Classification of High-Strength Corrugated Cardboard

 Classification of high-strength corrugated cardboard

1. Single face corrugated cardboard, with one side of the corrugated paper pasted with face paper. This type of cardboard is generally not directly used for making corrugated boxes, but rather rolled into simple shapes or cut into certain sizes to make cushioning and fixing materials.

2. single wall corrugated cardboard (three-layer corrugated cardboard), is made by pasting corrugatedd paper on both sides of face paper. flute can be used with any one of A, B, C, or E. Currently, double-sided corrugated cardboard is a widely used cardboard box in the world. Corrugated cardboard machinery

3. Double wall corrugated cardboard (five layer corrugated cardboard),  consists of two layers of corrugated paper and 3 layer of base paper. Structurally, it can be combined in various forms, so its performance also varies. Due to being thicker than ordinary single wall corrugated cardboard, it has stronger performance in all aspects, especially in terms of vertical compressive strength, which has been significantly improved. five layer corrugated cardboard are mostly used for packaging easily grabbed items, heavier items, and long-term storage items (such as fresh vegetables and fruits with high moisture content).

4. Triple wall corrugated cardboard (seven layer corrugated cardboard) is made of three layers of corrugated paper, that is, single face corrugated cardboard is pasted with one layer of double wall corrugated cardboard. various combinations of A, B, C, and E can be used.  So corrugated boxes made of this triple wall corrugated cardboard are mostly used for packaging heavy goods, replacing old wooden boxes, and are not limited to individual use. They are often combined with wooden pallets and pallets, and the joint between the two is fixed with steel straps or special box nails
