Barrier coatings for direct contact with food
17. October 2023

Less waste

Barrier coatings are specific types of protective films that are applied to packaging materials to enhance their properties. They are designed to reduce the penetration of moisture, oxygen, fat, flavors and other substances, thereby extending the shelf life of packaged products. This is especially important when it comes to food since it reduces the amount of waste. Typical uses include packaging for fruit, meat and animal feed.

The regulatory requirements for the disposal and recycling of production material, and, most importantly, reducing the use of plastics is a major challenge for many processing companies. In the fast food sector, packaging has a very short product life cycle, which is why it ends up in the waste disposal process very quickly. At the same time, it must meet functionality, quality and food safety requirements. ARCOLOR coatings deliver sustainable product solutions that reduce polymer content by up to 75 percent when compared to a composite substrate.

 

Kit (fat resistance) and Cobb (water absorption) tests play a key role in barrier substrates. The intended use of the barrier coating will determine how high or how low the value may be. ARCOLOR’s barrier coatings can be used to achieve kit values of up to 12 (optimum) and Cobb values of 5 (optimum). The type of substrate and the length of time it is in contact with food are decisive for achieving good values. Our new products have been ISEGA certified for direct food contact and meet the requirements of the Swiss Food Contact Materials Ordinance:

  • AR barrier varnish water DFC V1223
  • AR barrier varnish oil DFC V1226
