Blown Stretch Film for Tough, Puncture-Resistant Load Containment

Blown stretch film is made by inflating molten resin into a tall bubble that cools slowly in the air. That process builds a film with high puncture resistance and strong holding force, the choice for sharp, heavy, or irregular loads that standard film struggles to contain.

How Blown Stretch Film Is Made

The slow, air-cooled bubble is what separates this film from chill-roll grades. The resin has time to align in two directions, which adds toughness across the whole roll.

ExtrudeMolten resin flows through a round die.
InflateAir expands it into a tall, thin bubble.
Cool slowlyThe bubble cools in open air as it rises.
Collapse and windThe film is flattened, trimmed, and rolled.

Why Blown Stretch Wrap Holds Difficult Loads

Blown stretch wrap trades some clarity for strength. These are the properties that matter on demanding lines.

Puncture Resistance

Film stays intact over corners, edges, and protruding parts.

Strong Holding Force

Tension holds loads tight through braking, turns, and transfers.

Durability Over Time

Film keeps its grip through long storage and multiple handling points.

Loads That Call for Blown Stretch Film

Metal parts, profiles, and coils with sharp edges
Lumber, pipe, and building materials
Heavy or uneven loads that shift in transit
Loads stored outdoors or shipped long distances
Mixed pallets with protruding corners

If appearance and barcode scanning through the film matter more than toughness, compare our cast stretch film, which offers higher clarity and a quieter unwind.

Engineering Support for Blown Film Programs

As blown stretch film manufacturers, we set gauge, cling, and roll format around the loads you actually ship. Our team reviews breaks, punctures, and load shifting, then adjusts the specification instead of simply adding more film.

Hand and machine roll formats
Gauge matched to load weight and edges
One-side cling options to reduce load-to-load sticking
Recurring delivery from our 2 distribution centers

Blown Stretch Film FAQs

Short answers about blown film performance.

Why is blown stretch film hazier than other films?

The slow cooling that adds toughness also creates a slightly hazy finish. Labels stay readable, though scanning through the film can be harder.

Is blown stretch wrap louder to unwind?

Yes, it usually unwinds with more noise. On most lines this has little effect on wrapping speed.

Does blown film cost more per load?

The roll often costs more, but tough loads may need fewer wraps and fewer rewraps, which can lower the cost per load.

Can I apply blown stretch film by hand?

Yes. Blown grades are produced in manual and machine formats, so mixed operations stay on one film type. For manual stations, compare our hand stretch film rolls.

Does blown film offer one-side cling?

Yes, one-side cling grades are available. The outer layer stays smooth, so wrapped pallets slide past each other in trailers and racks with less tearing.

How do I pick the right blown film gauge?

Share your load weight, edge profile and wrapper type. Our engineers test samples on comparable loads and recommend the lightest gauge that holds securely.
