Flute C Thickness 3.4mm to 4.2mm (paper liner dependant ). B-flute was developed next and is much smaller. E-Flute: Appx 90 flutes per foot and measures 1/16" thick. This additional support provides a stiff, flat surface for high quality printing and die cutting. The standard flute profiles that we work with are E, B, BC and EB. Also listed in Table 1 are the take-up factors which quantify the length of the fluting per unit length of the board. The amount of virgin pulp fibers and the length of those fibers in a corrugated sheet substantially contribute to box strength. Most common flutes profiles … Three layers corrugated box or carton (Single Wall), the most common use type, is suitable for light-to-medium weight product or product that does not need high protection.

With reduced fiber in the packaging, a more rigid box is created with less solid waste going into landfills. Smaller flute profiles provide enhanced structural and graphics capabilities for primary (retail) packaging. It is best for applications where the corrugated container must bear some or all of the stacking load. Learn more about the European Federation of Corrugated Board Manufacturers, Europe’s leader in sustainable, biodegradable packaging. Corrugated fiberboard is a material consisting of a fluted corrugated sheet and one or two flat linerboards.

Flutes come in sizes, known as flute profiles, ranging from A-flute (the largest) to F-flute and below (microflutes). Often used for packaging glass products, dairy products, and furniture, C-flute offers good crushing resistance, good stacking strength, and highly acceptable printing properties. Because of its thin profile, cushioning properties, and flat surface, E-flute offers a strong alternative for conventional paperboard folding cartons including boxes for cosmetics, fragile glass, and ceramic items, and delicate instruments. The corrugated paperboard shall be tested for bending resistance in accordance with TAPPI T-836, and shall satisfy the following requirement: E-Flute: ≥ 1.6 N.m (MD) and ≥ 0.9 N.m (CD).
