Feature |
Solvent-Based Lamination Systems |
Solvent-Free Systems |
|
Line Speed |
Provides stable operation at very high speeds (400–600 m/min). |
Suitable for medium to high speeds; viscosity control is critical. |
|
Optical Clarity |
It offers excellent transparency and a "shiny" appearance. |
Delivers very good results, but coating weight precision is crucial. |
|
Product Resistance |
Superior resistance to aggressive contents (oily, acidic, chemical) and sterilization conditions (retort). |
Ideal for general-purpose packaging with moderate barrier requirements. |
|
Drying Time |
Solvent evaporates in ovens, allowing immediate post-lamination processing. |
Typically requires 24–48 hours curing time (aging room). |
|
Energy & Cost |
Requires high oven energy to evaporate solvent. |
Much lower energy costs due to no need for heating/drying ovens. |
|
Sustainability |
Requires emission control systems. |
Environmentally friendly with low carbon footprint and zero solvent emissions. |
|
Applications |
Ketchup, mayonnaise, coffee, detergents, medical packaging, etc. |
Snacks, dry foods, biscuits, confectionery packaging, etc. |
When Should You Choose Which System?
1. When to Choose Solvent-Based Systems
- If your packaging contains highly acidic foods or aggressive chemicals
- If retort (high-temperature sterilization) processes are required
- If maximum optical clarity and perfect adhesion in aluminum foil laminations are essential
- Makro Chemical Solution: Our High Solid systems reduce solvent usage while maintaining peak performance
2. When to Choose Solvent-Free Systems
- If you want to minimize production costs (energy and waste)
- If you aim for a sustainable, “green” production line with certifications
- If you are producing fast-moving consumer goods (snacks, nuts, etc.) at scale
- Makro Chemical Solution: Our next-generation solvent-free adhesives offer very low migration risk and fast curing advantages
