Want Stronger Tubes? It’s Not Just About the Glue

Some customers ask:
“Why aren’t my tubes strong enough?”

But the real question is:
“Is everything in your production line working together?”

⚠️ Spoiler alert: It’s not always the glue’s fault.

3 Hidden Reasons Your Tubes or Honeycombs Aren’t Holding Up

Poor Machine Calibration

Even the best adhesive can’t fix a badly tuned machine. Uneven pressure, misaligned rollers, or incorrect mandrel speed = inconsistent bonding and wasted material.

Solution:
Regularly calibrate your line and ensure the glue application layer is consistent and optimized for your material.
Too much or too little adhesive can lead to bonding failures or unnecessary waste.

Paper That Doesn’t Match the Job

We often see customers trying to produce high-strength tubes… using lightweight or low-quality liners.
That’s like building a bridge with party straws.

Solution: Rethink your paper composition—strength comes from the whole system, not just the adhesive.

🗣️ “We see this a lot. Customers ask for stronger products, but don’t evaluate what’s under the hood.”
— Petr Červinka, Technical Director at TOPCORE

Using the Wrong Adhesive

PVA adhesives may seem convenient, but they slow you down—literally.
Longer drying times = delayed cutting, packing, or shaping.

With dextrin-based glues, especially TOPCORE liquid adhesives for paper tubes’s custom formulas, you benefit from:

• ✔️ Faster curing → earlier drying
• ✔️ Improved flat crush and bonding strength
• ✔️ Fewer clogs, cleaner production
• ✔️ Recyclable end-products

And Don’t Forget the Operator

Yes, we know—not every line is run by a PhD chemist. That’s why we deliver:

• Clear, illustrated instructions with every adhesive formula
• On-site training for your first batch
• Ongoing support for testing and optimization

Because even the best glue needs a smart team behind it.
