Surface Energy Measurement Methods for Polyolefin Packaging Films
Polyolefin surface energy audits require OWRK polar component tracking and dyne fluid validation to prevent lamination delamination and slip agent masking.
Food Contact EU 10 2011
Compliance Standard
Regulatory frameworks establish specific purity and migration limits for plastic materials and synthetic components intended for direct food contact. Compliance with food contact eu 10 2011 governs plastic layers, functional coatings, and synthetic linings laminated to paperboard packaging in European markets. The regulation defines an Union List of authorized monomers, additives, and starting substances alongside overall migration limits of ten milligrams per square decimetre of food contact surface.
Provisions stop applying to pure paper and paperboard substrates that lack plastic layers or synthetic resin coatings.
Migration Testing
Chemical migration assessments verify that packaging components do not transfer harmful substances into food products. Under food contact eu 10 2011, testing protocols employ food simulants like ethanol solutions and vegetable oils to simulate real-world storage conditions. Standardized exposure temperatures and contact times evaluate both overall migration and specific migration limits for regulated substances such as heavy metals or plasticizers.
Multi-layer packaging structures containing paperboard and plastic film must prevent substance migration under defined temperature profiles. Declaration of compliance documents must accompany materials throughout the supply chain, detailing testing conditions and verifying that chemical migration remains below legal safety thresholds for intended food contact applications.
Functional Barrier
Multi-layer laminates incorporate functional barriers to prevent unlisted substance transfer from recycled paperboard cores into food matrices. Applying requirements from food contact eu 10 2011 validates whether internal polymer coatings block chemical migration from outer packaging layers. Structural barrier integrity prevents food contamination during extended shelf storage.
