When customizing packaging, we inevitably encounter corrugated material. E-flute and B-flute are two major types. Choosing the right corrugated material directly impacts the packaging's load-bearing capacity, printability, and sustainability. Therefore, this article will quickly guide you through the differences between E-flute and B-flute.
E-flute is thinner, approximately 1.6mm thick, suitable for making common packaging boxes. Paired with white cardboard, it allows for high-quality printing, creating elegant boxes ideal for brands seeking minimalist design and a premium unboxing experience. Its thinness also reduces material usage, contributing to environmental friendliness.
B-flute is thicker, approximately 2.5mm thick, offering stronger cushioning and stacking strength. It's commonly used for outer cartons or inner linings of heavy products and for product shipping boxes. Its durability and thickness provide excellent product protection, making it widely used.
Both types can be manufactured using recycled fibers and are recyclable, supporting circular economy goals. However, if your priorities are brand visibility, retail aesthetics, or lightweight sustainability, E-flute is generally a better choice; while if you emphasize robust protection and cost-effective transport performance, B-flute remains a reliable option.

FAQ
What are the main thickness differences between E-flute and B-flute?
E-flute is thinner at about 1.6mm, offering a smooth surface for high-quality printing, while B-flute is thicker at roughly 2.5mm, providing stronger cushioning and stacking durability.
Which flute type is better for shipping heavy products?
B-flute is the better choice for heavy products due to its greater thickness and stacking strength, offering superior protection during transit compared to the thinner E-flute.
Is B-flute suitable for high-end retail packaging?
While B-flute is typically used for shipping, it can be paired with quality outer liners for retail. For premium unboxing experiences, E-flute’s print-ready surface is generally preferred.
