These 18 x 4 x 4 inch white corrugated mailers are manufactured from ECT-32-B single wall corrugated board and assemble into a rigid, sealed mailer without tape, glue, or staples. The one-piece fold-and-lock design closes in seconds, making it practical for high-volume fulfillment lines where consistent, tool-free packaging is a priority.
The folded structure creates a double wall panel on the front and sides, adding crush resistance that protects contents during transit. The white exterior supports clean, professional presentation suited to e-commerce brands, retail distributors, and direct-to-consumer shippers. The 18-inch interior length accommodates rolled documents, posters, banners, and similarly elongated products.
Each mailer weighs approximately 0.37 lbs, keeping per-unit shipping weight low at volume. Sold in bundles of 50 and parcel-friendly for standard carrier fulfillment.
