Using PP strapping bands may look simple—just wrap them around the box and seal, right? But in reality, small mistakes during packaging can lead to broken straps, wasted time, or even damaged goods.

Many businesses don’t realize that improper handling or poor choices in strapping can cost them money, efficiency, and customer satisfaction. So, let’s walk through the most common mistakes to avoid when working with PP straps, and how to fix them.

Mistake 1: Choosing the Wrong Strap Size

Not all packages are the same, so not all straps should be the same. Using a 5mm strap for a heavy load is asking for trouble—it will likely snap under tension.

👉 Here’s a quick guide:

• 5mm–9mm PP straps → Small, lightweight cartons (e-commerce packages, cosmetics, stationery)

• 12mm–16mm PP straps → Medium to heavy cartons (food boxes, electronics, logistics parcels)

If you don’t match the strap to the package weight, failure is almost guaranteed.

Mistake 2: Poor Quality Straps

One big issue in the market is low-grade PP strapping. These straps often have:

• Excessive curvature, which causes feeding problems in machines

• Weak thermal bonding, leading to strap detachment

• Inconsistent thickness, creating weak spots

It might feel tempting to go for cheaper options, but trust me—it costs way more in downtime and broken shipments.

Mistake 3: Incorrect Machine Settings

Even with high-quality straps, wrong machine settings can ruin everything. Common problems include:

• Tension too high → strap snaps

• Tension too low → goods aren’t secured tightly

• Seal temperature too low → strap won’t bond properly

Take a little time to adjust your semi-automatic or automatic strapping machine for the specific PP strap you’re using. It’s not rocket science, but it makes all the difference.

Mistake 4: Ignoring Storage Conditions

This mistake happens more often than you’d think. PP straps exposed to direct sunlight, high temperatures, or damp areas will lose their performance.

👉 Best storage practices:

• Keep rolls in a cool, dry warehouse

• Avoid stacking them directly on the ground

• Protect them from UV exposure

If your straps keep failing unexpectedly, sometimes it’s not the machine—it’s the storage.

Mistake 5: Not Considering Customization

Some businesses overlook the power of custom printed PP straps. Beyond packaging security, straps can also serve as branding tools. Imagine your logo and brand color printed on every shipment—it’s cost-effective marketing.

Skipping this option is not exactly a technical mistake, but it’s a missed opportunity to build recognition and trust with customers.

The Right Way Forward

Avoiding these mistakes will save you time, money, and customer complaints. The solution is simple:

1. Match strap size to load.

2. Invest in high-quality straps.

3. Adjust machines properly.

4. Store straps correctly.

5. Consider customization for branding.
