9x12 poly mailer measures approximately 9" x 12" (about 22.9 cm x 30.5 cm) when laid flat, not counting the flap. Interior capacity is slightly smaller due to side seams. Made from polyethylene (PE), each bag features excellent water and tear resistance along with a strong self-sealing adhesive strip for quick, secure closure.
The 9x12 size works well for small, lightweight, non-fragile items like a folded t-shirt, a thin long-sleeve, leggings, a light kids' outfit, small soft accessories, or a couple of thin garments packed flat. It's also a great fit for documents, handmade goods, and boutique packaging — a versatile everyday size for small e-commerce sellers.

Their lightweight construction with strong stickiness helps reduce transportation costs while ensuring product safety in transit.
