Sealed Air is set to introduce its new range of lightweight PP food trays and pots, which incorporate Milliken's Millad NX 8000 clarifier.

The US-based food packaging manufacturer used the Millad NX 8000 for its thermoformed Cryovac lidded trays and pots for meats, salads and other fresh produce.

The non-brittle Cryovac containers break without sharp edges and their inherent heat resistance allows them to be reheated and laminated in heat-sealing machinery without cracking or warping.

According to Milliken, the reduced packaging weight and lower carbon footprint of PP is a benefit for food processors.

PP packaging, which is ten to 30% lighter, with a 24% reduced carbon footprint compared to amorphous PET (APET), also exhibits low density.

The material can be separated from other materials in the recycling chain and will lend itself to re-use as food packaging or through energy recovery.

"According to Milliken, the reduced packaging weight and lower carbon footprint of PP is a benefit for food processors."

Milliken claims the packaging company has also benefited from processing advantages in its production chain, by using its Millad NX 8000 clarifier.

Sealed Air spokesperson Michael Thomson said the new generation Millad NX 8000 is easy to process, unlike conventional clarifying agents that do not dissolve or disperse well in PP, thereby causing a build-up on machinery during processing.

"This further plus point for the clarifier adds to its significant achievement in raising the clarity standard of our polypropylene applications for the food sector," Thomson added.

PP is said to help food producers create a new packaged foods and bring along environmental advantages of lighter packaging with a low carbon footprint during production and transportation.

Technical support has been provided by Milliken to help Sealed Air achieve clarity and offer better packaging alternatives for the food industry to support producers in meeting UK and European guidelines pertaining to minimisation in packaging weight, waste and CO2 emissions.
