The choice of material depends on your brand positioning and protection needs. PE (Polyethylene) is the most common for its softness and cost-effectiveness, while CPE (Chlorinated Polyethylene) offers a premium frosted texture that is anti-static and prevents socks from sticking to the bag. For eco-conscious brands, PLA+PBAT biodegradable materials are increasingly popular to meet global plastic reduction trends. If visibility is a priority, BOPP (Biaxially Oriented Polypropylene) provides high transparency and stiffness, making it ideal for retail display.
