Corrugated auto lock bottom boxes are crafted from multi-layer corrugated board for small, delicate products, e-commerce shipping, and retail display. Designed as an integrated die-cut one-piece structure with an auto-lock base, this box assembles easily by folding alone, with no glue, tape, or staples required. Its corrugated build also delivers reliable cushioning and structural strength for transit and stacked storage.
Yucai’s corrugated auto bottom box adopts integrated die-cut one-piece molding with preset creases and an auto-lock structure. It can be folded and locked in place manually in seconds, without the need for glue, tape, or any auxiliary tools. The assembly requires no professional skills, enabling quick operation for all staff. Compared with traditional glued or ordinary insert boxes, it greatly simplifies the packaging process, effectively saves manual assembly time and improves overall packing efficiency for mass order production.
Combined with a multi-layer corrugated board structure, the auto-lock bottom forms a stable, closed-loop force-bearing structure after folding and locking. The bottom connection is tight and firm, making it difficult to loosen or collapse under stacked pressure. Different from ordinary soft card boxes, Yucai’s corrugated auto bottom box features excellent stiffness and overall toughness. It can bear long-term stacking and heavy-pressure transportation, maintain a stable box shape, and effectively avoid softening, sagging and deformation, with far better durability than conventional packaging boxes.
The integrated auto bottom structure makes the whole box more integrated and structurally stable. The high-toughness corrugated layer can effectively buffer external impact, vibration, and squeeze during express delivery and long-distance transportation. We provide comprehensive anti-collision, anti-pressure and anti-scratch protection for 3C accessories, cosmetics, hardware, food, fine goods, etc., significantly reducing the damage rate of products during logistics and warehousing.

We support B, E and F, three common corrugated flutes paired with sturdy kraft liner for your auto lock bottom boxes, and you can pick the right thickness according to your product weight. Thin F-flute works for lightweight small cosmetics, jewelry and handicrafts to avoid excessive box volume; medium E-flute balances hardness and cost for daily snacks and accessories; thick B-flute brings strong load-bearing capacity for heavier hardware and electronic parts.
The smooth box surface supports full-color printing, hot stamping and embossing. Your logos, patterns and product info can be fully displayed without dead angles. Exquisite craft upgrades packaging texture, standing out on retail shelves and leaving deep professional impressions on buyers to strengthen your brand competitiveness.
