Lotnicza 1, 82-500 Kwidzyn\") and centrumpapieru.pl (Kod EAN, A4, 80 g/m², 500 sheets, CIE 161, PLN 30.00). The 2006 capture described the same barcode as copier/inkjet/laser/fax paper, cited only for identity. Category GPC 10001304 Paper/Card - Unprinted; no ingredients or nutrition, non-food.\n* **Specifications** come from the maker's own product card (POL_Lux_karta_produktowa_pefc.pdf, MM Kwidzyn, Feb 2024): 80 ± 2 g/m², caliper 108 ± 3 µm, CIE whiteness 161 ± 3, brightness D65 109 %, opacity 94 %, moisture 3.5-5.0 %, Bendtsen roughness 180, bending stiffness MD 124 / CD 56 mN, ECF-bleached woodfree furnish, PN-EN ISO 9706 permanence. Each row carries its observation (card-2024 for the grade, ream-2026 for the pack).\n* **Relations.** brand_owner_at_sale and manufactured_by → company/mm-kwidzyn (sourced: the POL brand site is published by MM Kwidzyn, the retailer prints the manufacturer block, and Open Food Facts records the same brand_owner). gs1_prefix_owner is `derived` only: prefix 5901657, owner per the OFF brand_owner plus the POLspeed ream 5901657012369 in the same block. No company stub stated the prefix and no public register names the licensee, so the company stub carries it as `gs1_prefixes_inferred`, not `gs1_prefixes`, and the length is flagged as a research gap.\n* **Stubs.** brand/pol (the masterbrand whose logo signs the range; POLlux kept as a `name` alias on the product and as the family), family/pollux with its A4/A3 and punched variants, company/mm-kwidzyn with KRS 0000292525 / NIP 5810004587 from the Ministry of Justice KRS API (sole shareholder MM Board & Paper GmbH, 1,800,000 shares, PLN 90 m capital, extract as of 16 June 2026) and parent_org Mayr-Melnhof Karton from the 11 August 2021 completion of the Kwidzyn purchase. Those two group companies are referenced but not created here.\n* **Not claimed.** No pack photograph exists (OFF holds none; the maker's packshots carry no stated licence), so no image was posted. Carton/pallet configuration and the EU Ecolabel/PEFC licence numbers are unresolved and recorded as gaps. The certificate claims (ColorLok, PEFC, EU Ecolabel) are noted as sitting in a block that covers the POL range, not a per-grade statement."},"product":{"schemaVersion":2,"identity":{"gtin":"05901657012413","name":"POLlux A4 80 g/m² 500 arkuszy","brand":"brand/pol","colour":"white","family":"family/pollux","status":"active","name.en":"POLlux A4 80 g/m² 500 sheets","summary":"Uncoated woodfree office paper from the MM Kwidzyn mill in Poland, sold as a 500-sheet A4 ream of the POL range.","category":"category/10001304","pack_format":"ryza (ream)","piece_count":500,"country_of_sale":["PL"],"country_of_origin":["PL"],"default_observation":"ream-2026"},"selectedId":"ream-2026","observations":[{"id":"card-2024","label":"MM Kwidzyn product card, POLlux A4/A3 80 g/m2","kind":"label","market":["PL"],"language":"pl","validFrom":null,"validUntil":null,"observed":"2024-02","status":"supported","source":"^kartapol","note":"Technical specification published by the maker for the POLlux grade in A4 and A3;
