Kraft/Corrugated Paper Machine
Kraft/Corrugated paper machine is the pulping and paper making machine used to make kraft paper/corrugated paper. Because the uses and manufacturing equipments of two types of papers are similar, they will be here introduced to you together.
Types and uses
Kraft paper is made from sulphate softwood pulp. The pulp is beaten and made on a long-mesh paper machine. Corrugated board is a paper board glued by liner paper and processed corrugated paper through corrugated rolls. It is generally divided into two types: single corrugated paper board and double corrugated paper board. Kraft paper is tough and inexpensive with good folding resistance and water resistance. Corrugated paper has the advantages of lightness and firmness, heavy load and pressure resistance, shock resistance and moisture resistance and low cost.
Kraft paper is mostly used for making shopping bags, envelopes, cement bags, etc. Corrugated paper also has many uses according to their respective paper layers:
- Single-faced corrugated board is generally used as a lining protective layer for commodity packaging or to make a lightweight card or pad to protect the goods from vibration or impact during storage.
- Three- layer or five-layer corrugated board is used to make the commodity packaging of the goods;
- Seven-layer or eleven-layer corrugated board is mainly used for making packaging boxes for mechanical and electrical goods such as furniture, motorcycles, and large household appliances.
Kraft/corrugated paper machine is designed for producing kraft paper or corrugated paper. It uses wood pulp board, waste paper, timber, bamboo, rice straw, bagasse, and other pulps to produce the paper at 50-300g/m2. The width of the paper ranges from 1092mm-3300mm. The design capacity is 10-150t/d. It comes in a variety of types, including the 1092type, 1575type, 1760type, 1880type, 2100type, 2400type, 2880type, 3200type，3600type，4200type and 4800type.
