ม็อกอัปถุงพลาสติกสีดำสกรีนแบรนด์

A realistic studio product mockup of a single large black plastic garbage bag standing upright on a seamless white background. The bag is full and rounded with a squared base, glossy crinkled polyethylene texture, authentic wrinkles, folds, soft highlights, and a gathered tied knot at the top flaring upward. Centered front-facing composition with soft, even commercial lighting and a subtle contact shadow beneath. Printed across the front in high-contrast matte white ink are three elements: a large abstract circular logo at the upper center, the bold rounded uppercase brand name "[CENTU]" below it, and the handwritten-style slogan "[¡Programando tu futuro hoy!]" underneath. The printed artwork physically contours, distorts, and creases naturally along the rumpled plastic surface. Clean minimal aesthetic, sharp details, premium product presentation.
