Studyjny mockup czarnego worka na śmieci z logo

Realistic commercial studio product photograph of a single large black plastic garbage bag standing upright, fully stuffed into a rounded bulging shape with the top gathered tightly and tied in a small knot. The bag is made of glossy, crinkled polyethylene with crisp specular highlights, realistic creases, tension folds, and subtle surface translucency. Centered on the front is a crisp white corporate logo: a stylized icon composed of vertical lightning-bolt bars rising diagonally above a geometric mark, with the bold uppercase word "[CODETEL]" printed underneath. The logo appears screen-printed directly onto the plastic, conforming naturally to the wrinkles while remaining sharp and legible. Minimalist seamless white studio background, soft diffused lighting from the upper front-left, subtle ground shadow, centered square composition, no people, no extra props or text.
