When selecting a stretch film for packaging and shipping, you may notice that thickness is measured in either microns or gauge. Both terms describe the same characteristic—the film’s thickness—but they are used in different parts of the world. Micron is the standard unit in the metric system, commonly used internationally, while gauge is the preferred measurement in the United States. Understanding how these units compare and convert can help ensure you choose the right stretch film for your specific application.
Key Takeaways
- Micron and gauge are both units of measurement used to determine the thickness of stretch film.
- Micron is the standard international unit, while gauge is more commonly used in the U.S.
- Thicker stretch films offer greater durability, but the right choice depends on your packaging needs.
- Understanding these measurements ensures you select the best stretch film for your application.
Understanding Stretch Film Thickness Measurements
Stretch film plays a crucial role in securing products for storage and transportation. However, when selecting the right stretch film, you may come across two different thickness measurements: micron and gauge. While both measure the film’s thickness, they are used in different regions and industries, which can sometimes cause confusion.
By understanding the difference between these two units, businesses can make more informed purchasing decisions to ensure optimal load containment, cost-efficiency, and durability.
What is Micron in Stretch Film?
Micron (μm) is a unit of measurement in the metric system, widely used in Europe and other international markets. One micron is equivalent to one-thousandth of a millimeter (0.001 mm). Stretch films measured in microns typically range from 12 to 30 microns, with thicker films offering better puncture resistance and holding strength.
Here’s a general guide to micron-based stretch films:
- 12-17 microns – Light-duty applications, ideal for small or lightweight packages.
- 17-23 microns – Medium-duty applications, commonly used for standard pallet wrapping.
- 23-30 microns – Heavy-duty applications, providing extra durability for securing sharp or heavy loads.
What is Gauge in Stretch Film?
Gauge is a unit of measurement primarily used in the U.S. packaging industry. The term originates from a time when film thickness was measured using different tools and methods. One gauge equals 0.254 microns, meaning that the higher the gauge number, the thicker the film.
Here’s a common gauge-to-micron conversion:
- 40 gauge = 10 microns (light-duty)
- 60 gauge = 15 microns (light-duty)
- 80 gauge = 20 microns (medium-duty, standard industry use)
- 100 gauge = 25 microns (heavy-duty)
- 120 gauge = 30 microns (extra-heavy-duty)
Micron vs. Gauge: Which One Should You Use?
The choice between micron and gauge depends on your industry, location, and specific packaging needs. If you operate in the U.S., gauge is the more commonly recognized measurement, whereas international companies and manufacturers often rely on microns.
When selecting stretch film, consider the following factors:
- Load Stability – Heavier or irregularly shaped loads require a thicker film, usually in the 23-30 micron or 100-120 gauge range.
- Cost-Efficiency – Thicker films offer better durability, but a thinner film with higher stretch capacity can be more cost-effective for lighter applications.
- Application Method – Hand stretch film is often available in lower gauge/micron thicknesses, while machine-applied films are typically thicker for enhanced performance.
Choosing the Right Stretch Film
Understanding the difference between micron and gauge ensures that you select the most effective stretch film for your packaging needs. Whether you’re wrapping pallets for shipping or securing products for storage, choosing the correct thickness helps improve load stability, minimize waste, and reduce overall costs.
