What Is Solvent-based Lamination and What Is It Used For?
Solvent-based lamination is a process in which two or more packaging film layers are bonded using solvent-based adhesives. In this method, the adhesive is diluted with solvents such as toluene or ethyl acetate, applied to the base layer, and—after solvent evaporation—creates exceptional adhesion between the layers.
Advantages of Solvent-based Lamination in Industrial Printing
| Advantage | Description |
|---|---|
| Very strong adhesion | Suitable for thick multi-layer packaging and heavy-duty applications |
| Heat and moisture resistance | Maintains integrity in cold storage, direct sunlight, or long-distance transport |
| Compatibility with films | BOPP, PET, metallized films, CPP, aluminum foil, and paper |
| Glossy, professional appearance | High-end finish for detailed designs and export packaging |
| Compatibility with printing | Works with flexo and gravure printing without color shift or print deterioration |
Solvent-based Lamination at Fardad Fam: The Difference Is in the Details
At Fardad Fam, solvent-based lamination is performed under precise control of temperature, speed, pressure, and ventilation. Gravure coating systems, PID-controlled thermal dryers, and experienced operators ensure a final result without bubbles, wrinkles, or bond loss. This precision preserves consistent quality at high volumes (10+ tons).
Recommended Structures for Solvent-based Lamination
| Packaging Type | Suggested Structure | Application |
|---|---|---|
| Dry foods | BOPP + CPP | Clear and durable laminate |
| Powders & coffee | Matte BOPP + PET | Matte finish with high resistance |
| Export packaging | PET + AL + PE | Barrier protection against light and moisture |
| Detergents | PET + MET + CPP | Durability in industrial environments |
Solvent-based vs. Solventless Lamination
| Feature | Solvent-based | Solventless |
|---|---|---|
| Bond strength | Very high | Medium |
| Moisture resistance | Excellent | Good |
| Drying time | Longer | Shorter |
| Odor | Requires ventilation | Odor-free |
| Applications | Industrial, export packaging | Light, economical packaging |

Your Frequently Asked Questions
What is solvent-based lamination?
Solvent-based lamination is a process in which two or more packaging film layers are bonded using solvent-based adhesives. The adhesive is diluted with solvents such as toluene or ethyl acetate, applied to the base layer, and—after solvent evaporation—creates exceptional adhesion between the layers.
What is the minimum order quantity for lamination?
The minimum lamination order usually starts from 500 kg (or about 5,000 meters) and special projects can be reviewed on a case-by-case basis.
Does solvent-based lamination alter the print design?
No. With precise control of dryer temperature and speed, the print maintains its color and quality without degradation.
Is solvent-based lamination recyclable?
Depending on the base film, yes; however, multi-layer laminates generally have lower recyclability than mono-materials.
What is the delivery time for orders at Fardad Fam?
The standard production and delivery time ranges between 7 to 12 working days, depending on the service. This includes file inspection, plate making, printing, lamination (with adhesive curing), and final slitting or pouch converting.
Is it possible to export printed products?
Yes. Fardad Fam is fully prepared to work with export-oriented brands, offering packaging, loading, palletizing, and delivery to customs or border points.
How does the order process work?
Provide our sales team with the project specs (product type, number of colors, roll or pouch dimensions, and quantity). After file review and final approval, production will begin.
