Description
These flat corrugated cardboard boxes are ready-to-assemble shipping containers measuring 12 inches long by 9 inches wide by 2 inches high, ideal for consolidating small to medium-sized items for domestic and international shipment. Sold in convenient 25-box packages, they feature kraft paper construction with 200lb. test strength and ECT-32 rating, making them a cost-effective standard solution for warehouses, e-commerce fulfillment centers, and logistics operations.
Each box in this package delivers 200lb. burst strength and ECT-32 edge crush test performance, which indicates the box can withstand 32 pounds per inch of edge crush resistance—a critical metric for stacking and transit durability. The kraft corrugated construction provides lightweight yet rigid protection for fragile items, electronics, apparel, and small parts. At 12″L x 9″W x 2″H, these boxes offer an optimal footprint for standard pallet configurations and UPS/FedEx dimensional weight calculations. The flat blank format means boxes arrive unassembled, requiring minimal storage space before deployment, while assembly takes seconds with basic box taping. Natural kraft paper finish is FDA-approved for direct food contact (when applicable), and the corrugated fluting provides inherent cushioning without additional void fill in many applications.
Small-to-medium product shippers, subscription box services, and fulfillment centers rely on this box size for clothing, books, cosmetics, jewelry, and consumer electronics. E-commerce merchants use them extensively for polybag-wrapped merchandise and lightweight inventory. Manufacturing facilities deploy them for component distribution and inter-warehouse transfers. Postal and parcel services leverage the 12x9x2 dimensions for regional sorting and final-mile delivery optimization. Specialty retailers in food, pharmaceuticals, and industrial supply favor this format for sample shipments and bulk order consolidation. The compact profile also suits gift packaging, promotional box sets, and branded unboxing experiences where presentation matters alongside protection.
When sourcing corrugated shipping boxes, prioritize ECT and burst strength ratings relative to your product weight and handling environment—200lb. test suits most light-to-medium payloads up to 15-20 lbs. per box depending on package density. Verify interior versus exterior dimensions to account for flap overlap and ensure products fit without excessive compression. Consider whether single-wall versus double-wall construction meets your needs; these are single-wall, adequate for most applications, but heavier items may require double-wall upgrade. Evaluate kraft versus white-lined kraft finishes based on brand presentation and moisture exposure. Check bulk pricing tiers across different package quantities (25, 50, 100+) to identify cost-per-unit economies. Finally, confirm that boxes meet carrier specifications for your primary shipping provider to avoid surcharges or rejection at intake facilities.
What size items fit in a 12″ x 9″ x 2″ corrugated box?
This box dimensions accommodate items up to approximately 11.5″ x 8.5″ x 1.5″ internal space (accounting for board thickness). Ideal products include folded clothing, paperback books, small electronics, cosmetic sets, office supplies, vinyl records, artisanal food products, and bundled components. For exact fit confirmation, subtract 0.5 inches total from each external dimension as a conservative estimate, then cross-reference with your product specifications.
How do I calculate the correct box size and strength rating for my shipment?
First, measure your product’s dimensions when packaged or wrapped—add 1-2 inches for void fill and movement protection. Next, determine total payload weight including all contents, protective materials, and the box itself (typically 0.8-1.2 lbs. for this style). Cross-reference payload against the box’s burst strength or ECT rating: 200lb. burst handles approximately 15-20 lbs. safely with standard stacking. Account for multi-box pallets and drop-test scenarios—higher stacks require stronger boxes lower on the pallet. Finally, verify compliance with your carrier’s maximum weight limits and dimensional weight pricing thresholds to optimize shipping cost.
What is the difference between ECT and burst strength ratings for corrugated boxes?
ECT (Edge Crush Test) measures a box’s resistance to crushing force applied to the edge—this rating (32 in this case) indicates pounds of pressure per linear inch the fluted edge can withstand before collapse. Burst strength, measured in pounds per square inch (PSI), determines how much pressure the flat wall surface can resist before rupturing. Both metrics matter: ECT predicts stacking integrity and pallet stability, while burst strength indicates puncture and impact resistance
