Machine-Grade LLDPE Pallet Wrap — Cast & Blown
Machine Stretch Film for Automatic Pallet Wrappers
Stretch It First. Pay For It Once.
Machine stretch film is engineered to run on powered wrapping equipment — turntable, rotary-arm and ring-type wrappers — where the machine stretches the film to a set ratio before it ever touches the load. Run at 200–300% pre-stretch, one kilogram of film covers materially more pallet surface than hand film of the same gauge: that is where the cost per wrapped pallet is won.
Introduction
Machine Stretch Film Built for Automatic Wrappers
Vistech machine stretch film is a 5-layer LLDPE film produced by cast or blown extrusion for turntable, rotary-arm and ring-type pallet wrappers. Standard gauges run 17–23 µm for general freight and 23–35 µm for heavy or sharp-edged loads. Run at 200–300% pre-stretch, one roll covers materially more pallet surface per kilogram than hand film of the same gauge — that is where the cost per wrapped pallet is won. Widths are supplied from 500 mm up to 2,030 mm, on a 76 mm (3 in) core.
Machine stretch film is an LLDPE pallet wrap engineered to run on powered wrapping equipment rather than by hand. It is applied by turntable, rotary-arm or ring-type wrappers that stretch the film to a set ratio before it touches the load; the film then relaxes and holds the pallet in compression. Because the machine controls the stretch, machine film can be run at 17–23 µm where hand application of the same load would need a heavier gauge — this is the main reason high-volume operations switch. Three variables decide the specification: load weight and profile, the pre-stretch ratio your carriage can hold, and whether the pallet will be stored outdoors.

Wide web film is any machine roll wider than 500 mm (20 in). We supply up to 2,030 mm (80 in) in a single piece. Wide web pays off when a load is tall, wide or irregular enough that a 500 mm roll would need many overlapping passes — fewer passes means less film in the overlap zone and a shorter wrap cycle. It is not automatically cheaper: if your load profile fits a standard spiral pattern, a 500 mm roll usually gives a lower cost per pallet. Send us pallet dimensions and wrap pattern and we will run the comparison.
Pre Stretched Machine Stretch Film
Supplied pre-stretched at the factory — lighter gauge with the holding force already built in.
Color Tinted Machine Stretch Film
Tinted machine grades for load identification, inventory colour-coding and brand matching.
Opaque Machine Stretch Film
Opaque films that conceal the load, protect against UV and shield high-value pallets in transit.
Airflow Machine Pallet Wrap
Engineered for ventilated loads — produce, flowers and frozen goods that must breathe through the wrap.
Gauge Selection
When To Use Which Gauge
Match the gauge to the load, not to the price list. These are the starting points we use when specifying a wrap programme — the final number is set by your pre-stretch ratio and transit conditions.
| Load type | Recommended gauge | Why |
|---|---|---|
| Bagged goods, tissue, paper products | 17–20 µm | Load compresses; film needs cling and coverage, not puncture resistance |
| Standard cartons on a uniform pallet | 20–23 µm | Balanced containment force at 200–250% pre-stretch |
| Buckets, drums, sharp-edged parts | 23–30 µm | Edge puncture risk; consider blown grade |
| Building materials, timber, tile | 25–35 µm | High load weight and abrasive corners |
| Outdoor storage over 30 days | 23 µm + UV-stabilised | Standard LLDPE loses elasticity under prolonged UV |

Why Partner With Vistech
Your Trusted Industrial Stretch Film Manufacturer
Our pallet wrap provides the best possible pallet security for the goods. Outstanding film bonding and the highest level of stability are made possible by excellent adhesion qualities. The wrapping’s smooth exterior prevents it from clinging to adjacent pallets, ensuring a seamless loading operation.
All Vistech machine stretch films are made from a single-polymer LLDPE structure, which keeps them in the polyethylene recycling stream (resin identification code 4) rather than in mixed-material waste. We do not add fillers or non-PE layers that would break that stream. Whether a given roll is actually recycled depends on the collection and sorting infrastructure at the destination — we can supply a material declaration per shipment so your waste contractor can classify it correctly.
The Advantage of Our Machine Stretch Film
Higher Yield Per Kilogram
At 300% pre-stretch, 1 kg of film covers roughly 3× the pallet area it would at zero stretch.
Gauge Consistency
Thickness held to ±5% of average (ISO 4591), so the wrap programme does not need re-tuning between rolls.
Puncture Resistance at the Corners
Blown grades available where carton edges or protruding parts are the failure point.
One-Side Cling
Layers bond to each other, but the outside of the wrap does not stick to neighbouring pallets on the truck.
Quiet Unwind
Cast grades run quieter than blown, which matters on lines running beside pick-and-pack.
Longer Rolls
Extended roll lengths cut core-change downtime on high-throughput lines.

The Wrapping Cycle
How Machine Stretch Film Works
Four things happen between the reel and the finished pallet — and each one is controlled by the wrapper, not the operator’s strength. That is the whole point of machine film: the same stretch ratio, the same containment force, on pallet number one and pallet number one thousand.
Pre-Stretch
The wrapper carriage runs the film between two rollers at different speeds, stretching it to a set ratio — typically 200–300% — before it ever touches the load. Film is paid out by length, so stretching it first is what makes one kilogram cover three times the area.
Application Under Tension
The stretched film is applied to the pallet under controlled tension. The operator sets this on the machine; too little leaves a loose wrap, too much crushes light cartons.
Relaxation and Containment Force
Once applied, the film tries to return towards its original length. That recovery is what pulls the load inward — the containment force that stops cartons shifting in transit. It is highest in the first hour and then decays, which is why wrap patterns matter more than raw thickness.
Layer-to-Layer Cling
A cling layer on one face bonds each pass to the previous one, so the wrap behaves as a single shell rather than loose bands. The outer face stays non-cling, so pallets do not stick together on the truck.
Application Under Tension — Film Drawn From The Roll Onto The Load
Our Advantage
Rigorous Laboratory Testing for Polymer Film Optimization
Continuous quality control processes within both our production plants validate the technical specification of our thermoplastic packaging materials. Our automated testing protocols analyze the physical properties of our machine stretch wrap, specifically mapping tensile strength, puncture resistance, multi-directional stretch force, interlayer cling, tear resistance, and ultimate elongation thresholds. These scientific evaluations generate quantifiable, repeatable metrics that guarantee stable load retention and zero material failure, reinforcing our position as a certified premium stretch film manufacturer.
Process Choice
Cast vs Blown Machine Stretch Film
Both start from the same LLDPE and end on the same 76 mm core — the difference is how the web is formed, and it shows up in clarity, consistency and noise on your line.
| Cast | Blown | |
|---|---|---|
| How it is made | Molten polymer extruded onto a chilled roller | Polymer blown into a bubble, then collapsed and wound |
| Clarity | High — labels readable through the wrap | Hazy |
| Gauge consistency | Tight — ±5% typical | More variation |
| Puncture resistance | Good | Higher — preferred for sharp edges |
| Unwind noise | Quiet | Noticeably louder |
| Typical share | Dominant for automatic wrapping | Roughly a quarter of machine-grade demand |

Applications
Diverse Application Fields We Serve
Always choose machine stretch films based on the precise needs of the task. Machine stretch films are especially susceptible to delicate, light, and unsteady loads. As there is no better way to represent them, various uses need distinct film widths and thicknesses. Regardless of the standards and criteria of your application, we will help and direct you through the procedure. No matter the circumstance, we offer stretch films for practically all sorts of machinery — for both fully automatic and semi-automatic machines.

FAQ
FAQ for Machine Stretch Film
An LLDPE pallet wrap made to run on powered wrapping equipment. It is stretched by the machine before it touches the load, which is why it can be used at a lighter gauge than hand film.
17–20 µm for light, compressible loads such as bagged goods and paper; 20–23 µm for standard carton pallets; 23–30 µm where edges are sharp; 25–35 µm for heavy building materials.
Up to 300%. Most lines settle at 200–250%, which is set by what your carriage can hold, not by the film.
Cast for clarity, gauge consistency and quiet unwind. Blown where puncture resistance matters, such as sharp or irregular loads.
If your machine takes a 76 mm core and machine-grade film, yes. Tell us the wrapper make and model and we will confirm gauge and pre-stretch range.
76 mm (3 in) as standard; 50 mm (2 in) is available on request.
500 mm as standard, plus 750 mm and 1,520 mm, and wide web up to 2,030 mm (80 in) in a single piece.
Yes. Black for concealment and UV protection, and UV-stabilised grades for pallets stored outdoors beyond a few days.
MOQ 500 rolls, lead time 7–15 days after order confirmation. Custom widths and printed film take longer.
12 months from production date, stored indoors below 30 °C and away from direct sunlight. UV exposure before use is the main cause of premature loss of elasticity.
