Flow Wrapping -- a.k.a. Fin-Seal Over Wrapping or Candy Wrap – is the automatic process of wrapping a product(s) in a pouch manufactured in line from flat film, typically Poly Propylene. The machinery and process that are utilized to perform this function produce a package that sports a seal on its back side resembling a fish’s “fin”. This cost effective process is widely used in product give-aways, sample mailings, magazine inserts, and a variety of other promotions. Over wrapping offers a more cost-effective means of loosely containing pre-packaged items or printed material in a see-though, opaque or printed tamper-resistant medium. This process is also known as "fin-seal wrapping" or "flow wrapping".
Pouches which are produced on automatic equipment, primarily for the snack food industry, food bars, trading cards and other high volume industries use equipment known as Vertical Fill and Seal (VFFS) and Horizontal Fill and Seal (HFFS) equipment. These machines produce a package which has a seal down the back side of the package referred to as a "fin" seal.
Additionally, multiple items can be collated and the finished item can be incorporated into another package.
