Partnership Brings Sustainable Tray Format to U.S. Market

Tray sealing specialist Proseal America of Richmond, Virginia, and Idaho-based co-packing company Hudson Blaise are partnering to bring the environmentally friendly Halopack® tray format to the North American food market.

Hudson Blaise has started production of the trays, using the Proseal SKR™ tray forming machine to enable these to be assembled on-line for a fast and efficient tray-forming, filling and sealing operation.

Halopack is reportedly the first fully hermetic cardboard tray that is suitable for both Modified Atmosphere Packing (MAP) and cool chain processing, with high barrier properties that maintain product quality and extend shelf life. It is manufactured from renewable or recycled cardboard, and the film can be easily separated from the paperboard to enable the majority of the pack to be recycled.

Available in both standard and custom sizes, the tray can be made dual-ovenable (meaning it is suitable for both microwave and conventional ovens) and is compatible with all seal formats available on Proseal’s extensive range of tray sealers, including atmospheric seal, gas flush, hermetic shrink, vacuum gas, and skin packaging. This could make Halopack ideal for a wide variety of foods, from fresh meat to snacks to ready meals.

For maximum branding and personalization, the tray can be specified with full color and double-sided printing, using a patented process that protects against ink-cardboard and close proximity contamination.

Another benefit of Halopack is that the base is constructed out of a single piece of board, whereas other similar trays on the market feature a folded construction. This folded construction has the potential for food to hang in the film through the bottom of the tray, particularly in high moisture applications.

The Proseal SKR machine can be combined with the company’s range of tray sealers, with the SKR erecting each Halopack tray at the start of the line prior to filling and sealing, for a complete in-line process.
