Coatings and Adhesives for Direct Food Contact

Coatings and Adhesives for Direct Food Contact


Food packaging is an important aspect of everyone’s lives, and consumers today expect packaging to be safe as well as aesthetically pleasing. Food packaging must meet a variety of performance criteria, whether protecting hot or cold foods, oils and many different ingredients.

Food Packaging is Critical for Safety and Shelf Life

Food packaging must perform many important roles that food manufacturers must consider. Packaging influences consumers on the attractiveness of products as well as protecting food quality and safety. Food packaging is typically in some form of paperboard, cardboard, or coated paper with a functional layer that provides protection against moisture, grease, or chemicals. Food packaging must preserve the quality of food and improve shelf life.

FDA Fundamentals of Coatings and Adhesives for Food Contact

The Food and Drug Administration (FDA) provides food safety regulations regarding coatings and adhesives for direct and indirect food contact. The FDA does not list specific coatings or adhesives that meet the requirements for direct or indirect contact with food but rather lists the requirements for food contact applications in the Code of Federal Regulations. CFR Title 21, Section 175.300 refers to the resinous and polymeric coating requirements for food contact, and Section 175.105 refers to the regulations regarding adhesives used in food applications. There are many raw materials that may be used as components of coatings and adhesives that have direct and indirect food contact.
