What is Corrugated Paper?<\/h3>\n

Corrugated paper is a type of paper that consists of two flat sheets with a wavy layer in between. It is commonly used for packaging due to its strength, durability, and ability to carry heavy loads. Additionally, the paper is lightweight and can be stacked in layers to save space. A special feature of corrugated paper is that it can be shaped into various forms, and it is very affordable, which makes it a popular choice for packaging goods and parcels.<\/p>\n

What is a 5-Ply Corrugated Box?<\/h3>\n

A 5-ply corrugated box is made up of three flat sheets of paper and two layers of corrugated paper. The corrugated paper layer on the outer surface of the box is usually B-flute, which is produced in varying sizes to provide flexibility and better impact resistance. It can support heavy loads. The inner layer is C-flute, which is ideal for cushioning and protecting items from impact. The standard flute combination is BC (B-flute on the outside, C-flute on the inside).<\/p>\n

What Grades of Corrugated Paper are Commonly Used?<\/h3>\n

Corrugated paper grades are available in a variety of options depending on aesthetic and functional needs. The different grades include:<\/p>\n
