Modelled after an envelope’s opening and closing mechanism, these bags are precision-cut and bonded from pure kraft paper, featuring a flat opening and smooth operation. They come with a built-in folded-edge seal for simple and quick sealing. Lightweight, flexible, and durable, they resist compression and folding while offering attractive printing results, along with basic dust-proof and moisture-proof properties. Compact and portable, they require no complex sealing tools and are ideal for shipping samples, storing accessories, enclosing documents, and packaging small cultural and creative goods—making them extremely practical.
