Yucai’s Corrugated Mailer Box wholesale – Perfect for Bulk Packaging
At Yucai, we have redefined the flexible wholesale of corrugated boxes. Designed specifically for bulk packaging needs, our boxes combine superior durability with cost-effective pricing and do not require a minimum order quantity (MOQ).
What Is Mailer Box
A mailbox is a corrugated cardboard transport box design that safely and effectively delivers goods through postal or express delivery services. Usually pre-folded, with self-sealing functions (or easy to close with tape), it is lightweight yet sturdy, providing excellent protection during transportation against bumps, scratches and minor impacts. Unlike traditional transport boxes, mailboxes are usually thin and compact, and their size, printing and brand can all be customized. This makes them an ideal choice for e-commerce enterprises to transport small and medium-sized products such as clothing, cosmetics and electronic accessories.

What can Yucai do for your Corrugated Mailer Boxes
-
Choose material thickness as your need
For the needs of corrugated mailer boxes of different sizes, we offer precisely matched corrugated material options. Among them, E-flute and F-flute are the preferred materials for small and medium-sized corrugated boxes – the common thickness of E-flute is 1.5-2mm, and it has good rigidity and buffering performance. The common thickness of F-flute is 1 to 1.2mm. The material is thinner and lighter, but it can ensure basic protection and is suitable for the packaging of medium and small-sized products that have requirements for lightweight packaging.
If your corrugated box is large in size and requires strong load-bearing and protective capabilities, We will choose B flute material. Type B flute have an excellent thickness, which can form a stable packaging structure, effectively resisting compression and impact during transportation and handling, and building a solid safety protection barrier for large-sized products
