Machine Stretch Film Thickness: Match Micron to Pallet Load

30 October 2026

Westside Packaging Systems explains machine stretch film thickness for pallet loads, helping Melbourne businesses compare micron ranges and key film types.

Machine stretch film thickness is one factor that affects pallet stability, puncture resistance, film consumption and wrapping cost. A thicker film may provide added durability, but it is not automatically the best choice for every application. The right specification depends on the pallet profile, film construction, wrapping equipment and conditions the load will encounter.

How Does Machine Stretch Film Thickness Affect Pallet Loads?

Film thickness is measured in microns, with one micron equal to one-millionth of a metre. As the micron rating increases, the unstretched film becomes thicker, which can improve durability when wrapping abrasive or uneven pallet loads.

Micron alone does not determine how well a film will perform. Resin formulation, cast or blown construction, stretch capability and the machine’s settings also affect puncture resistance, containment and the amount of film required per pallet.

Match the Micron Range to the Pallet Profile

Pallet weight matters, but shape, stacking quality, sharp edges and centre of gravity may have a greater effect on film performance. Westside Packaging Systems stocks machine-grade cast stretch film in several micron options, but the following ranges should be treated as starting points for testing rather than fixed weight limits.

• 15 or 17 micron cast film: These thinner films may suit stable carton loads and reduce roll changes, but film use per pallet should be tested.
• 20 micron cast film: This option can provide a useful starting point for regular warehouse pallets with uniform layers and no significant protrusions.
• 23 micron cast film: The added thickness may suit denser, less uniform or more demanding pallet profiles that need greater durability during handling.
• 25 micron cast film: This heavier film may be considered for abrasive, irregular or puncture-prone loads, provided testing shows that the additional material is necessary.
• 23 micron blown film: Blown film may suit uneven or challenging loads where puncture and tear performance are important considerations.

Thicker film cannot correct poor pallet construction. Gaps, overhanging cartons, unstable layers and sharp corners may require improved stacking, edge protection or additional restraint. The NHVR’s guidance on stretch and shrink wrapping also explains that wrapping can unitise goods, but it may not provide the complete load restraint required during road transport.

Test the Film with the Load and Wrapping Machine

Test each film on a representative pallet using the intended machine settings, including pre-stretch, tension, overlap and wrap count. Check for film breaks, punctures, crushed cartons and movement after forklift handling. Compare the cost per wrapped pallet because thinner film may not save money if it requires extra wraps, rewrapping or replacement.

Match Machine Stretch Film to Your Load With Westside Packaging Systems

Selecting machine stretch film thickness should begin with the load profile and finish with a controlled wrapping trial. Westside Packaging Systems lists cast machine films from 15 to 25 microns, with different widths, roll lengths and colours available across the range. Product availability should be checked before ordering. Matching the film to the load and equipment can improve consistency while controlling plastic use and wrapping costs.
