Auto-Lock Bottom vs. Snap-Lock Bottom: Assembly Speed vs. Load Capacity

Warehouse throughput speed directly dictates carton bottom structural choices.

Crash-Lock Automatic Bottoms

Pre-glued auto-bottoms pop open instantly upon manual corner compression, saving 60% packing labor time.

Snap-Lock (1-2-3 Bottom) Economy

Snap-lock bases require manual folding but incur zero pre-gluing tooling costs, ideal for short-run medium-weight products.
