Joncryl® HPB 1702: Enabling High-Performance Grease Barrier Coatings for Sustainable Paper Packaging
Joncryl HPB 1702 is an acrylic emulsion designed to help formulators balance demanding performance requirements with dynamic regulatory needs. By maintaining grease resistance after creasing and folding, delivering continued barrier performance at temperatures up to 60°C, and offering heat-sealable packaging designs, Joncryl HPB 1702 enables the development of sustainable, high-performing paper and board packaging without compromising functionality. This is an effective alternative to fluorochemical grease barriers in food packaging.
The consumer packaging market is rapidly evolving, and brand owners are working to ensure they can meet demanding packaging sustainability and performance requirements. Regulatory initiatives, including the elimination of fluorochemicals and restrictions on single use consumer packaging are increasing the demand for effective grease barrier solutions for paper and board. In parallel, convertors are tasked with improving recyclability, maintaining food contact compliance while balancing coating performance, sustainability, and convertibility.
As the demand for sustainable grease barriers for paper based packaging increases, the challenges of paper and board substrates become more evident. These paper-based substrates are naturally porous and readily absorb oils and fats. Therefore, it is essential that any coating utilized forms a defect free film that maintains packaging integrity and appearance throughout converting and packaging end use.

Grease resistance barrier properties are enabled by several Joncryl products depending on application needs, including Joncryl 74-A, Joncryl 1670, and Joncryl DFC 3030. Higher temperature performance and crease resistance is enabled by a standout resin within the BASF Printing and Packaging portfolio called Joncryl HPB 1702. It is an acrylic emulsion designed for paper and board applications that require oil and grease resistance. The ability to maintain strong grease barrier performance at temperatures up to 60°C, where oils become more aggressive, makes Joncryl HPB 1702 a valuable formulating component.
The flexibility imparted by Joncryl HPB 1702 helps minimize microcracks caused by folding and creasing. This is a key requirement for many grease barrier applications. Additionally, the ability to be heat sealed provides more options in packaging design. An added benefit of Joncryl HPB 1702 is its broad food contact compliance. As food packaging continues to evolve, Joncryl HPB 1702 is another useful tool that enables further progress towards sustainability.
