Types of Stretch Film: A Breakdown of the Different Types and Their Benefits

If you’ve ever stood in front of a packaging supplier’s catalogue and wondered why there are a dozen different stretch films to choose from, you’re not alone. “Stretch film” isn’t one product — it’s a category, and picking the wrong type can mean wasted film, damaged loads, or paying for performance you don’t actually need. 

Here’s a practical breakdown of the main types of stretch film on the market, and what each one is actually good for. 

1. Cast Stretch Film

Cast film is made by extruding molten resin through a flat die and rapidly cooling it on chill rollers. This process gives cast film its signature characteristics: 

• High clarity — easy to read barcodes and labels through the film 

• Quiet unwind — no loud “cracking” noise on the dispenser, which matters in noise-sensitive environments 

• Excellent cling and puncture resistance 

• Softer, easier tear for hand application 

Best for: Hand wrapping, general-purpose pallet loads, and operations where noise levels or product visibility matter. 

2. Blown Stretch Film

Blown film is produced by extruding resin through a circular die and inflating it into a bubble before cooling. This gives it a different performance profile: 

• Higher tear and puncture resistance 

• Better load-holding force and memory — it “grips” the load and holds tension over time 

• More elasticity, which allows for higher stretch ratios 

Best for: Heavier, irregular, or sharp-edged loads, and machine-wrapping applications where maximum containment force is the priority. 

3. Hand Film

Hand film is designed specifically for manual wrapping, usually mounted on a handheld dispenser. It typically comes in narrower widths (12″-20″) and is engineered for comfort and control rather than maximum stretch. 

Benefits: 

• Easier on the operator’s hands and arms over a full shift 

• Available in extended-core options that reduce the effort needed to stretch the film during application 

• Good for low-volume or irregular wrapping tasks where a machine isn’t practical

Best for: Low-volume operations, irregular loads, or as a backup to machine wrapping. 

4. Machine Film (Pre-Stretch Film)

Machine film is designed to run on power pre-stretch or turntable wrap systems, which mechanically stretch the film before it’s applied to the load. Because the machine does the stretching, this film is engineered for high stretch ratios (commonly 200%-300%+). 

Benefits: 

• Significant cost savings per pallet — more film footage delivered from less raw material 

• Consistent tension and containment force, since the machine — not an operator’s arm — controls the stretch 

• Reduced film usage and waste compared to hand wrapping the same loads 

Best for: Medium-to-high volume operations running automatic or semi-automatic wrap equipment. 

A Quick Word on Microns 

One thing that trips a lot of operations up: film thickness, or “gauge,” measured in microns. 

For years, 23 micron has been the go-to standard for machine film, and a lot of specs have simply stayed there — not because it’s been tested against anything better, but because it’s what’s always been used. Thicker felt safer, so nobody questioned it. 

That’s starting to shift. As resin technology has improved, high-performance grade films are increasingly able to deliver the same or better containment force, puncture resistance, and holding power at a lower micron gauge. In practice, that means: 

• Less plastic used per pallet, simply by right-sizing the gauge to what the load actually needs 

• Lower film cost per pallet, since a thinner high-performance film often costs less overall than a thicker standard film, even though it’s a higher-spec product 

• No compromise on load protection, provided the film has actually been engineered — and tested — to perform at the lower gauge 

The catch is that not all thin film is created equal. Dropping micron on a standard-grade film without upgrading the resin will cost you load containment. The gains only show up when the lower gauge is paired with a genuinely higher-performance film — which is exactly why it’s worth checking your current spec against what’s now available, rather than assuming 23 micron is still the right answer. 

5. Coloredand UVI (UV-Inhibited) Film 

Standard stretch film is clear, but colored and UVI variants serve specific purposes: 

• Colored film (black, blue, green, etc.) is used to conceal product from view — useful for high-value goods, confidential shipments, or brand protection during transit and storage. 

• UVI film is treated to resist UV degradation, making it suitable for pallets that will sit outdoors or in direct sunlight for extended periods without the film becoming brittle.

Best for: Security-sensitive shipments, outdoor storage, or long-term/seasonal storage applications. 

6. Vented (Micro-Perforated) Film

Vented film has small perforations that allow airflow through the wrap while still containing the load. 

Benefits: 

• Allows produce, plants, or other items that need ventilation to breathe during transit 

• Reduces condensation buildup inside the wrap 

Best for: Fresh produce, nursery/greenhouse goods, and other temperature- or moisture-sensitive products. 

7. Recycled and Sustainable Stretch Film

Recycled stretch film incorporates post-consumer or post-industrial recycled (PCR/PIR) resin into the film, without sacrificing stretch performance or load containment when properly engineered. 

Benefits: 

• Supports sustainability goals and can help meet customer or regulatory reporting requirements 

• Reduces reliance on virgin resin 

• Modern recycled films are increasingly matched to virgin-film performance, so the switch often doesn’t require any change in wrap equipment or technique 

Best for: Operations under pressure — internally or from customers — to reduce packaging’s environmental footprint, without compromising load protection. 

Choosing the Right Film for Your Operation 

There’s no single “best” stretch film — the right choice depends on: 

• Load type and weight (sharp edges, irregular shapes, heavy vs. light loads) 

• Wrapping method (hand vs. machine) 

• Environment (indoor vs. outdoor, humidity, UV exposure) 

• Business priorities (cost per pallet, sustainability targets, security/confidentiality needs) 

Getting the film-to-application match right isn’t just about performance — it’s often where the biggest, easiest cost savings in a packaging operation are hiding. If you’re not sure which type fits your setup, a quick load and equipment review is usually all it takes to find out.
