When it comes to packaging, one size — or thickness — definitely does not fit all. The durability and protection level of your Custom Shipping Boxes depend heavily on their thickness. At The Packaging World, we help businesses choose the right box strength to match their products’ weight, fragility, and shipping conditions.
Why Box Thickness Matters
The thickness of your box determines how well it can withstand external pressure, stacking, and rough handling during transit. Too thin, and your product risks damage; too thick, and you might be overspending on materials and shipping costs. Selecting the right balance ensures both product safety and cost efficiency.
Understanding Corrugated Box Structure
Custom Shipping Boxes are typically made from corrugated cardboard, which consists of three main layers:
-
Outer liner: The smooth, printable exterior surface.
-
Fluting (middle layer): The wavy paper layer that provides cushioning and strength.
-
Inner liner: The internal layer that adds durability and structure.
The combination of these layers determines the box’s overall thickness and strength.
Common Types of Box Thickness
-
Single-Wall Boxes
-
Best for: Lightweight and non-fragile products such as apparel, books, or small accessories.
-
Details: Made from one layer of fluting between two liners. It’s the most common and economical type of custom box for standard shipping.
-
-
Double-Wall Boxes
-
Best for: Moderate to heavy items like electronics, glassware, or bulk shipments.
-
Details: Two layers of fluting provide extra cushioning and compression resistance. These boxes are ideal when strength and protection are priorities.
-
-
Triple-Wall Boxes
-
Best for: Industrial, mechanical, or extremely heavy products.
-
Details: Contain three layers of fluting and offer maximum protection against impact and stacking pressure. They’re often used for exports or long-distance shipping.

Factors to Consider When Choosing Box Thickness
-
Product Weight and Fragility
Heavier or delicate items require thicker corrugated walls to prevent crushing and impact damage. -
Shipping Distance and Handling
Longer shipping routes or multiple handling points increase the risk of box compression — thicker boxes offer better durability. -
Storage and Stacking Requirements
If boxes will be stacked for extended periods, opt for double or triple-wall strength to maintain shape and protection. -
Budget and Sustainability Goals
Thicker boxes cost more but can reduce product damage rates. At The Packaging World, we help you find eco-friendly materials and cost-effective options that match your brand’s goals.
