Managing Dual Use Additives Information Flow in Plastic Packaging Declarations
Dual use additive management demands specific identity flow from resin compounders to food packers to satisfy direct food additive maximum limits.
Convertor Declaration
Meaning
Documented assurances provided by plastic processors to their customers verify that the manufactured packaging or component complies with relevant food contact and chemical safety regulations. A convertor declaration outlines the raw materials, additives, and processing aids used during production, alongside any migration limits or testing results. This document is essential for maintaining compliance throughout the packaging value chain.
Regulatory Compliance
Specific national and international regulations, such as the European Union plastic regulation or United States food contact notifications, require these formal statements to trace substances of high concern. By providing a convertor declaration, the processor confirms that the finished item does not release harmful chemicals into food or medical products above allowable limits. This confirmation relies on both formulation checks and migration testing under simulated use conditions.
Supply Chain
Downstream brand owners and distributors use these declarations to compile their own compliance dossiers for regulatory authorities. When a convertor declaration contains insufficient or incorrect data, the risk of market recall and legal liability increases significantly for the consumer-facing brand. The flow of this compliance information from resin producers through compounders to the final packer relies entirely on these structured disclosures.
Verification Testing
Migration assays and raw material audits support the claims made within these compliance documents. Standard laboratories measure both global and specific migration rates to ensure that processing conditions have not generated new volatile byproducts or degraded the additives.
