Basic requirements for food packaging paper: All materials and products intended for food contact must undergo testing to confirm they meet food-grade safety standards. These tests encompass physical testing (primarily density, tensile strength, breaking length, elongation, etc.), chemical testing (migration tests, heavy metal content analysis, etc.), and biological testing (detection of various microorganisms, etc.). Given that food packaging paper comes into direct contact with food-and the packaged items are often intended for direct consumption-compliance with food hygiene standards is the fundamental requirement. Additionally, depending on the specific application, the paper must also meet relevant technical standards.
Paper products:
Lead (as Pb), arsenic (as As), fluorescent substances, discoloration test, coliform bacteria, and pathogenic bacteria (Shigella, Salmonella, Staphylococcus aureus, hemolytic streptococcus).
