Sustainability goals are shaping adhesive choices too. Bio-based hot melts are formulations in which part of the fossil-based components is replaced with renewable materials.
What does bio-based mean?
It means a given percentage of the product's carbon content comes from plant or other renewable sources. The share varies by product and can be documented by independent tests.
Performance
Today's bio-based hot melts offer performance close to conventional products in packaging and assembly. Still, every application should be trialled.
| Criterion | Assessment |
|---|---|
| Application temperature | Usually similar to standard products |
| Setting speed | Depends on formulation; trial it |
| Heat resistance | Check for the application |
| Odour and colour | May differ for some products |
Why choose them?
- Carbon footprint reduction targets
- Brand owners' demand for sustainable packaging
- Expectations of compatibility with recycling processes
Tips for switching
- Run a production trial on existing equipment.
- Clarify in advance which certificate or declaration your customer requires.
- Re-optimise coat weight; a different viscosity can mean different consumption.
