Corrugated fiberboard, also known as micro-flute, consists of a fluted corrugated sheet and one or two flat linerboards. It is available in different wall thicknesses, known as flute sizes. All sizes have the option of a laminated printed top sheet.
- Recycled Fiber Made from 100% recycled material.
- Consistency Excellent: roll-to-roll consistency.
- Food Contact meets multiple national requirements for food contact packaging, e.g., US & Canada.
C-Flute – 3/16 inch thick
3500 – 3700 microns (3.5mm – 3.7mm) in thickness offers greater compression strength than ‘B’ flute, thus giving slightly better stacking strength for lighter products. C-flute is the most widely used flute size and is commonly used for shipping cases. Highly acceptable printing properties with a laminated printed top sheet.
B-Flute – 1/8 inch thick
2700 – 2900 microns (2.7mm – 2.9mm) in thickness and probably the most common type of fluting. Developed for packaging canned goods, B-flute is preferred for high-speed automatic packing lines, as well as many other forms of inner packing. B-flute is sed in all types of applications, including die-cut and flatter surface for higher quality printing with a laminated printed top sheet.
E-Flute – 1/16 inch thick
1100 – 1200 microns (1.1mm – 1.2mm) in thickness and gives excellent crush resistance and compression strength. It provides a high-quality surface to print upon and is most commonly used in smaller cartons and die-cuts applications. A robust alternative to paperboard folding cartons.
F-Flute – 1/32 inch thick
1100 – 1200 microns (0.8mm – 1.0mm) in thickness and was developed for small retail packaging. Its lower fiber content creates a more rigid box with less solid waste going into landfills. Often used for specialty packaging and fast food clamshell packaging.
