What is flow wrapping? Flow wrapping is a horizontal-motion process in which product of any shape is wrapped in clear or printed polypropylene film. The end result is a flexible package with a non-lap type seal on the bottom and crimped end seals. Synonyms include fin-seal wrapping, crimp-seal wrapping, horizontal bagging and pillow-pouch wrapping.
Good flow-wrappers get the film tightly around the product to minimize product shift within the package and minimize  the "tails" on the product as they make case-packing more difficult.
 
Both the process and films in flow wrapping are quire different from overwrapping, Flow wrap BOPP films, for example, need only to seal to themselves. Overwrap films need to seal to themselves and the other side of the film. There are zillons of products that are flow-wrapped,like biscuit, candy bar, soap, chocolate,etc. Products for flow wrapping do not need to have a flat bottom, flat sides or a minimum height to be wrapped. So the flow wrap machine is with wide application.
