Flow Wrapper Machine

Flow wrapper is commonly used in the packaging industry to wrap a wide range of products in a continuous film of packaging material, creating a sealed package.

The three actions carried out by this machine include infeeding and spacing the items, wrapping the items in film, and finally sealing and releasing the finished product. The packaging must be reliable, professional, and protective without losing speed. Form fill seal machine is another name for flow wrappers.

Food, personal care, home goods, and other industries along with other sectors quite often use horizontal flow wrappers.

What is the working principle?

Here is how the flow wrapper works:

  1. Unwinding and Feeding the Packaging Material: The packaging material, typically a roll of flat flexible film or a web, is unwound from a roll and fed into the machine. The film travels over rollers and through various guides to ensure proper alignment.

  2. Product Feeding: The product to be packaged is placed onto an infeed conveyor, which carries it towards the packaging area. The products are usually spaced evenly to ensure proper packaging.

  3. Forming the Packaging: As the packaging material travels through the machine, it passes over a forming tube or collar that shapes it into a tube-like structure around the product. The film is folded around the product, creating a partially sealed tube.

  4. Sealing the Back Seal: The partially formed tube passes through a sealing station, where a horizontal heat seal bar or rotary sealing wheels create a longitudinal (back) seal along the length of the package. This seals the film together to form the back of the package, with the product enclosed inside.

  5. Product Insertion: The product, now enclosed in the partially sealed tube, is pushed or guided into the sealing area as the film continues to move.

  6. Sealing the End Seals: As the product moves into the sealing area, horizontal sealing bars or wheels create two transverse (end) seals—one at the leading end and one at the trailing end of the package. These seals close the package, creating a fully enclosed and sealed pouch around the product.

  7. Cutting and Separation: After the end seals are made, a cutting mechanism, often a rotary knife or reciprocating blade, cuts the individual packages apart from the continuous film.
