Document scope · ownership · intended use
Flexon Pack organizes evidence by document owner, tested sample, market and use condition. A report is shown as evidence only for the entity, site, material or product identified in that document.
A company-held SGS report is available for one biohazard specimen transport ziplock bag tested against selected US FDA 21 CFR 177.1520 requirements. Suitability for another food, temperature, resin, ink or bag construction requires a new product-to-document review.
Company-held PE-bag reports cover selected RoHS restricted substances and PPWR heavy-metal limits. These reports do not establish complete PPWR, food-contact, REACH or recyclability compliance for every product.
Requirements outside the established United States and European Union evidence scope are reviewed by destination, intended use, material formulation and finished-bag specification. No market or food-contact approval is assumed without applicable supporting evidence.
