Selecting the correct stretch film thickness is crucial to keeping your loads secure, your packaging efficient, and your costs under control. Using film that’s too thin can lead to pallet failure — while overly thick film may increase unnecessary expenses.
In this guide, we break down how to choose the right micron level based on your load type, wrapping method, and application environment.
🎯 What Does Stretch Film Thickness Mean?
Stretch film thickness is measured in microns (µm) or gauge.
To help convert:
-
1 micron = 0.001 mm
-
80 gauge ≈ 20 microns
Most industrial stretch films range from 12 to 35 microns, depending on whether they’re used for light packaging, manual wrapping, or heavy machine-grade pallet loads.
📦 How Thickness Affects Performance
✔️ Thin film (12–17 microns)
-
Lightweight
-
Ideal for small or light loads
-
Cost-effective for high-volume, low-risk goods
-
Best for hand wrapping short-distance shipments
✔️ Medium film (18–23 microns)
-
The most versatile range
-
Suitable for mixed load types
-
Balances cost and strength
-
Used in both manual and semi-automatic machines
✔️ Thick film (24–35 microns)
-
Best for heavy-duty or irregular-shaped loads
-
Offers strong puncture resistance and load retention
-
Commonly used with fully automatic wrapping machines
-
Ideal for export, long-distance transport, or high stacking
🔍 Factors to Consider When Choosing Thickness
1. Load Weight
-
Light load (under 500 kg)? → 15–17µm is usually sufficient
-
Medium load (500–800 kg)? → Choose 20–23µm
-
Heavy load (over 800 kg)? → 25–30µm or reinforced film
2. Load Shape
-
Uniform loads = thinner film works well
-
Uneven/sharp-edged loads = thicker film prevents tears
3. Handling and Transport
-
Long shipping distance or rough handling? Use thicker film
-
Local delivery or controlled environments? You can save with thinner film
4. Wrapping Method
-
Manual wrapping: Easier with thinner, pre-stretched film
-
Machine wrapping: Choose film based on machine type and pre-stretch ratio

💡 Bonus Tip: Don’t Just Go Thicker — Go Smarter
More thickness doesn’t always mean more security. High-quality cast film or reinforced film at lower microns can sometimes outperform thicker, low-grade options.
Always ask your supplier for test data on puncture resistance and holding force — not just micron numbers.
✅ Conclusion: Match Film Thickness to Your Needs
Choosing the right stretch film thickness is about matching your load type, wrapping method, and risk factors. Using the right micron level ensures better pallet stability, lower material waste, and higher operational efficiency.
At Hanpak, we offer a wide range of stretch film thicknesses — from 12μm to 35μm, available in custom sizes and rolls to suit your exact packaging line.
