Photograph of a 25 kg bag of Codex EX 80 Flow cementitious screed. The bag has bright yellow-green packaging with a large black 'codex' logo at the top and prominent white 'EX 80' and small 'FLOW' lettering. A bold black headline reads 'ZEMENT-FLIESSESTRICH' with a German product summary below stating it is a fast‑hardening cement flow screed for bonded screeds, separation layers or insulation layers. On the lower left the weight '25 KG' and article number 'Art. No. 89079' are visible. A QR code with the label 'SCAN TO PLAY', CE marking and an EC1 emissions sticker appear on the front. The packaging shows creases and paper texture; a green vertical stripe runs along the left edge and a green triangular area on the lower right displays the UZIN|LUTZ logo and the slogan 'YOUR FLOOR. OUR PASSION.' The image focuses on the front of the bag and clearly displays branding, product name and technical markings.
