Henkel launches solventless LOCTITE Liofol LA 7845 with LA 6181, enabling retortable flexible packaging with solvent-level performance and lower impact.
Henkel introduces LOCTITE Liofol LA 7845 with LA 6181, a solventless retortable laminating adhesive designed to help flexible packaging converters move away from solvent-based lamination without sacrificing performance. The system delivers retort durability comparable to solvent-based solutions, while reducing environmental impact by eliminating solvent drying.
- LA 7845/LA 6181 is designed for high performance applications up to Retort
- This system has shown excellent performance in hot fill and other high thermal and chemical environments, such as pool chemicals.
- Adding a universal high performing solventless adhesive to your portfolio can cover many applications and significantly reduce operational complexity.
"We are extremely proud of our newest innovation in solventless technology. Enabling conversion of solvent-based technology provides significant carbon footprint and sustainability benefits and we at Henkel remain committed to leading this change within the Flexible Packaging industry"
— Andy Gold, Vice President of Flexible Packaging
Cuts greenhouse gas emissions and energy use
Eliminating solvent drying removes gas-fired ovens, cutting natural gas use, CO₂ emissions, and operating costs.
Delivers solvent-based performance in retort applications
LOCTITE Liofol LA 7845 with LA 6181 enables a shift from solvent-based adhesives while ensuring retort packaging durability.
Improves workplace safety and operator conditions
Removing solvents reduces fire risk, limits inhalation exposure, and improves working conditions on the lamination line.
For converters, solventless lamination can mean lower energy demand, faster throughput and lower operating costs because drying ovens and solvent handling are eliminated. It can also improve workplace safety and support sustainability targets through lower emissions and reduced resource use.
No drying step
Reduced energy use and operating complexity
Solventless process
Improved worker safety and reduced adhesive usage
Potential material efficiency
Optimized adhesive application and waste reduction
Retort Performance
Built for demanding, heat-sterilized applications
Eliminating solvents can create measurable environmental and cost impact. In one example scenario, this equated to ~3,200 metric tons of CO₂ per year and ~144,000 m³ of natural gas per year avoided.
