For over 30 years, Winpak has been one of North America's leading manufacturers of thermoformed plastic packaging materials. During this time, we have developed a sophisticated co-extrusion process which bonds together layers of high performance plastic resins to create a superior, rigid high-barrier material that safeguards foods and other products from oxygen, moisture, and ultra-violet light. The end result is a package that not only extends product shelf life by keeping the product fresher, longer, but also has broad consumer appeal.

Winpak expands upon this expertise in barrier plastic packaging by offering custom barrier packaging designed to meet the demanding requirements of the retort process. Made by combining several technically advanced materials in a multi-layer plastic structure, Winpak retort containers can be used in many retort applications. With outstanding barrier and retort performance properties, Winpak retort containers are also microwavable. Winpak recently introduced Revoh™, a breakthrough barrier retort technology which extends shelf life and reduces packaging costs.

Retort plastic containers can be designed for a broad array of specific retort applications. Custom possibilities include unique shapes, colors, logos, and decorations which will bring instant product recognition and promote the product's identity. Functionally, Winpak retort plastic containers provide excellent packaging performance and will stand up to the harsh retort environment. Winpak can also supply lidding specifically designed for retort applications.
