Assemble in seconds. Protect in style.
Pre-glued auto-lock folding cartons that assemble in seconds to reduce fulfillment labor costs.
Auto-Bottom Boxes, also known as auto-lock bottom or crash-lock cartons, are the industry standard for high-volume packaging lines that require rapid fulfillment. The pre-glued bottom flaps automatically fold out and lock into place when the flat-folded carton is squeezed open, completely eliminating the need for tape, glue, or complex folding steps during assembly. This mechanical design makes them highly efficient for manual packing lines and automated fulfillment centers alike.
Cubit manufactures these cartons from premium-grade paperboard and corrugated micro-flute to match your specific product weight and protection requirements. The top closure features a classic tuck flap with optional friction locks or dust flaps to keep your items secure during transit. The flat-bottom structure also provides excellent shelf stability, allowing your products to stand upright in retail displays without tilting.
When you work with Cubit, you get access to precise structural engineering and high-resolution custom printing on both the interior and exterior of your cartons. Our direct-to-plate printing capabilities ensure sharp text, accurate brand colors, and clean creases for a premium presentation. Whether you pack cosmetics, pharmaceutical bottles, gourmet food items, or retail electronics, these boxes offer the perfect balance of structural integrity and operational efficiency.
