COF Tester For Plastic Film | Solve Sticky & Slippery Film Issues on Packaging Lines

On the packaging line, film is either “too sticky”—jamming the machine and triggering frequent alarms—or “too slippery”—causing sealing slippage and unstable stacking. Quality control staff end up running back and forth with different batches of film, but without a unified standard to rely on.

That standard is the coefficient of friction (COF). Think of it as the film’s “personality indicator”—it tells you whether this roll is clingy or smooth.

At ShouNuo Instrument, a factory-direct manufacturer with over ten years of deep expertise in flexible packaging testing, we have developed our own plastic film COF testers to measure that personality clearly. No middlemen—technical questions go straight to our in-house engineers. Reliable and hassle-free.

1. Two Main Models – Which One Fits Your Needs?

We offer two core models for plastic films: SN‑MC1E and SN‑MC2E. Here’s a quick comparison of specs and special features:

Comparison Item	SN‑MC1E (Basic All‑rounder)	SN‑MC2E (Advanced Analytical)
Instrument Image
Force Range	0~10N (customizable)	0~2N (better for thin, slippery films)
Accuracy Class	0.5 grade	0.2 grade (higher)
Measurement Error	±2%	±1% (more precise)
Test Speed	100 mm/min (150 mm/min optional)	0~200 mm/min, stepless variable
Screen Operation	7‑inch touchscreen + smart system
Core Functions	① Demagnetized table + slider (anti‑interference); ② Point‑capture for any instant data; ③ Stores 20 sets + one‑click print; ④ Password‑protected calibration; ⑤ Measures both static and kinetic COF in one run
Same plus	/	① Built‑in real‑time curves (watch changes during test); ② PC connection for A4 reports (cable included)
Standard Configuration	Main unit + mini printer + power cord + slider	Main unit + mini printer + power cord + slider + data cable
Dimensions	470×340×260mm	500×340×250mm

Both models support customization (range, slider mass, sample thickness, etc.). As the original manufacturer, we simply adjust to your requirements.

2. What Do These Features Actually Do? In Plain Words

• 7‑inch touchscreen + smart system – No more old button panels. Just tap like on a smartphone—intuitive even without a manual.
• Demagnetized treatment – Both the table and slider are demagnetized and checked for residual magnetism, eliminating interference for rock‑stable data.
• Point‑capture – Want the friction force at the exact “start‑up” moment? Press once to lock that instant value—especially useful for films with sticky coatings.
• Store 20 sets + one‑click print – Print results immediately and attach to sample bags for seamless communication between shop floor and QC.
• Password‑protected calibration – Calibration parameters are locked with a password. Only authorized personnel can adjust—no worry about new operators messing up.
• Static & kinetic in one test – Previously needed two separate runs; now one test does both, doubling efficiency for batch inspections.

3. Is the MC2E’s Extra Functionality Worth It?

The SN‑MC2E goes further. If you’re doing routine incoming inspection, the MC1E is more than enough. But if you’re:

• Developing new materials and want to observe friction trends.
• Required to present A4 reports with curves to your clients.
• Or need to export data to a PC for deeper analysis.

Then the MC2E is made for you. Its real‑time curve shows whether the COF is steady or fluctuating—great for diagnosing material uniformity. The PC software outputs professional A4 reports that impress larger customers and add credibility to your data.

4. Selection Guide

• For daily incoming inspection, shop‑floor spot checks, or tighter budgets → Choose SN‑MC1E – rugged, fast, and easy to operate.
• For R&D labs, QC centers, high‑precision requirements, or formal reporting → Choose SN‑MC2E – a small extra investment for deeper insights and professional presentation.

Whichever you pick, our plastic film COF tester gives you firm control over the slip properties of incoming materials and finished products.

5. Why Choose Us – The Factory Direct Source?

We have our own factory in Zengcheng, Guangzhou—no OEM, no trading company. After‑sales support connects you directly with our engineers, not a call center. Customization is flexible: range, speed, slider weight—just tell us, and we’ll adjust. Prices are competitive with no middle‑margin markup. We hold EU CE certification and ISO 9001 quality management, and our products are exported to many countries. Quality you can trust.

As a professional factory‑direct COF tester manufacturer, we know the value of every data point on your production line—measure it right once, and save half a day of downtime.
