In the world of packaging, the materials you choose can make a big difference in how well your products are protected during storage and transit. One material that plays a crucial role in many packaging applications—especially stretch wrap—is LLDPE, or Linear Low-Density Polyethylene.
Let’s break down what LLDPE is, why it matters, and how it works with stretch film to improve pallet stability, reduce waste, and save costs.
What is LLDPE?
Linear Low-Density Polyethylene (LLDPE) is a type of plastic made through a polymerisation process that gives it a more linear molecular structure than traditional LDPE (low-density polyethylene). This structure gives LLDPE several key advantages:
- Flexibility and strength – LLDPE is tough, with excellent resistance to punctures and impact. It’s ideal for wrapping irregularly shaped or heavy items.
- Stretchability – Thanks to its structure, LLDPE can stretch without tearing, making it perfect for stretch film applications.
- Chemical resistance – It holds up well against a wide range of chemicals, adding versatility across industries.
- Clear and glossy finish – LLDPE can be manufactured to be transparent and shiny, which is useful for packaging where presentation matters.
LLDPE is widely used in products like plastic bags, agricultural films, and flexible containers—but it really shines in stretch film.
What is stretch wrap?
Stretch wrap (also known as stretch film) is a thin plastic film—often made from LLDPE—that is used to wrap, secure, and stabilise items on pallets during transport and storage.
Why is stretch wrap so popular?
- Improved load stability – It helps keep products tightly secured, reducing movement and minimising damage.
- Cost-effective protection – It cuts down the need for other packaging materials, saving time and money.
- Versatile applications – From food to industrial goods, stretch wrap can be used across countless industries.
- Tamper evidence – Once wrapped, it’s easy to spot if a pallet has been interfered with.
How LLDPE and stretch wrap work together
LLDPE is the go-to material for making high-performance stretch films. Its unique blend of stretch, strength, and durability means it can tightly conform to pallet loads without breaking or snapping under tension. This makes it a reliable, efficient packaging solution for businesses large and small.
For example, high-quality stretch films made from LLDPE can be used with powered pre-stretch pallet wrappers, reducing the amount of plastic required per pallet wrap and improving wrapping consistency.
Why it matters for your business
Understanding LLDPE helps businesses choose the right type of stretch film for their needs. The better the film, the less waste you generate, the more stable your pallets, and the lower your shipping damage risk.
If you're aiming to improve your packaging processes, reduce film use, or switch to a more efficient system, knowing how LLDPE works is a smart place to start.
