Tips on Checking PVC Coated Webbing Quality

If you need PVC coated webbing for pet collars, dog leashes, backpack straps or horse bribles, quality always matters.

Here are 5 tips to guide you through the coated material quality inspection.

1. Check Material Quality
Look for:
- Smooth PVC Layer: Make sure the PVC layer covers the webbing evenly, with no cracks or thin areas.
- Strong Base Fabric: The fabric under the PVC (like polyester) should feel tight. Loose threads mean poor quality.

How to Test:
- Bend the webbing sharply. Bad PVC will crack or peel off.
- Rub it hard with a dry cloth. If color rubs off easily, the coating is weak.

2. Test Strength
Look for:
- Weight Capacity: The webbing must hold the weight it claims (e.g., 1,000 lbs for dog leashes).
- Stretch Amount: Good webbing stretches very little when pulled (≤15% stretch at half its max load).

How to Test:
- Use a strength testing machine if available, or check test reports from labs like SGS.
- For a quick test, hang weights on one end and see how much it stretches.

3. Check Scratch Resistance
Look for:
- Durable Surface: The PVC shouldn't scratch easily after rubbing.

How to Test:
- Rub the webbing 50 times on concrete or rough fabric. Good quality shows little wear.
- Check if the color fades after rubbing-this means poor sun resistance.

4. Test Coating Bonding
Look for:
- PVC Sticks to Fabric: The PVC layer should not peel off the fabric when you are pull it hard.

How to Test:
- Try peeling the PVC by hand. If it comes off easily, the bonding is bad.
- Soak the webbing in water for 24 hours. If layers separate, quality is poor.

5. Check Safety & Temperature Limits
Look for:
- Safe Materials: Confirm it meets RoHS/REACH standards (no harmful chemicals).
- Works in Heat/Cold condition: Should stay flexible in cold (-20°C) and not melt in heat (70°C).

How to Test:
- Ask suppliers for related documents such as ROHS/REACH certificates.
- Put samples in a freezer or oven, then check flexibility and stickiness.

Helpful Tips:
- Always ask for samples before big orders.
- Check the manufacturing history and experience of the factory.
- For dog products, choose odor-free, non-toxic coatings.

By following these steps, you can avoid low-quality webbing and ensure your products last longer.
