How to choose the right corrugated board?

Choosing the right corrugated board for your packaging needs is essential in ensuring the safety and functionality of your products. There are several factors to consider when selecting the appropriate corrugated board, and this article will discuss these factors in detail.

1. Strength and Durability: 

One of the primary considerations when choosing corrugated board is its strength and durability. You need to assess the weight and fragility of your products and select a board that can adequately protect them during storage and transportation. The strength of corrugated board is typically classified by its burst strength, edge crush test (ECT), or Mullen test rating. Burst strength measures the ability of the board to resist bursting under pressure, while ECT assesses its stacking strength. Mullen test rating measures the board's puncture resistance. Choose a board with appropriate ratings to match your product's requirements.

2. Flute Size:

Corrugated board comes in different flute sizes, which refers to the wave-shaped pattern of the cardboard. The most common flute sizes are A, B, C, E, and F, each with different characteristics. A and B flutes provide excellent cushioning and are suitable for fragile products, while C flute offers good stacking strength but less cushioning. E and F flutes are thinner and are often used for applications demanding a compact design and less weight. Consider the nature of your product and its transportation requirements to select the appropriate flute size.

3. Stacking Strength:

If you plan to stack your products during storage or transportation, it is crucial to consider the stacking strength of the corrugated board. The stacking strength indicates the load that a box can bear without collapsing or deforming. Higher stacking strength is required for heavier products or when stacking multiple boxes on top of each other. Ensure that the corrugated board you choose has the appropriate stacking strength to avoid any damage or accidents during handling.

4. Environmental Considerations:

In recent years, there has been a growing emphasis on sustainability and eco-friendly packaging solutions. Consider choosing corrugated board that is made from recycled materials or is easily recyclable. Look for certifications such as the Forest Stewardship Council (FSC) that ensure responsible sourcing of raw materials. Additionally, corrugated board that is lightweight and uses less material can help reduce shipping costs and minimize environmental impact.

5. Printing and Graphics:

If you require printing or custom graphics on your packaging, select a corrugated board that offers suitable surface properties for high-quality printing. Some boards may have a smoother surface, allowing for better ink adhesion and image clarity. The type of printing process and the desired visual result should be considered when choosing the right corrugated board for branding and marketing purposes.

6. Cost:

Finally, consider the cost of the corrugated board. While it's essential to ensure product safety and quality, you should also consider your budgetary constraints. Compare prices from different suppliers and evaluate the overall value, considering factors such as strength, durability, and sustainability. Avoid compromising on quality to save costs, as poor packaging can lead to product damage and customer dissatisfaction.

In conclusion, choosing the right corrugated board involves considering factors such as strength, durability, flute size, stacking strength, environmental impact, printing requirements, and cost. A careful evaluation of these factors will help you make an informed decision that meets your packaging needs and ensures the safety and functionality of your products.
