barrier with release properties designed for food & bakery paper applications

REL-PAK 4700

REL-PAK 4700 is a water-based, low MVTR, coating engineered to deliver exceptional release performance for food and bakery packaging. This PFAS-free, recyclable, and repulpable coating provides a sustainable solution without compromising functionality.

Formulated for use on bakery substrates, REL-PAK 4700 offers clean, consistent release for sticky or delicate baked goods. It is heat sealable, printable with water-based inks, and compatible with both cold-set and hot-melt adhesives, making it ideal for converters seeking a drop-in alternative to traditional silicone or polycoated liners.
