Why Boulder Businesses Choose Us
Why Choose C-Flute Corrugated
C-Flute Corrugated — Maximum Stacking Strength for Heavy Products and Industrial Shipping
C-flute corrugated (approximately 4mm thick) is the workhorse of industrial and retail distribution shipping — its 39-flute-per-foot construction provides superior stacking strength compared to B-flute, making it the preferred specification for products over 20 lbs, for palletized warehouse distribution, and for products requiring maximum cushioning against impact during shipping.
The thicker profile of C-flute creates larger flute cells that provide more air cushioning than B or E-flute. This cushioning advantage makes C-flute preferred for fragile products, glass items, and electronics that require impact protection beyond what B-flute provides. The tradeoff is larger box dimensions and higher DIM weight compared to B-flute.
C-Flute for Palletized Distribution
Products shipped on pallets in retail distribution experience vertical stacking forces that can crush inadequately specified corrugated. C-flute at 44 ECT provides the stacking strength to handle pallet-height stacking (typically 6-8 boxes high) without panel crush. We calculate required ECT based on your product weight, box dimensions, and maximum pallet stack configuration.
C-Flute for Fragile and Glass Products
The larger flute cells of C-flute provide more air cushioning volume than thinner flutes — an advantage for fragile products where cushioning is the primary protection mechanism. Wine bottles, glass jars, ceramics, and electronics with glass components benefit from C-flute's superior impact absorption. Combined with custom interior dividers or foam inserts, C-flute provides a complete protection system for high-value fragile products.

C-Flute Corrugated Packaging in Boulder — FAQs
When should I choose C-flute over B-flute?
Choose C-flute when your product weighs over 20 lbs, when the product is fragile and requires maximum cushioning, when distribution involves palletized stacking requiring high stacking strength, or when your box dimensions are large with long unsupported panels. For standard e-commerce under 20 lbs, B-flute is more cost-efficient.
What is the ECT rating for C-flute?
Standard C-flute is produced at 32 ECT and 44 ECT. 44 ECT is the standard for most C-flute applications requiring the stacking strength advantage of C-flute over B-flute.
Does C-flute print as well as B-flute?
C-flute prints comparably to B-flute for standard flexographic printing. The coarser flute spacing (39 vs 47 per foot) creates slightly more liner undulation, but the print quality difference for bold brand graphics is minimal.
Is double-wall corrugated the same as two layers of C-flute?
No. Double-wall corrugated combines two different flute types — typically B and C flutes — bonded between three liner sheets. This creates a structure with both flutes' advantages: B-flute's thinner profile and C-flute's stacking strength.
What is the minimum order for C-flute packaging?
C-flute corrugated boxes start at 50 units with digital printing.
