1 Brown Corrugated Boxes | 2 Corrugated Rolls What is the Difference Between Flute Sizes? There are four standard flute sizes: A, B, C and E. Flute sizing is determined by the height of the arch from top to bottom. The letters represent the sequence in which they were introduced, and do not refer to a size sequence (e.g. from biggest to smallest). For instance, "A" Fluting is the largest; "E" is the smallest, and "C" is sized in between "A" and "B". What's important here is not their sequence, but which size is the best size for your needs. | 3 Corrugated Sheets Pads What Are The Advantages Of Each Flute Size? In very general terms, the larger the flute the more stacking strength the board has; the smaller the flute the better printing surface the board has, and it folds more precisely. In terms of customer benefit, this means that should you experience some staking failure with a 200# "C" flute box, you could solve your problem by changing to "A" fluting rather than increasing your board weight. A change like that could also be a much more economical solution. On the other hand, if you are using rather small boxes that are die cut and need high quality graphics (such as point-of-purchase packaging), you may be better served by using "E" fluting. | 4 Withe Corrugated Boxes What's Best For You?
