Stretch Film Basics
What Is Stretch Film?
Otlolla filimi — also called stretch wrap or pallet wrap — is a linear low-density polyethylene (LLDPE) film that is stretched around a load and then released. As the film tries to return to its original length, it generates the force that holds the load together. Two properties decide how a film performs:
Elastic Recovery
The film’s ability to pull back toward its original length after stretching. This is what creates containment force — the grip that stops a pallet from shifting or racking in transit.
Khomarela
Surface tack that makes successive layers bond to each other with no adhesive, tape or heat. Cling can be built into one side (one-sided cling) or both (two-sided cling) depending on the application. Because LLDPE adds only a few hundred grams per pallet, it delivers high containment force at a fraction of the weight and cost of corrugated board, strapping or heat-shrink film — which is why it is the standard method for unitizing palletized cargo. Our films run from 12 µm to 35 µm (48–140 tekanyo) with pre-stretch rates up to 350%, in one-sided or two-sided cling.

Where Stretch Film Is Used
Pallet Unitizing
The core application. Wrap from the bottom up with roughly 50% koelana, lock the film to the pallet base rather than the cartons, and run 3–5 bottom wraps to anchor the load. This is what stops cartons from racking or sliding in transit.
Carton Bundling
Band loose cartons or multi-packs into one handling unit without tape or strapping. Bundling film is usually thinner (12–20 µm) because containment force matters more here than puncture resistance.
Reels, Rolls & Long Goods
Carpet rolls, wire coils, pipe, profiles and timber can be wrapped end to end to stop the outer layers unspooling and to protect surfaces from scuffing in handling.
Shelf & Storage Protection
A single light layer keeps cartons clean, sealed and dust-free during warehousing and shelf stocking.
Container & Export Transit
For long-haul or containerized freight, add a top sheet or hood over the wrapped pallet for dust and moisture protection. Use UV-inhibited film if the load will sit outdoors for more than a few weeks.

Why It Works
Benefits of Stretch Film for Pallet Wrapping
Colored Film Options · Load ID & Concealment
Reduced Shipping Damage
Containment force holds the load as a single unit, so cartons don’t rub or shift against each other in transit. Most transit damage on palletized freight comes from load movement, not from external impact.
UV Protection for Outdoor Storage
UV-inhibited formulations hold up for 6–12 months outdoors. Standard film without UV inhibitor chalks and loses tensile strength after a few weeks in direct sun.
Theft & Pilferage Deterrence
Black opaque film hides load contents entirely, and any cut or tear is visible on inspection — which removes the opportunity for quick pilferage in transit or yard storage.
Dust & Moisture Barrier
A wrapped pallet is sealed on five sides. Add a top sheet or hood for full coverage in container or open-yard storage.
Lower Cost per Wrapped Pallet
At pre-stretch rates up to 350%, one metre of film covers roughly 4.5 metres of pallet — so film consumption and cost per load drop significantly versus non-pre-stretched or hand-applied film.
Lower Capital Cost Than Alternatives
A turntable or rotary arm wrapper costs a fraction of a shrink tunnel or automated strapping line, needs no heat source, and consumes no strapping.

How Stretch Film Is Made
Cast Extrusion
Resin is melted and forced through a flat linear die onto large-diameter chilled rollers, where it quenches rapidly. Fast cooling produces a film with excellent optical clarity, uniform gauge, quiet unwind and two-sided cling. Cast accounts for roughly 70–80% of stretch film produced worldwide, and is the default choice for automated wrapping and barcode scanning.
Blown Extrusion
Resin is extruded through a circular die and inflated into a vertical bubble, which is then cooled slowly as it rises. The slower cooling yields a tougher film with higher puncture resistance and tensile strength — but with slightly hazy clarity, audible unwind and one-sided cling. Blown is chosen for heavy, sharp-edged or irregular loads.
Multilayer Construction
Both processes can run 3, 5 kapa 7 layers on a co-extrusion line. Each layer is formulated for a different job — cling on one surface, slip on the other, puncture resistance in the core — so the film can be tuned for a specific load without changing the base resin.
Which to Choose
Use cast for uniform loads on automated equipment where clarity and quiet running matter. Switch to blown when loads are heavy, sharp or irregular and puncture resistance is the priority.

Temohisiso ea Setsebi
Match the Gauge to the Load, Not the Price List
Micron choice drives landed cost per pallet more than any other buying decision. A film that is one gauge too heavy quietly taxes every wrap you make; one gauge too light shows up as load failures, rewraps and claims.
- Uniform, light loads run well on 12–15 µm pre-stretch grades
- Sharp-edged or heavy loads need 20–25 µm and higher puncture resistance
- Buy on measured containment force, not on film width alone
- Trial two gauges side by side on your worst pallet before committing volume

Standard specifications start at 1 phalete, kapa 500 kg for jumbo rolls. Fully customized thicknesses, colors or printed cores typically start at one full 20ft container. Lead time is 7–15 business days depending on volume and how much customization is involved.
12 µm to 35 µm (48 ho 140 tekanyo). Machine-grade film runs pre-stretch rates from 200% up to 350% on high-speed automated pallet wrappers, which cuts film consumption and cost per pallet. Hand film runs 12–30 µm (48–120 tekanyo) with 100–150% standard stretch.
Ee. Full OEM/ODM across film widths from 50 mm to 2,000 mm, roll lengths, core sizes (1.5″, 2″, 3″), plus custom branding and printed paper cores. We also make black and colored film for cargo concealment, and UV-inhibited formulations rated for up to 12 months of outdoor storage.
Our cold-resistant LLDPE formulas hold elastic recovery and cling down to −25 °C (−13 °F). They resist embrittlement, stress cracking and load shifting in blast freezers, refrigerated distribution centers and high-bay AS/RS warehouses.
Cast film is made on a flat die: superior optical clarity, uniform gauge, quiet unwind and two-sided cling. It is the cost-effective default for automated wrapping and barcode scanning. Blown film is made through a vertical bubble: higher puncture resistance and tensile strength, one-sided cling, slightly hazy. Use blown for heavy, sharp or irregular loads.
Unitizing cartons onto a pallet so they travel as one stable load, bundling loose items, protecting surfaces from dust and scuffing, and providing visible tamper evidence. It is standard in warehousing, freight and export shipping.
Cling film (as used in food wrapping) is a thin film that adheres to surfaces on contact and has almost no elastic recovery. Stretch film is thicker and engineered to be stretched under tension — its elastic recovery is what generates the containment force that holds a load together. They are not interchangeable in industrial pallet wrapping.
Unopened rolls stored in a cool, dry place away from direct sunlight typically keep full performance for 12–24 months. Hang ha e sebelisoa, a properly wrapped load holds containment force for the duration of normal transit and storage — but UV exposure is the limiting factor outdoors, which is why UV-inhibited film is specified for loads sitting outside more than a few weeks.
LLDPE stretch film softens around 90–100 °C and melts at roughly 110–125 °C, depending on the resin grade and metallocene content. In normal use this is not a concern: warehouse and transit temperatures stay far below that range. The practical heat limit for storage is about 40 °C — above that, film can start to block (layers sticking together) on the roll and lose cling performance.
