Stretch film and shrink wrap are common packaging materials, but are they the same? While both secure goods, they differ in application, properties, and purpose. Understanding these distinctions helps businesses pick the right solution for their needs. Let’s break it down.
What Is Stretch Film?
Stretch film, often made from polyethylene, is a flexible, elastic material stretched around items to hold them tight. Known for its stretching capability—up to 300%—it clings without adhesives, making it ideal for palletizing. stretch film’s puncture resistance and lightweight nature suit logistics and e-commerce. Think pallets of boxes wrapped securely for shipping.
What Is Shrink Wrap?
Shrink wrap, typically polyethylene or PVC, is a heat-activated film that shrinks tightly around products when heated. It conforms to item shapes, offering a protective, tamper-evident seal. Statista [link: https://www.statista.com/topics/1709/packaging-industry/]
notes its popularity in retail for individual items like electronics or food packs. Imagine a DVD case or a tray of bottles encased in tight plastic.

- Properties
- Stretch Film: Elastic, reusable if intact, excels in load stability.
- Shrink Wrap: Rigid post-shrink, offers dust and moisture protection.
- Cost and Equipment
- Stretch Film: Lower cost, no heat tools required.
- Shrink Wrap: Higher cost due to heat equipment, per Logistics Management [link: https://www.logisticsmgmt.com/packaging-solutions].

highlights their role in sustainable packaging trends for 2025.
Which Should You Choose?
- Stretch Film: Best for pallet loads, heavy-duty shipping, or bulk storage.
