BOPP and polyolefin shrink film both show up constantly in packaging conversations, but they're built for very different jobs. Confusing the two can mean a product that doesn't seal right or a machine that can't process the film you bought. Here's how they actually differ.
What BOPP Film Is Built For
BOPP (biaxially oriented polypropylene) is a clear, rigid film most commonly used for flow wrapping, labels, and bag overwrap where clarity, stiffness, and a crisp finish matter. It doesn't shrink — it wraps and seals around a product at a fixed size, which makes it a strong choice for snack packaging, baked goods, and other flow-wrapped items. Our BOPP film is built for consistent sealing on flow wrap lines.
What Polyolefin Shrink Film Is Built For
Polyolefin shrink film is designed to shrink tightly around a product when heat is applied, conforming to its exact shape. It's the go-to choice when you need a snug, tamper-evident seal on irregularly shaped products, multi-packs, or retail bundles. Browse our shrink film collection for standard and cross-linked options.
Key Differences at a Glance
- Shrinks with heat: Polyolefin does; BOPP does not.
- Best for: BOPP suits flow-wrapped, uniformly shaped products; shrink film suits irregular shapes and bundles.
- Finish: BOPP gives a crisp, flat wrap; shrink film gives a tight, contoured seal.
Which Machine Do You Need?
BOPP is typically run on a flow wrapper, while shrink film runs through a sealer and tunnel setup. If you're not sure which line matches your product, that's the first question to answer before choosing a film.
