Stretch Hood
A stretch hood solutions that fits your packaging
Packaging protects a product. But what protects the package? That’s a big question as e-commerce and cargo shipments drive more and more products around the world. Unsaleable or returned goods due to transport damage cost millions of dollars each year. Finding a better way to keep shipments safe and secure benefits the entire value chain.
Stretch hood protection
Stretch hood packaging encloses shipping pallets in a single sheath of high-performance film, top to bottom. Stretch hood packaging offers five-sided protection: The top is closed to ensure products stay dry and to provide protection against ultra-violet radiation. The four side panels are also solid and further reduce the risk of weather damage, while providing exceptional stability and holding force.
The stretch hood film extends below the bottom edge of the pallet, tightly wrapping around the bottom edge to completely secure the load. The result? Products stay put on their pallets.
Benefits of stretch hood films across the value chain

Resins for stretch hood film manufacturers
At Dow, we’ve been working with industry experts and developing films for stretch hood for close to 30 years. We even have our own stretch hood line and transportation packaging test labs at Pack Studios Freeport in Texas. You can trust our portfolio of resins and our suggestions for how to mix and match them for the best results.
Take for example, ELITE™ AT Enhanced Polyethylene Resins, an ethylene vinyl acetate (EVA) free solution for stretch hood films offering unique holding force, elasticity recovery, optics and toughness. In addition, we offer DOWLEX™ GM LLDPE Resins and VERSIFY™ Plastomers & Elastomers for stretch hood films.
Suggested stretch hood structures deliver excellent elasticity for films that conform tightly to the contours of the packaged goods. Excellent toughness and puncture resistance are key. Good tear resistance is another advantage. You may even achieve holding force at lower densities and be able to downgauge for lower raw material costs and CO2 reductions.
The stretch hood process itself offers many advantages:
