level machine for companies doing several thousands of Semi-Automatic Shrink Wrap Machine products per day. We often recommend newer, growing companies to start with manual impulse sealers or I bar sealers. These smaller less productive machines only cost a few thousand and can accommodate a few hundred products of production per day.
As the business and production grows we recommend stepping the machine up to a semi-automatic shrink wrap machine. A semi auto machines offers several benefits over I bar sealers and impulse sealers. Let’s look at the advantages of a semi auto machine over manual.
L-Bar Sealer – Semi automatic shrink wrap machines come with an L bar sealer which is designed to be more efficient than I bar sealers. The L bar sealer seals and cuts all open sides in one motion. An impulse sealer or I bar sealer requires users to rotate the product after the first seal to make the final seal.
Magnetic Hold Down -The magnetic hold down holds the sealing bar down to complete the seal. This allows a worker to begin preparing the next product to be sealed.
Discharge Conveyor – The discharge conveyor is a conveyor found between the L bar sealers. The conveyor transports products from the sealer to the shrink tunnel after the magnetic hold releases.
Shrink Tunnel – A shrink tunnel is by far the most time efficient advantage to a semi auto machine over a manual machine. A shrink tunnel uses a conveyor to transport products through a heated area. Once the film is heated and shrunk, finished products exit the shrink tunnel.
