Stretch wrap holds a load using its own tension and needs no heat. Shrink wrap is applied loosely, then heated so it shrinks tight around the product. They sound similar and are often confused, but they are different products for different jobs. For securing boxes on a pallet, you want stretch wrap.
The quickest way to remember it: stretch wrap stretches around a load, shrink wrap shrinks onto a product. One uses tension, the other uses heat.
How Stretch Wrap Works
Stretch wrap, also called pallet wrap or stretch film, is a stretchable plastic film. You wrap it around a load and it grips using its own elasticity. As you apply it, the film stretches and then tries to pull back, and that retained tension holds the load together.
No heat, no equipment beyond a dispenser or your hands, and no special skill. That simplicity is why stretch wrap is the standard way to secure palletised loads across warehousing and logistics.
How Shrink Wrap Works
Shrink wrap is a different film that behaves the opposite way. You place it loosely over or around the product, then apply heat with a heat gun or a heat tunnel. The heat makes the film shrink, pulling it tight against the product’s shape.
Because it shrinks to the exact shape of what it covers, shrink wrap gives a tight, contoured finish. But it needs a heat source and more setup, and it is generally used to wrap individual products or small bundles rather than to secure a full pallet.
The Key Differences
Heat. Stretch wrap needs none. Shrink wrap needs a heat source to work. This is the fundamental difference, and it drives all the others.
How they hold. Stretch wrap holds by tension. Shrink wrap holds by shrinking tight to the shape of the product.
Equipment. Stretch wrap needs at most a dispenser. Shrink wrap needs a heat gun or heat tunnel.
Typical use. Stretch wrap secures loads on pallets and bundles awkward items. Shrink wrap gives a tight, sealed finish around individual products, multipacks and some retail packaging.
Finish. Stretch wrap leaves a wrapped, layered look. Shrink wrap leaves a smooth skin tight to the product.
Speed for palletising. Stretch wrap is quicker and simpler for pallets because there is no heat step.
Which One Do You Need?
For securing boxes and goods on a pallet, you want stretch wrap. It is faster, needs no heat, and is designed for exactly this job. This covers the vast majority of warehouse and logistics wrapping.
Choose shrink wrap when you specifically need a tight, contoured, sealed finish around a product or small bundle, and you have the heat equipment to apply it. Think of tightly wrapping a single item for retail, or sealing a multipack. It is the wrong tool for securing a full pallet, where the heat step and setup make no sense.
If your job is holding a load together on a pallet, stretch wrap is the answer nearly every time. If your job is sealing a tight skin around a product, that is where shrink wrap belongs.
Cost and Practicality
The two also differ in what they cost to run. Stretch wrap needs no power and, at most, a low-cost dispenser, so there is no heat step, no energy for a heat gun or tunnel, and no waiting for equipment to warm up. Shrink wrap carries more overhead: equipment to buy and maintain, energy to run, and a heating step for each item. That overhead is worth it only where the sealed finish is genuinely needed. For palletising, stretch wrap is cheaper and simpler.
Related Products
Two other load-securing methods come up in the same conversation. Strapping uses plastic or steel bands tensioned around a load, often used alongside stretch wrap on heavy or rigid loads for extra security. Pallet netting is a stretchable net rather than solid film, used where a load needs airflow, such as some produce. For most palletised goods, stretch wrap remains the default, with strapping added when a heavy or rigid load needs extra hold.
Frequently Asked Questions
Is stretch wrap the same as shrink wrap?
No. Stretch wrap holds a load with its own tension and needs no heat. Shrink wrap is heated so it shrinks tight around a product. They are different products for different jobs.
Can I use stretch wrap instead of shrink wrap?
For securing pallets, yes, stretch wrap is the right choice. For a tight, sealed skin around an individual product, you need shrink wrap and the heat equipment to apply it. They are not interchangeable for that finish.
Does stretch wrap need heat?
No. Stretch wrap works purely by stretching and holding tension. Only shrink wrap needs heat.
Which is cheaper to use, stretch or shrink wrap?
For palletising, stretch wrap is cheaper and simpler because there is no heat equipment, energy or heat step. Shrink wrap makes sense only where you specifically need its sealed finish.
What about strapping and pallet netting?
Strapping adds extra security on heavy or rigid loads and is often used alongside stretch wrap. Pallet netting is used where a load needs airflow. For most palletised goods, stretch wrap is the default.
Conclusion
Stretch wrap and shrink wrap solve different problems. Stretch wrap secures loads on pallets using tension, with no heat and minimal equipment, which is why it is the standard for warehouse and logistics wrapping. Shrink wrap gives a tight, sealed finish around individual products but needs heat to work. For holding a load together on a pallet, stretch wrap is almost always the right choice.
