B-Flute Corrugated — Standard Mailer and Shipping Box Profile With Good Cushioning
B-flute (3mm) is the standard corrugated profile for mailer boxes and light shipping applications, providing good cushioning and puncture resistance.
Why Choose B-Flute Corrugated
About B-Flute Corrugated
B-flute corrugated (3mm thickness) is one of the two most common corrugated profiles used in packaging — the standard specification for mailer boxes, lightweight shipping cartons, and applications where cushioning performance is important alongside structural rigidity. B-flute provides significantly more cushioning than E-flute for fragile or delicate products, and its flat-crush resistance makes it appropriate for applications where stacking and compression loads are a concern. The slightly rougher surface compared to E-flute is less ideal for premium print quality but entirely adequate for standard quality CMYK printing.

B-Flute Corrugated FAQs
When should I choose B-flute over E-flute?
Choose B-flute when product protection and cushioning are more important than print quality and compact dimensions. For fragile products, glass, or items requiring more physical protection, B-flute outperforms E-flute.
What weight products are appropriate for B-flute?
B-flute handles products up to approximately 10-15kg effectively. For heavier products requiring more structural support, C-flute or double-wall construction is recommended.
Can B-flute boxes be printed?
Yes. B-flute with white liner accepts CMYK printing at standard commercial quality. The surface is less smooth than E-flute, so fine print details and screen-heavy printing are slightly less precise than on E-flute.
Is B-flute available in kraft and white liner?
Yes. B-flute is available with natural kraft liner for standard shipping applications and white liner for printed and premium packaging.
