Selecting the appropriate material is critical for both protection and brand image. LDPE (Low-Density Polyethylene) is the most common choice due to its high clarity, soft touch, and excellent flexibility, making it ideal for high-end apparel. PP (Polypropylene) offers superior transparency and stiffness, often used for shirts to provide a 'crisp' look. For eco-conscious brands, prioritize GRS-certified (Global Recycled Standard) recycled plastics or compostable materials like PLA+PBAT, which help meet international sustainability regulations.
