Croda launches Atmer 7373 for polypropylene food packaging

Croda, UK-based polymer additives, has launched a new anti-fog concentrate Atmer7373, which is claimed to provide a unique solution to fogging in clear polypropylene food packaging.

Atmer7373 has proven to be effective in testing in both hot and cold fogging applications, and works by preventing droplet formation on plastic surfaces, keeping food fresher for long, according to

Croda polymer additives applications manager Adam Maltby said Atmer 7373 is effective in most grades of polypropylene, and has had successful results in PP homopolymer.

"As a highly loaded concentrate it is particularly useful for converters who can easily handle its pellet form. It is also useful for masterbatch producers who either cannot or do not wish to handle soft and pasty raw materials," Maltby said.

According to the company, the product is said to overcome many of the processing difficulties encountered by traditional additives at the levels needed to impart effective anti-fogging.
