Regulatory Definition
Materials and articles that are intended to come into contact with foodstuffs must be manufactured in compliance with good manufacturing practice so that they do not transfer their constituents to food in quantities which could endanger human health. In the packaging sector, food contact materials include paperboard cartons, paper bags or specialized plastic-coated barrier boards. These substrates must be formulated from virgin fibers or approved recycled grades that undergo rigorous chemical safety testing.
This ensures that no harmful compounds contaminate the packaged food during normal distribution or extended storage. Global standards enforce these limits to secure consumer safety across borders.
Migration Prevention
Chemical substances such as mineral oil saturated hydrocarbons can migrate from secondary cardboard packaging into dry food. When designing food contact materials, manufacturers use functional barriers like aluminum foil or specialty polymer coatings to block this chemical transfer. This barrier strategy is necessary when using recycled fiber boards for cereal boxes.
This design prevents volatile chemical compounds from penetrating the inner liner.
Safety Assessment
Laboratory evaluation of packaging boards involves food simulant tests that mimic real-use scenarios. Certified laboratories place food contact materials in contact with substances like olive oil or ten percent ethanol to measure chemical release. These tests determine whether the boards comply with specific migration limits.
This scientific validation protects food quality and brand reputation.
