chocolate flow wrappingFlow wrapping, also known as fin-seal wrapping, horizontal bagging, or pillow pouch wrapping, is a quick and economic packaging method used for a broad range of products.

During this process, items proceed through a flow wrapping machine, which precisely places a polymer-based packaging material over the product and seals the package. Flow wrapping incorporates three unique seals consisting of two crimps at the ends and a longitudinal fin seal that runs along the back of the package.

Manufacturers may turn to flow wrapping due to:

  • Rising operational costs
  • Increased consumer demands
  • Constant pressure to improve product packaging efficiency

The speed and seamless action of flow wrapping machines allow businesses to achieve shorter turnaround times for larger orders. Recent developments in the automation of flow packaging machines also significantly reduce labor costs, allowing you to invest more in other areas of your business.

How Flow Wrapping Works

Although flow wrapping machines come in a wide variety of forms, they all consist of the same essential elements: an infeed conveyor belt, a film feed assembly, a forming area, and a discharge area

  1. Operators first place the product on an infeed conveyor belt, which transports the product to the forming area.
  2. At the forming area, the machine wraps a layer of sealing material around the product, mating the two outside edges of the material at the bottom.
  3. The mating edges then pass through a pair of rotating fin seal wheels, which form the longitudinal seal using heat, pressure, or a combination of both.
  4. The product then moves through a series of rotating cutting heads, or end seal crimpers, that seal the front and back ends of the product while separating the adjoining products into individual packages.
  5. After this process, the machine delivers the products to the discharge area, where they accumulate for storage or further packaging.

On top of this basic model, factory managers can tailor flow wrapping machines’ packaging speed, packaging dimensions, equipment dimensions, and other optional features to their facility’s requirements.

Horizontal Flow Wrapping versus Vertical Flow Wrapping

Flow packaging operates mainly via horizontal or vertical processes. As their names suggest, vertical flow packing packages products vertically, and horizontal flow packing wraps products horizontally. Choosing between the two depends on the type of material being packaged and the desired bag type.

Horizontal flow packaging solves most packaging needs, but vertical flow packaging greatly speeds the process for loose products that can be easily dropped into the package, such as powders, granulated products, liquids, and fresh or frozen produce.
