In 2024, TOPCORE opened a new chapter. After years of developing dextrin adhesives for tubes, edges, and packaging applications, we faced a fresh challenge: entering the paper honeycomb market — a sector known for its technical complexity, but also for its promise as the future of sustainable packaging.
1. Why We Entered the Honeycomb Market
The initial spark came unexpectedly — during a trade fair, from a neighboring exhibitor. One conversation led to another, initial tests were conducted, and soon, regular deliveries followed. We realized that our expertise could add real value to this highly specific segment.
“At first, we had no idea what we were getting into. The honeycomb market had its own rules and requirements. But that’s what motivated us. We wanted to prove that even here, we could make a difference.”
— Petr Červinka, Co-founder of TOPCORE
2. Developing a Tailor-Made Adhesive
Adhesives for paper honeycomb require exceptional precision. Drying speed, bond strength, application method, and consistency — all differ significantly from other paper-based applications.
From a technological standpoint, we:
- Adjusted raw material ratios typically used in tube adhesives
- Tailored viscosity to match the speed and demands of honeycomb production lines
- Optimized heating and compatibility with customer machinery
Testing was done directly on the customer’s production line, covering both core bonding and lamination stages.
3. Case Study: Partnership with FORLIT
Our first major partner in this sector was FORLIT, a paper honeycomb manufacturer with over 50 years of industry experience.
Test Results:
- +7% increase in production speed
- 15–20% reduction in adhesive consumption
- Waste levels reduced to below 1%
- Annual cost savings of over €50,000
“TOPCORE’s dextrin adhesive helped the customer speed up the process, reduce raw material usage, and significantly cut the environmental footprint. The results were compelling.”
— Zdeněk Vařejka, Co-founder of TOPCORE
Additionally, the adhesive is highly biodegradable and does not clog filters during recycling — making it a perfect match for circular economy principles.

4. An Ecological Alternative Without Compromise
The BLENDECO dextrin adhesive for paper honeycombs is:
- Based on natural polysaccharides (potato dextrin)
- Biodegradable
- Highly efficient and economically beneficial
Compared to traditional PVA adhesives, BLENDECO dextrin offers clear advantages:
- Environmental Impact: PVA adhesives typically have a higher ecological footprint, whereas BLENDECO dextrin is significantly more environmentally friendly.
- Drying Speed: BLENDECO cures faster, increasing production efficiency, while PVA adhesives tend to dry more slowly.
- Toxicity: PVA may pose potential health risks. In contrast, BLENDECO dextrin is non-toxic and safer for both workers and end-users.
- Batch Cost: Although PVA adhesives may appear cheaper in the short term, BLENDECO proves to be more cost-effective over time thanks to its performance benefits and reduced material waste.
BLENDECO offers a sustainable advantage without compromising performance — delivering long-term economic benefits that clearly outweigh short-term cost considerations.
5. What’s Next?
We are actively developing:
- Borax-free adhesives tailored for honeycomb applications
- Cold-water-soluble formulations for easier on-site preparation
- New biodegradable solutions that further enhance ecological and production balance
The honeycomb market is expanding in step with growing pressure for sustainable packaging — and TOPCORE is committed to leading this transformation.
