Producing food packaging involves lots of rigorous safety tests. It's best to work with a partner whose microspheres meet regulations approved by authorities worldwide. Expancel FG products have been given the green light by the FDA (US Food and Drug Administration) for use in agglomerated wine corks. It meets European regulation 10/2011 for plastic packaging and has been approved by the Germany's BfR food safety authority, for use in paper packaging. For any application that packages food and beverages, Expancel FG will enhance its safety and consistency. It's a popular ingredient in the production of agglomerated and synthetic wine corks, cap seals, coatings and packaging.
