When choosing between cast and blown stretch film, the differences go beyond just price. Each type has its own unique characteristics that affect how it performs on the warehouse floor and out in the field. From how well the film holds a load, to how much you can stretch it, to how noisy it is when applying, these details can make a big impact on both efficiency and product protection. The table below highlights the key performance factors that set cast and blown stretch films apart so you can quickly see which option best fits your operation.

Cast stretch film is made through a process called cast extrusion, which is faster and more efficient than the blown method. In simple terms, it costs less to produce—and those savings usually get passed right along to you.

The Price Advantage: On average, cast film runs about 10–20% cheaper than blown film. That may not sound like much at first, but if your facility goes through rolls every day, that difference adds up quickly over the course of a year.

Clarity and Convenience: One of the standout benefits of cast film is its high transparency. You can clearly see product labels, barcodes, and SKUs underneath, which makes scanning and identifying pallets a whole lot easier.

Quieter Application: Unlike blown film, which can be noisy when you pull it off the roll, cast film is smooth and quiet. That might seem like a small detail, but in a busy warehouse it makes a noticeable difference—especially if your team is wrapping pallets all day.

Best Fit: Cast stretch film is the go-to for lightweight, uniform loads where cost savings matter more than maximum strength. If you’re wrapping standard pallets headed for indoor storage or short-distance shipping, cast film gives you everything you need without the higher price tag.

For many operations, cast stretch film ends up being the everyday choice—budget-friendly, easy to work with, and reliable for most pallets that don’t require heavy-duty protection.

Cast stretch film is made using a process called cast extrusion, which is faster and more efficient than the blown method. Because it’s easier to produce, it generally comes at a lower cost for buyers.

The Price Advantage: Cast stretch film usually runs 10–20% cheaper than blown film. That may not sound like a big gap, but if you’re using multiple rolls every day, those savings stack up fast—potentially cutting thousands off your annual packaging spend.

Clarity You Can Count On: One of the biggest perks of cast film is its high transparency. You can easily see labels and scan barcodes without peeling back the wrap, which keeps warehouse operations moving smoothly.

Quiet and Easy to Use: Cast film also unwinds quietly, making it a lot more pleasant to work with indoors compared to the loud crackle of blown film. For teams wrapping pallets all day long, that lower noise level can really improve the work environment.

Best For: Cast stretch film is ideal for light, uniform pallet loads—the kind of everyday shipments where you don’t need extreme puncture resistance, but you do want consistent performance at a lower price.

For many warehouses, cast stretch wrap becomes the go-to, everyday choice—affordable, easy to handle, and reliable for standard pallet loads.

When you stack cast and blown stretch film side by side, the differences really come into focus. Here’s how they compare in everyday use:

•  

• Average Price: Cast stretch film is usually 10–20% less expensive than blown. That lower upfront cost makes it the budget-friendly choice for most day-to-day wrapping. Blown film, on the other hand, tends to run 10–20% more per roll, reflecting its tougher performance.

•  

• Clarity: Cast film offers high transparency, so it’s easy to read labels or scan barcodes right through the wrap. Blown film comes out cloudier, which can make it harder to identify what’s inside at a glance.

•  

• Puncture Resistance: Cast film handles regular loads well, but it’s only moderately resistant to sharp edges. Blown film, however, is built for abuse—it’s much stronger and more puncture-resistant, which is why it’s trusted for irregular or heavy loads.

•  

• Load Holding Power: Cast provides good stability for standard, uniform pallets. Blown film has exceptional holding force, keeping even tricky loads tight and secure through long hauls.

•  

• Noise Level: Cast film is quiet during use, making it a lot easier on the ears in a busy warehouse. Blown film is noisier when unwinding, something to keep in mind if your team wraps pallets all day long.

•  

• Best Use Case: Use cast film for light, consistent pallets where cost savings matter most. Choose blown film for heavy, sharp, or unstable pallets where strength and protection outweigh the higher price.

In short: Cast stretch film keeps costs low for everyday wrapping, while blown stretch film delivers extra strength and peace of mind when your loads are tougher to manage.

The real cost of stretch wrap goes far beyond the price tag on each roll. What really matters is how well it protects your products once they’re on the move. A cheaper film that doesn’t hold up can end up costing far more in product damage, freight claims, or wasted labor.

•  

• Cast Stretch Film is the smart choice when you’re wrapping lighter, uniform pallets and keeping an eye on your packaging budget. It’s affordable, easy to apply, and gets the job done without over-engineering.

•  

• Blown Stretch Film shines when you’re dealing with heavy, uneven, or sharp-edged loads. Even though the roll itself costs more, it offers superior strength and holding power that can prevent pallets from shifting, tearing open, or arriving damaged.

Many purchasing managers and warehouse supervisors discover that the best strategy isn’t an “either/or” decision—it’s a blend of both. By using cast film for the majority of everyday pallets and reserving blown film for the tough loads, companies often strike the perfect balance between cost savings and product protection.

At the end of the day, it’s not just about how much you spend on stretch wrap—it’s about how much it saves you in the long run.
