The flute type determines the thickness of the corrugated cardboard. It has about 47 flutes per foot. Slightly thinner corrugated walls, but … Allow for the addition of new flute sizes in the future in an orderly way 4. D3950 Specification for Strapping, … Or The corrugated paperboard shall be tested for bending resistance by adapting TAPPI T- 3.5. 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). These machines, over time, have become very complex with the objective of avoiding some common problems in corrugated board production, such as warp and washboarding. The amount of virgin pulp fibers and the length of those fibers in a corrugated sheet substantially contribute to box strength. B flute was then developed for canned goods that were self-supporting, and so did not require boxes that supported much load. Linerboard is the flat paper that covers both sides of the sheet and the medium is the “fluted” or arched paper found between both liners. White papers can be coated to provide a superior substrate for greater print quality. Corrugated Flute Standards. These three layers of paper are assembled to each other with the help of a starch glue in a way which gives the overall structure a better strength. Its larger size generally provides greater strength and cushioning. For Protective Enclosures . In Europe, F-flute is being used for specialty packaging, point-of-purchase displays, jewelry and cosmetic packages, and shoe boxes. 4.1 This practice assists users in selecting appropriate performance characteristics of corrugated fiberboard or box construction, or both, commensurate with the user's need for packing and distribution of goods. 105 GSM WBF – Most Common Flute Standard; 112 SC and WBF; 150 SC and WBF; 175 SC and F; There are also a number of commonly used flute profiles or sizes, which are as follows: A FLUTE – 5mm; B FLUTE: 3mm; C FLUTE: 4mm; E FLUTE: 1.5mm; F FLUTE:.2mm; BC FLUTE: Double Wall – 6mm -Combination of B + C flutes With reduced fiber in the packaging, a more rigid box is created with less solid waste going into landfills. The type of fluting in corrugated boxes is denoted by the following alphabets: A, B, C, E, and F. Type C flute is the one used most frequently.  Flute B Thickness 2.4mm to 3.2mm (paper liner dependant). B flute was then developed for canned goods that were self-supporting, and so did not require boxes that supported much load. Points represent data. Corrugated flute standards: There are no single flue standards for the corrugated boxes. C-flute is sometimes chosen over B-flute for cases that will hold glass bottles, despite C-flute… Different flute weights are also available and depend on the strength of material required. Specifications for Singlewall E-Flute Corrugated Board . The profile of a corrugated web in Figure 3 is characterised by a letter, A, B, C, E or F, specified in Table 1 [1]. Therefore, a variety of grades reflecting varied performance levels are specified. C-flute is the most widely used flute size, commonly used for shipping cases.

This specification is provided as a public service by the Preservation Directorate of the Library of Congress. 3.2 TAPPI Standards may be ordered from TAPPI PRESS in CD-ROM or print-on-demand formats. Containing about 90 flutes per foot, E-flute has greater crush resistance and a relatively flat surface for high quality printing applications. Flutes also serve as an insulator, providing protection from sudden temperature changes. It is made on "flute lamination machines" or "corrugators" and is used for making cardboard boxes. According to the Chinese national standards “Corrugated board and standard test method” (GB6544~6548-86), the UV-shaped flute corrugated board should be 60° in the manufacture process. The corrugated industry produces the n1 transport packaging in the world the fefco gmp standard was launched at the end of 2003 renewed in 2006 to ensure that corrugated boxes meet all the requirements of quality safety and hygiene We are here to help you grow your business. Flutes are essentially the reinforcement that make up the board. Flutes per Linear Foot: 90 Thickness: 1/16".

At the same time, the vertical linerboard offers more strength and shelters the flutes from damage. In order to avoid liability for damage while shipping items in corrugated boxes, railroads in the US established a standard known as Rule 41. The paperweights that form the market of the corrugated boxes involves the use of following paper sizes for flute making. C-Flute: Appx 39 flutes per foot and measures 5/32" thick; common for shipping cartons. Therefore, the optimal flute angle could be 60° for corrugated board. B Flutes: With about 47 flutes per foot and 1/8” of thickness, this size flute is perfect for protecting canned goods. The flute size will determine the thickness of the wall of the box and its stacking strength. Because A-flute offers excellent stiffness qualities and short column crush resistance, it has application across a broad range of customer uses. Fax: 864-862-1005, Corrugated Flute Structure – A look at different flute profiles, What Do I Need? The flute, when anchored to the linerboards with a starched-based adhesive, resists bending and pressure from all directions. Corrugated board is manufactured on large high-precision machinery lines called corrugators, usually running at about 500 feet per minute (150 m/min) or more. The letter designation relates to the order that the flutes were invented, not the relative sizes. With the new standards for corrugated board performance and the proliferation of flute sizes it is now desirable to have a scheme for the classification of flute sizes that will: 1.
