How Flow Wrap Machines Work

The working principle of horizontal flow wrap machines involves a series of automated steps to efficiently package products:

  1. Film unwinding: A roll of packaging film, typically made of materials like polyethylene or polypropylene, is unwound and fed into the machine.
  2. Product loading: Products are placed onto the infeed conveyor, either manually or automatically, and transported to the forming area.
  3. Film forming: The flat film is formed into a tube around the product as it passes through a forming collar or former.
  4. Sealing: The machine creates a longitudinal seal (fin seal) along the length of the tube and then cross seals (end seals) to encase the product completely. Sealing is typically done using heat and pressure.
  5. Cutting: A cutting mechanism, often a rotary knife, separates the individually wrapped products by cutting the film between them.
  6. Product discharge: The wrapped products are discharged from the machine, ready for further processing or packaging.

Horizontal flow wrap machines can package goods at high speeds without sacrificing consistency or quality, thanks to this automated, continuous operation.

For best results, we advise modifying the machine’s settings (bag length, sealing temperature, conveyor speed) to account for various product sizes and packaging needs.
