Shrink Film or Stretch Wrap (What’s the Difference?)

It’s easy to confuse shrink film and stretch wrap. Here’s how they differ:

Shrink film—made by Clysar—is a flexible packaging film that is sealed around a product and heated in a shrink tunnel. The film then shrinks in all directions for a tight, clear fit. Clysar® shrink film is a polyolefin with specially engineered properties for strength, clarity, shrink performance and line speeds. It can be very thin for wrapping lightweight products or thicker for applications like bundling multiple packages or replacing corrugate shippers.

Stretch wrap—which is NOT made by Clysar—is a thick, strong, stretchy material that is wrapped around palletized shipping loads or heavy bulk products (such as bottles or cans). Stretch wrap is applied at the end of the packaging process before products leave the door, and keeps them from shifting during transport or retail distribution. Stretch wrap does not shrink, and heat tunnels or guns are not used in the packaging process.

Why Shrink Film?

Shrink film represents a large price advantage over traditional packaging methods.

  • The low volume and weight of shrink film saves additional storage.
  • Shrink film protects from humidity, dust and dirt.
  • Shrink film is perfect for multi-packs, which offer value and cost savings to packagers and consumers alike.
  • Shrink packaging allows for storage in the refrigerator.
  • Printed shrink film is an attractive alternative to traditional packaging methods and can help increase brand awareness and loyalty.
  • Up to 75% less shrink material is needed compared to corrugated products.
  • Products wrapped in shrink film are tamper-evident.
  • For a given packaging requirement, no other form of packaging uses less resources or energy.
  • Shrink film equipment uses less floor space.

“LE Gold shrink film from Clysar is the best choice I’ve found for wrapping Houdini gift baskets. Clysar has a better appearance than any competitor—and with gift baskets—that’s very important. I need shine, sparkle, gloss, plus the strength to hold different items together for an upscale first impression. Clysar does it well.
