High-Performance Solutions for Flexible Packaging 

Flexible packaging converters are under increasing pressure to improve line efficiency, maintain laminate quality, and meet regulatory requirements without sacrificing productivity or consistency. Bostik’s portfolio of laminating adhesives for flexible packaging addresses these challenges through two complementary product families: PURELAM™ solventless systems and PURETHANE™ water-based systems. 

Together, these technologies provide a flexible toolkit for processors running a wide range of packaging structures, substrates, and application conditions.

PURETHANE™ Water-Based Laminating Adhesives 

PURETHANE™ adhesives are based on polyurethane dispersion (PUD) chemistry, offering an alternative to traditional water-based acrylic systems with improved processing and aesthetic performance. 

Key performance advantages of these adhesives include the following: 

• Higher line speeds due to cleaner running and excellent foam control 
• Improved laminate clarity and appearance 
• Fewer issues, such as cell plugging and poor leveling 

PURETHANE™ Systems and Grades 

PURETHANE™ adhesives may be used as single-component systems for low-demand applications or as two-component systems when paired with a cross-linker to enhance performance.

PURELAM™ Solventless Laminating Adhesives 

PURELAM™ products are two-component solventless polyurethane systems, designed for high-efficiency lamination without the need for drying ovens or solvent handling. 

These systems are particularly well suited for the following: 

• Flexible food packaging 
• High-speed lamination lines 
• Applications requiring low migration performance
