Fin seal packaging (also called flow wrapping) is a high-speed, large volume process of loosely containing a product in sealed tamper-resistant film. Seals are created at two ends of the package, with another seal, the fin seal, along the middle of the back of the package.
This popular packaging method is often used for small food products such as snack bars, printed material such as magazines and mailers, collector trading cards, and promotional premiums.
Pro Pac supplies flow wrapping film in all available materials. Fin seal material can be clear or opaque, printed or plain, single layer film or multilayer laminate structures.
Simple single layer polypropylene film is perfect for protecting your products for bulk packing.
Custom printed multi-layer laminates, possibly with metalized polypropylene and other barrier materials, are specifically designed for each individual food product. Barrier film made for MAP gas flushing will extend the shelf life of deli and other food products.
Other films are formulated to comply with mailing standards, perfect for large mailing projects and premiums.
