Dow Packaging & Specialty Plastics (Dow P&SP) has announced the advancement of a partnership with Ahmedabad-based barrier film manufacturer, Vishakha Group, to develop a "Recyclable Barrier Film" for Solid’s packaging. These films will be used for the first time by Dharmesh Foods, based in Ahmedabad, for vacuum-packing wheat.

Jigish Doshi, CMD of Vishakha Polyfab Pvt Ltd, said, "This recyclable barrier film solution will not only add to the shelf life of the product and reduce food waste, it also helps communities in allowing for recycling of the packaging itself."

Vipul Babu, Sales Director for Dow P&SP India SC, said, "The joint effort between Dow P&SP, Vishakha team and Dharmesh Foods saw the three companies come together to co-develop a nylon-based barrier film enabled by Dow's RETAIN Compatibilizer to make recyclable packaging for wheat. This partnership brings valuable stakeholders together to foster positive impacts with sustainable packaging solutions."

RETAIN Polymer Modifiers were developed using Dow's extensive knowledge of materials science and reactive chemistry to enable the efficient compatibilization of two otherwise immiscible materials, while maintaining critical value-added physical properties. RETAIN is specifically designed to compatibilize polyamide (nylon) and ethylene-vinyl alcohol (EVOH) into a continuous polyethylene matrix.

This innovative technology is based on a reactive, ultra-low viscosity compatibilizer. Reactive groups ‘coat’ the polar components, encapsulating them into micro-domains to enable excellent dispersion. When blended at specified ratios with pelletized barrier film recycle streams, the RETAIN polymers allow recyclers to re-process used barrier films into conventional polyethylene based recycle streams.
