2019年5月7日 · Flutes give strength and structure to boxes, serving as a protector, insulator and cushioning device. Our system is set up to automatically select the flute options that will function best for your box size and style. E-flute is ideal for high quality printing with a thickness of 1/16″.

Flutes per Linear Foot: 47 Thickness: 1/8" E-Flute. Containing about 90 flutes per foot, E-flute has greater crush resistance and a relatively flat surface for high quality printing applications. The thin board profile of E-flute reduces outer box dimensions, and can help save storage space.

2024年5月7日 · What is E-Flute Corrugated Packaging? Within the most common flute sizes for corrugated packaging, e-flute is the smallest. Its thickness typically ranges from 1.5-1.8 mm—contrast that with A-flute, which generally comes in at 4.7-4.8 mm—and it has a fine, compact structure that results in a smoother surface compared to larger flute sizes.

E flute is the second-thinnest option, measuring approximately 1.6 millimeters–1/16 inch in thickness. The E flute is a good choice for reducing storage space and costs, commonly used for packaging consumer goods.

The box containing E flutes is thin and takes less storage space than other flute corrugated boxes. The most suitable usage of E-type flutes involves boxes for cosmetics, breakable delicate, and ceramic items.

E-Flute has a greater number of flutes per foot which gives it the greatest crush resistance and the flattest surface for high quality printing applications. The thin profile of E-Flute (one-quarter the thickness of A-Flute) reduces bulk and saves storage space.

2024年12月23日 · Types of Cardboard Flutes and Thicknesses. Flute types define a box’s strength and performance. Here’s a quick overview: E-flute (1.5 mm): Sleek, ideal for retail, pizza boxes, and small packages. B-flute (3 mm): Durable, used for custom mailers and shipping boxes.
