The Revolutionary Film-Forming Barrier for Food and Bakery Paper

That's where REL-PAK 4700 comes in—a revolutionary silicone-based coating barrier that offers exceptional release, oil & grease resistance properties, and lengthens shelf life for bakery use while being 100% fluorine-free.

In today's fast-paced world, consumers and food industries alike are constantly seeking reliable and efficient solutions for their food and bakery needs. With growing concerns about harmful chemicals like PFAS, there is a significant desire for safe yet efficient alternatives to traditional bakery coatings. That's where REL-PAK 4700 comes in—a revolutionary silicone-based coating barrier that offers exceptional release, oil & grease resistance properties, and lengthens shelf life for bakery use while being 100% fluorine-free.

One of REL-PAK 4700’s standout features is the ability to provide superior release properties for various bakery and food industry substrates. By applying the two-part formula (REL-PAK 4700A & REL-PAK 4700B), manufacturers can ensure that their products effortlessly separate from their packaging or substrate while maintaining their integrity and quality without compromising the food products' taste, look, or feel. Additionally, REL-PAK 4700 features OCP which offers excellent slip properties for the substrate. OCP allows for easy separation between the desired packaging and the bakery products. Additionally, this coating perseveres the flexibility and foldability of your substrate, ensuring your desired packaging remains user-friendly and functional.

REL-PAK 4700 provides superior release properties to your desired substrate allowing food & baked goods to easily detach from the coated paper while  exhibiting remarkable resistance to blocking the adhesion of food or bakery products to your desired packaging, ensuring a hassle-free user experience and maintenance of the product’s visual appeal. For food or bakery products that contain oil or grease, REL-PAK 4700 also provides an excellent solution. Featuring oil and grease resistance properties prevents penetration through the substrate, allowing your packaging to maintain its durability and keeping the food product fresh. REL-PAK 4700 ensures  a dual advantage of visually appealing presentation for consumers while eliminating concerns about unpleasant aftertaste or texture. Unlike many alternatives, Impermea Material’s film-forming barrier coating dries clear and leaves no greasy residue on your substrates. 

REL-PAK 4700 is a remarkable product that excels in regulatory compliance and safety. Developed to meet and surpass the strict regulatory requirements and standards while ensuring its suitability for various applications. This coating solution adheres to requirements set forth by the U.S. Food and Drug Administration (FDA), guaranteeing the safety of materials intended for food contact and allowing manufacturers and consumers peace of mind. 

REL-PAK 4700 is a high-performing, US FDA compliant, and environmentally-friendly silicone release coating for food & bakery in-line applications. Compliance with strict regulatory standards and its status as a plastic and wax alternative with zero fluorochemicals makes it a forward-thinking choice. The non-greasy residue and transparent drying properties, along with its seamless integration into existing processes, further solidify REL-PAK 4700's position as a cutting-edge product in the field of barrier coatings.
