6. FREQUENTLY ASKED QUESTIONS (FAQ)

Q1: What is the weight capacity of this corrugated file holder? Will it bulge when filled with heavy documents?

A: It has high weight stability. The 3-ply E-flute corrugated structure provides vertical rigidity that holds full stacks of heavy A4 paper and catalogs without bulging.

Q2: Can the printed branding and index tables be fully customized with our logo?

A: Yes. We can print your custom logo, company branding, unique index layouts, and barcodes on all exterior panels using eco-friendly water-based inks.

Q3: Are these file boxes shipped assembled or flat-packed?

A: They are shipped flat-packed in high-density bundles to minimize freight volumes, assembling in seconds at your office stations.

Q4: Will the self-locking bottom collapse under heavy file weight without glue?

A: No. The interlocking bottom flap mechanism uses a weight-distributing layout that locks tighter as downward paper pressure increases.

Q5: How are bulk orders packed to prevent corner damage during international transport?

A: Bundles are wrapped in protective PE dust bags, bound securely, and packed into heavy-duty corrugated export cartons with corner protectors.
