Empty plastic boxes are basic containers without an elastic membrane, gel, or vacuum function. They include transparent display boxes, jewelry boxes, grid storage boxes, bead boxes, and hinged clear boxes (representative series: CPK-M, CPK-E, CPK-S, CPK-L). They provide a simple, economical solution for storing, organizing, displaying, and shipping small components, samples, and finished products. Made from clear PS / PET / PP materials, they come in a wide range of sizes, with optional anti-static or black conductive versions, and support custom printing and branding.
