PPG Industries has introduced two new coatings for food cans in the US, which comply with the food-contact regulatory requirements.
The Nutrishield and Nutrishield Solista coatings use Nutrishield Solista technology, which has been designed as a Bisphenol A non-intent (BPA-NI) coating with enhanced flavour-neutral properties, ensuring that even easily affected products can pass extensive flavour tests.
Developed as an internal protective spray coating, Nutrishield Solista is intended for drawn and wall-ironed cans, which are used for ready meals, soups and infant foods, including milk.
Claimed to be the first of its kind for the food-can industry, the BPA-NI coating is suitable for low-pH to high-pH and fatty foods.
It also offers the advantages of sulphur-resistance and meat-release properties, which makes them suitable for soups, meat-based meals, various vegetables, tomato-based sauces and foods, and pet foods.
The new launches have been certified by independent institutes to be in compliance with the North American and European standards and are food-contact compliant, says PPG.
PPG packaging coatings global technical director Charles Turner said: "The patented Nutrishield Solista internal spray coatings technology resulted from intensive research and development that involved extensive testing, pack-testing and industrial scale-up trials.
"They are suitable for all two-piece drawn and wall-ironed can sizes, and they can be introduced to food-can-makers’ lines that use standard equipment without major modifications.
"Additionally, Nutrishield Solista coatings cover all weight specifications and exhibit excellent cure robustness."
The firm has already used the Nutrishield Solista spray coatings, which had been launched in Egypt last year, in more than three billion food cans by the end of this year.
The US launch of the products is a part of the company strategy to enable its global production and supply.
