Overwrapping and Flow Wrapping Services Overwrapping offers a more cost-effective means of loosely containing pre-packaged items or printed material in a see-through, opaque or printed tamper-resistant medium. Flow WrappingAlso known as “fin seal wrapping”, “fin sealing”, “cello wrapping” or even “flow wrapping,” we’ve used this popular packaging service on a wide range of projects, including multi-million piece premium giveaways for national fast food chains. Overwrapping is a HFFS packaging process where items are wrapped with film and sealed on the two short ends and down the rear of the package. Additionally, multiple items can be simultaneously overwrapped and the finished item can even be incorporated into another package. We can use print-registered or random print on clear or opaque film structures to create an appealing, tamper-safe package for everything from magazines and stickers to phone cards, collector cards, miscellaneous premiums and much, much more.
