Corrugated boxes are the unsung heroes of packaging, used in nearly every industry for shipping, storage and product protection. But just how durable are corrugated boxes and what makes them such a reliable choice?
Made from layered cardboard with a fluted inner layer sandwiched between flat inner and outer liners, corrugated boxes offer an excellent balance of strength and lightweight flexibility. They are customisable, cost-effective and eco-friendly, making them a top choice for businesses and consumers alike.
In this blog, we’ll look at:
The durability of corrugated boxes comes from their unique construction. Here’s what gives them their strength:
Corrugated cardboard consists of three main layers for single wall, increasing to five layers for double wall.
The combination of these layers, combined with the choice of paper, distributes weight evenly, preventing crushing and bending.
In conjunction with choosing the flute type, the specific type of paper and the paper weight contribute to the strength and properties of the box. The main paper types are:
After determining the flute and paper make up, the constructional design of the box is the next determining factor contributing to the box's strength. Each design will have its unique strength, however, we can look at some FEFCO designs as a starting point. If stacking strength is needed, picking a 0427 design may be the most beneficial due to its unique folding, increasing strength at either end.
Corrugated boxes are tested for:
These tests ensure that durable corrugated boxes can withstand the knocks and bumps of shipping and handling.

From e-commerce to food packaging, corrugated boxes are used everywhere. Here are the most frequent applications for corrugated boxes:
Corrugated boxes are ideal for e-commerce and shipping because their durable, multi-layered structure protects products from damage during transit. Their lightweight nature also helps reduce shipping costs while maintaining strength.
They provide excellent insulation and ventilation, making them perfect for transporting perishable food items safely. They are also customisable with moisture-resistant coatings, ensuring hygiene and freshness.
Sturdy yet lightweight, corrugated boxes are easy to carry and stack during moves while keeping belongings secure. Their uniform sizes allow for efficient packing and optimised storage space.
Corrugated boxes offer a blank canvas for branding, allowing businesses to print logos and designs for a professional unboxing experience. They are also cost-effective and eco-friendly, appealing to both retailers and environmentally conscious consumers.
Corrugated boxes are essential in logistics packaging due to their ability to withstand stacking and long-distance transit, reducing damage rates significantly. Their lightweight nature also helps lower shipping costs while maintaining structural integrity under heavy loads.
Corrugated packaging provides excellent shock absorption, protecting sensitive electronics from drops and vibrations during shipping. Anti-static foam inserts can be used alongside corrugated boxes to make shipping electronics even safer.
Pharmaceutical-grade corrugated boxes ensure sterile and tamper-evident packaging for medicines and medical devices. Some designs even include thermal liners to maintain temperature-sensitive products like vaccines during transit.
Heavy-duty corrugated boxes with reinforced edges are ideal for shipping bulky automotive components like engine parts and brake systems. Custom die-cut inserts can also be added to secure irregularly shaped industrial tools and prevent movement during transport.

It depends on the material used and the box construction. We can use our experience to help guide you with your specific needs and weight requirements.
Standard boxes are not waterproof, but water-resistant coatings can be added to help with moisture protection.
They can be reused multiple times if left undamaged. Damaged boxes can easily be recycled in most waste streams.
