However, there are specific conditions and standards that acrylic must meet to be considered safe for food contact. These include limitations on heat exposure and the types of foods stored in acrylic containers. Understanding these standards is crucial for ensuring food safety.
FDA Compliance of Acrylic
FDA compliance requires acrylic to be made with FDA compliant approved processes and materials that don’t leach harmful substances into food. At least 50% of the polymer units in acrylic must come from approved monomers to meet this requirement.
Acrylic materials for food contact must be free of harmful additives and meet specific FDA conditions. Such compliance allows acrylic to be safely used in food contact applications and food contact application like storage containers and food displays.
Heat Resistance and Acrylic
Heat resistance is a crucial factor in evaluating acrylic’s suitability for heat resistant food contact applications. Unlike some other plastics, acrylic has limited heat resistance and can warp or melt when exposed to high temperatures. Therefore, it should not be used in microwaves or dishwashers.
Prolonged sunlight exposure can cause acrylic to degrade, possibly resulting in chemical leaching. Therefore, it is essential to use acrylic containers in ways that avoid high heat and direct sunlight to maintain their safety and structural integrity.
Potential Risks of Using Acrylic
While acrylic is popular for food contact applications, it is not without risks. One of the primary concerns is the potential for chemical leaching, especially when storing acidic foods. Using food safe plastic containers labeled as food-safe can help mitigate this risk.
Another risk is the use of polycarbonate plastics, often confused with acrylic, which may contain BPA—a chemical associated with health concerns. Adhering to safety standards and best practices for cleaning and maintaining acrylic items minimizes these risks.
Comparing Acrylic with Other Food Grade Plastics
