Frequently Asked Questions
1. What is the difference between paperboard and corrugated mailing boxes?
The main difference lies in the material structure:
Paperboard boxes are made from thick paperboard, usually used for smaller and lighter retail products.
Corrugated boxes are more durable, made of three layers: an inner liner, an outer liner, and a fluted corrugated sheet in the middle.
Because of their strength and durability, corrugated boxes are the most popular choice for shipping.
👉 We can recommend the right material based on your product and shipping needs.
2. What is the minimum order quantity (MOQ) for mailing boxes?
Typically 300–500 pieces, depending on box style, size, and printing method.
3. Can I customize the size and design of my mailing boxes?
Yes, all mailing boxes can be fully customized in size, structure, printing, and finish.
We create solutions tailored to both your product protection and brand image.
4. Do you provide printing on both the inside and outside of the boxes?
Yes, we offer both single-sided and double-sided printing.
Single-sided printing is more cost-effective and commonly used for standard mailing boxes.
Double-sided printing creates a premium unboxing experience, but it usually comes at a slightly higher cost due to additional materials and printing processes.
5. Are mailing boxes strong enough for shipping?
Corrugated mailing boxes are designed for long-distance shipping.
They provide excellent protection against compression and impact.
6. Can I get samples before placing a bulk order?
Yes, samples are available to review size, material, and printing quality.
This ensures you are confident before starting mass production.
