1. Face/lining paper: the paper layer on the surface of corrugated board. Usually, the front layer is called face paper and the inside layer is called lining paper
2. Medium paper: also known as spacer or intermediate paper, the sandwich paper between corrugated core paper and corrugated core paper is generally made of imitation kraft card or corrugated base paper, and rarely used.
3. Corrugated core paper: The layers of corrugated cardboard that are pressed into a corrugated shape are called corrugated core paper.
4. Corrugated type: different corrugated types are divided according to the size and specification of corrugated. Common types are A, B, C, E, F.
5. Corrugated elongation coefficient: also known as corrugated rate, corrugated elongation coefficient, etc. It refers to the ratio of the length of corrugated core paper per unit length before and after crimping.
6. Sizing amount: the sizing weight of each sizing layer per square meter in corrugated board production. The unit is expressed in grams per square meter.
7. Fine corrugated: also known as micro corrugated, including E, F, G, N, 0 and other corrugated types. The corrugated board is thin and has good stiffness. It is generally used to make paper boxes for sales packaging.
8. Coarse corrugated paper: including A, B, C, K and other types of corrugated paper. The corrugated paper board is thick, with good cushioning property and high compressive strength, and is suitable for making transport packaging cartons.
9. Single side corrugated board: also known as pit board, it is made of a layer of corrugated paper pressed into corrugated shape and a layer of box board paper.
10. Single corrugated board: corrugated board made of two layers of cardboard and one layer of corrugated paper.
11. Double corrugated board: corrugated board made of two layers of box board paper, two layers of corrugated paper and one layer of medium paper.
12. Triple corrugated board: corrugated board made of two layers of cardboard, three layers of corrugated paper and two layers of medium paper.
13. Paper size: refers to the width of roll base paper.
14. Cutting length: the length of the cardboard cut by the tile line cross cutting machine is called cutting length.
