Pearl cotton bags, also known as EPE (Expandable Polyethylene) foam bags, are lightweight, flexible, and shock-absorbent packaging solutions. Made from closed-cell foam, these bags provide excellent cushioning for fragile items such as electronics, glassware, medical devices, and automotive parts. The material is non-abrasive, moisture-resistant, and recyclable, making it a preferred choice for both industrial and consumer packaging. Unlike bubble wrap, pearl cotton bags offer a softer, more uniform texture and can be manufactured in various thicknesses, colors, and sizes. They are widely used in e-commerce, logistics, and manufacturing sectors for protective packaging.
