The screen is a high-end design portfolio-style display board, dark background, displaying [12 / 16] paper bag layout designs of the same brand. The top is set with a design-conscious title area, including large numbers, English titles, English subtitles, and Chinese brand descriptions; the overall look should be like a brand packaging proposal page.

The main body is paper bag designs arranged in a neat grid; each bag has a unified brand identity but different layouts, including variations such as large Logo, minimalist white space, large English characters, vertical text, IP characters, product illustrations, seals, pattern elements, sidebar labels, bottom horizontal bars, mixed Chinese and English, etc.

Overall style: boutique catering brand packaging design, flat vector, modern editorial layout, strong brand sense, unified colors, clear grid, commercially viable.

Avoid tacky templates, messy layout, too many colors, text too dense, deformed bags, cheap feel, excessive cartoon, excessive 3D, real photography scenes.
