Yparex first to supply bio-based adhesive tie layer

In the Netherlands, Yparex B.V. announced that they are the first supplier in the packaging industry to develop and commercialize an adhesive tie-layer for multilayer packaging films that is 95% bio-based and sourced from plants. Yparex developed a bio-based version of the company’s popular Yparex brand adhesive tie-layer resin for multilayer barrier-packaging producers. Adhesive tie layers are special polymers used in very-popular multilayer films that bond together dissimilar resins that otherwise would not adhere to each other. Such films are then used in rigid or flexible barrier-packaging structures that prevent passage of oxygen into the package.
