Why Boulder Businesses Choose Us
Why Choose B-Flute Corrugated
Custom B-Flute Corrugated Packaging | Standard Shipping and Display Corrugated
B-flute corrugated is the most widely used corrugated flute profile globally for consumer product shipping -- with flute height of approximately 3.2mm and 47 flutes per foot, B-flute provides the balanced combination of compression resistance, puncture resistance, and printability that serves the broadest range of standard shipping and display applications. B-flute's moderate flute height creates adequate cushioning depth for most consumer products while providing a reasonably smooth exterior surface for flexographic printing at standard quality levels.
B-Flute Structural Performance
B-flute's structural performance parameters are calibrated to standard parcel carrier shipping requirements. Single-wall B-flute at 32 ECT is rated for products up to approximately 65 lbs in standard UPS, FedEx, and USPS parcel carrier conditions. The 47 flutes per foot provide adequate cushioning depth for most consumer products against vertical compression and lateral impact forces encountered in parcel carrier handling.
B-Flute Applications
B-flute is the default specification for RSC shipping boxes for e-commerce DTC fulfillment, manufacturer-to-retail shipping cases, mailer boxes for consumer products under 20 lbs, counter display units where adequate print quality on a standard surface is sufficient, and any standard product shipping application where 32 ECT performance is adequate.
B-Flute as the Global Shipping Standard
B-flute's global dominance reflects its optimization for the most common shipping parameters: products under 65 lbs shipped via parcel carriers with standard handling and stacking loads. The 32 ECT specification handles the stacking forces of standard warehouse and truck storage; the 3.2mm flute provides adequate cushioning for most consumer products against drop and impact forces in parcel handling. The resulting B-flute box serves 80% or more of consumer goods shipping applications without requiring additional cost of C-flute, A-flute, or double-wall alternatives.
B-Flute for E-Commerce Mailer Boxes
B-flute corrugated is the standard construction for consumer product mailer boxes -- the tuck-top boxes that DTC brands use for direct shipment to consumers. The B-flute construction provides adequate structural performance for most consumer products at standard parcel carrier drop and compression conditions. Full-color flexographic or digital printing on the white top-liner surface enables branded exterior communication. For DTC brands building branded shipping programs, B-flute mailer boxes with full-color exterior and interior printing are the standard investment.

B-Flute Corrugated Packaging in Boulder — FAQs
What is B-flute corrugated?
B-flute corrugated has a flute height of approximately 3.2mm and 47 flutes per foot -- the standard specification for most consumer product shipping and display applications. B-flute provides balanced compression resistance and printability that serves the broadest range of standard applications at the most economical specification.
What ECT rating should I specify for B-flute?
32 ECT B-flute is the standard for parcel carrier shipping under 65 lbs. 44 ECT provides additional compression resistance for heavier products (65-100 lbs). BC-flute double-wall construction is appropriate for products over 100 lbs.
Can B-flute be printed in full color?
Yes. B-flute can be printed using flexographic printing (up to 6 colors for high-volume programs) or digital corrugated printing (CMYK at 100-unit minimums without plate costs).
What is the difference between B-flute and C-flute?
C-flute (3.6mm) has a slightly taller flute than B-flute (3.2mm), providing marginally higher vertical compression resistance. B-flute is more commonly used for consumer product shipping and display; C-flute is more common in food service and larger-format shipping.
What is the minimum order for B-flute corrugated packaging?
Our minimum order is 100 units for custom B-flute corrugated packaging. Digital corrugated printing makes 100-unit branded B-flute packaging economical without flexographic plate costs.
