Corrugated flute profiles are designated by letters that denote their size,
shape, and performance characteristics. Understanding flute types enables
proper specification for product protection, print quality, and cost efficiency.

**A-Flute:** The original corrugated flute with approximately 33 flutes per
foot. At roughly 5/32 inch (4mm) in height, A-flute provides excellent
cushioning and stacking strength. Best suited for fragile items and products
requiring substantial protection. The larger flutes create a bold visual
presence but present challenges for fine graphic printing.

**B-Flute:** With about 47 flutes per foot and 1/8 inch (3.2mm) height,
B-flute offers a flatter surface ideal for improved printability while
maintaining good crush resistance. Commonly used for retail-ready packaging,
POP displays, and canned goods. The tighter profile reduces board thickness
while preserving structural integrity.

**C-Flute:** The most widely used profile with approximately 39 flutes per
foot and 11/64 inch (4.3mm) height. C-flute balances cushioning, stacking
strength, and printability, making it the default choice for general shipping
boxes. It provides approximately 30% more stacking strength than B-flute.

**E-Flute:** A micro-flute with about 90 flutes per foot and 1/16 inch (1.6mm)
height. E-flute offers superior printability approaching folding carton quality
while providing light protection. Common for retail packaging, cosmetic boxes,
and consumer electronics. The thin profile reduces storage and shipping costs.

**F-Flute and N-Flute:** Even smaller micro-flutes (F at 128 flutes/foot,
N at 165+) enable premium printing and rigid, thin constructions. Used for
high-end cosmetic packaging, pharmaceutical cartons, and applications where
space efficiency rivals protection requirements.

**Combination Flutes:** Double wall constructions often pair different flutes
(BC, EB, AC) to combine properties — for example, EB double wall provides
excellent printability on the E-flute outer layer with robust B-flute cushioning.
