The trend toward individualized taste has resulted in wide-ranging diversification, seen for instance in the increasing supply of craft beer. As new product variants are usually produced in existing plants, seals are coming into contact with considerably more flavors. Freudenberg Sealing Technologies has developed the Fluoroprene XP material family to meet this challenge. It is structured so that flavors cannot be transferred.
Many consumers are also interested in healthy beverages produced with as few preservatives as possible – yet still have a long shelf life. More and more aggressive detergents are needed to prevent bacteria from getting into the beverage. Seals must be resistant to these acids and alkalis.
For beverages with a solid component such as smoothies, no product residue should remain on the seals, such as seeds in a strawberry smoothie. Seals should also be stiffer and harder to tear as smoothies apply more pressure than completely liquid beverages.
