CORRUGATED BOX GUIDE

What you need to know about corrugated boxes

We have gathered the most common questions to answer before ordering corrugated boxes: how corrugated board is built, flute types, which box style fits which product, printing options, the production process and what determines the price.

What is a corrugated box?

Corrugated board is a layered packaging material made by gluing a wave-shaped middle paper (the flute) between two flat paper surfaces (liners). The air channels formed by the fluted layer make the material light, shock-absorbing and strong when stacked.

This structure makes corrugated boxes the most widely used packaging in shipping and logistics. They are much stronger than single-layer folding cartons and are used for everything from e-commerce orders to heavy industrial goods. They are recyclable and largely made from recycled fibers.

Flute types: E, B, C and BC double wall

The flute type sets the thickness and strength of the box. E flute (1.1–1.8 mm) offers high print quality thanks to its thin, smooth surface and is preferred for e-commerce boxes and retail packaging. B flute (2.4–3 mm) is a general-purpose option with high puncture resistance.

C flute (3.5–4.5 mm) stands out in stacking and impact resistance and is used for standard shipping cartons. BC double wall (6–7.5 mm) combines two flute layers and is the strongest option for heavy, bulky or long-distance loads.

Corrugated box styles and uses

For e-commerce shipping, the one piece mailer box and roll end styles close without tape and bring the unboxing experience to your brand. For books, calendars and flat products, the book wrap mailer protects the corners.

For bulk shipping and storage, the full slotted container (RSC) and slotted container are the most economical solutions, while auto bottom styles shorten packing time. We produce boxes with inserts and bottle carriers for bottles and glassware, and pizza boxes for restaurants.

Material and printing options

We produce our corrugated boxes with a natural kraft or white testliner surface. Natural kraft gives a simple, sustainable look; white testliner is ideal for vivid, full-color printing.

The printing method is chosen by quantity and design: offset for high volumes and color accuracy, digital for low volumes and personalization, UV printing for special effects. The outside, the inside or both sides can be printed, and extras such as water-based coating, varnish, foil stamping and window patching can be applied.

How are corrugated boxes made?

The process starts with a consultation where we review your product size, weight and shipping conditions. Then the box style, flute type and size are set, and the artwork is prepared for print. Before mass production, you can approve the size and print with a sample.

After approval, the corrugated sheets are printed, die-cut and glued where needed. Average production time is 15–20 business days after design approval.

What determines corrugated box prices?

The main price factors are box size, order quantity, box style, flute type, surface material, printing method and number of colors, plus any extras. As the quantity grows, tooling and setup costs are spread over more boxes, so the unit price goes down.

Our minimum order quantity is 500 units. To give you an accurate price, simply share your product dimensions, weight, estimated quantity and preferred style in your quote request.

Frequently Asked Questions

What you want to know about the ordering process

The key difference lies in the structure of the material. Folding cartons are made from thick stock paper and are generally used to package smaller, lighter retail products. Corrugated cardboard is more durable, with a 3-layer structure consisting of 1 corrugated paper layer between 2 flat liners. Thanks to its sturdy, durable structure, it is the most common choice for shipping.
