The oxygen barrier properties of the SURPASS HPs667-AB resin have made it possible for Tetra Pak to expand beyond ambient white milk to enriched dairy alternatives, flavored milk, toddler and baby milk in the carton bottle.
“The first generation of the Tetra Evero Aseptic package focused on ambient white milk, but the ambition was to extend to a range of liquids that could be stored at room temperature throughout the supply chain and in retail outlets,” said Tunc Turkmen, product director Tetra Evero Aseptic at Tetra Pak.
“To develop this, Tetra Pak searched for a new polyethylene with the exceptional oxygen barrier properties that the Tetra Evero Aseptic package required. Using NOVA Chemicals’ HPs667-AB resin, we are able to expand into some of the best performing categories in the global dairy market, such as flavored and vitamin fortified milk,” he said.
Resin can be used in other packaged goods
NOVA Chemicals worked with Tetra Pak on retaining the barrier properties throughout the production process and the use of pigmented resins.
NOVA Chemicals says that the HPs667-AB resin offers barrier and stiffness performance, which helps converters and brand owners improve the sustainability of packaged goods in applications including cereal, crackers, dairy and other liquids.
NOVA Chemicals, which develops and manufactures chemicals and plastic resins, is headquartered in Calgary, Canada, and is a wholly owned subsidiary of the UAE-based International Petroleum Investment Company (IPIC).
