Saco plástico preto com logotipo personalizado

Create a photorealistic studio product shot of a single glossy black plastic trash bag or merchandise bag standing upright, full and slightly bulging, centered on a clean white background with soft even lighting and a subtle floor shadow. The bag is tied tightly at the top, with gathered wrinkled plastic forming a knot and a ruffled neck, and the body shows realistic crinkles, folds, shiny highlights, and stretched black polyethylene texture. On the front center, print a crisp white custom business logo in a carnival-style badge: a large outlined banner and geometric emblem with small stars, featuring the main brand text {argument name="brand name" default="ARCADIAS"} in bold playful lettering, a large arch shape incorporated into the wordmark, and the tagline {argument name="tagline text" default="LA ESQUINA DIVERTIDA"} curved underneath. Keep the logo flat white ink as if screen-printed directly onto the bag, high contrast, perfectly centered, with no other objects, no hands, no clutter, and no background decoration.
