Henkel Adhesive Technologies has introduced a new solvent-free adhesive system, Loctite Liofol LA 7837/LA 6265, designed for high-performance packaging applications, particularly in retort packaging for pet food.
In addition to pet food packaging, Loctite Liofol LA 7837/LA 6265 is applicable for ready meals, microwave products, and pharmaceutical packaging.

The company said, this adhesive system prioritises food safety while ensuring reliable processing and contributing to a reduction in CO2 emissions by minimising material usage and eliminating the need for energy-intensive drying processes associated with solvent-based products.
Loctite Liofol LA 7837/LA 6265 is compatible with PET/Alu/CPP packaging and modern polyolefin structures.
With a monomer content of less than 0.1% and no epoxy silane, the adhesive can withstand temperatures up to 134°C.
Its lightweight application promotes increased production efficiency, and the absence of a drying step allows for curing at room temperature, further reducing material and energy consumption.

By GlobalDataThe system is designed for safe processing at high machine speeds and under varying conditions, making it suitable for internationally standardised packaging processes.
Henkel stated that transitioning to this solvent-free system is straightforward due to its high processing stability and compatibility with existing laminating machinery.
Henkel flexible packaging market strategy manager Cagri Turkmen said: “With Loctite Liofol LA 7837/LA 6265, we are further expanding our high-performance adhesive portfolio for retort applications, offering a solvent-free solution that provides both outstanding performance and increased sustainability.
“Through this innovation, we are enabling our customers to fulfill current market requirements, reduce CO2 emissions and benefit from economic advantages due to higher production efficiency.”
In November this year, Henkel partnered with Celanese to create water-based adhesives utilising materials derived from carbon capture.
