CANVERA™ Polyolefin Dispersions offers an excellent food and flavor protection profile, excellent adhesion, corrosion protection and flexibility without impact on flavor. This innovation eliminates material traditionally found in epoxy or alternative coating systems that are of concern for many consumers.

CANVERA™ Polyolefin Dispersions are a new and innovative technology for formulators to develop new coatings systems to replace incumbent epoxy coatings

A can-do approach to packaging
We love the convenience of cans – great for grabbing drinks on the go, fantastic for preserving flavours of foods. And now there’s a progressive approach to can coatings that means consumers can still enjoy the benefits without the health concerns.

CANVERA™ Polyolefin Dispersions from Dow offer a water-borne, spray-applied replacement for epoxy coating systems, minimizing epoxy and bisphenol A (BPA) and delivering brand owners a next generation approach to safe, sustainable can coatings that will appeal to health-conscious consumers.

Inspirational technology inspires design advances
The secret behind CANVERA™ Polyolefin Dispersions? Patented BLUEWAVE™ Technology from Dow, facilitating creation of ultra-thin, thermoplastic film coatings that can be spray-applied from water-borne formulations to the inside of cans, protecting contents from changes in colour, taste or appearance.

The wafer-thin, protective lining can be applied directly to metal surfaces by the same equipment used for current epoxy coatings, and offers the features brand owners rely on: excellent food and flavour retention, adhesion, and corrosion protection.

CANVERA™ Polyolefin Dispersions : a drop-in, next generation option, helping progressive brand owners to move away from materials of concern without compromising on can performance.
