Which is better, kraft paper or corrugated paper? What's the difference?

The difference between kraft paper and corrugated paper

Corrugated paper is a board like material made by bonding corrugated paper with corrugated paper that has been processed with corrugated bars to form a waveform. Compared to kraft paper for packaging, corrugated paper has many advantages. The cost of corrugated paper is relatively low, the quality of corrugated paper is relatively light, the processing of corrugated paper is relatively simple, and the required processing technology level is not very high. Another characteristic is that corrugated paper has high strength and is easy to store and transport.

Compared to corrugated paper, kraft paper is also widely used as packaging paper in printing and packaging factories, cardboard box factories, clothing factories, food packaging, and other industries. Kraft paper is also one of the indispensable materials for printing factories. Overall, kraft paper is more widely used than corrugated paper.

Kraft cardboard box board paper and corrugated paper base paper, one is "skin" and the other is "core". Cardboard, also known as kraft paper, is one of the main types of paper used in cardboard boxes. Cowhide paper must be tough, resistant to breakage, have high ring compression strength, and tear resistance. In addition, kraft paper should also have high water resistance. The main purpose of box board paper is to bond with corrugated paper cores and be used for packaging household appliances, daily necessities, needle cotton fabrics, cultural products, and outer packaging of traditional Chinese and Western medicine.

Corrugated paper is an important material for making corrugated cardboard. Corrugated paper base requires good fiber bonding strength, smooth paper surface, good tightness and stiffness, and a certain degree of elasticity to ensure that the cardboard box has seismic and compressive resistance. Corrugated base paper, also known as corrugated core paper, is the raw material paper that makes up the corrugated core of corrugated cardboard. It is worth noting that the moisture index of corrugated paper should be controlled. If the water is too small, the paper will be brittle and the corrugated paper will break during processing; Too much water and too soft paper can make it difficult to process and shape. The moisture content of general paper should be controlled at around 10%.

Which is better, kraft paper or corrugated paper

The question of which is better, corrugated paper or kraft paper, is mainly judged based on its purpose.

Cardboard is used for packaging and printing materials, and can be used for paper bags, cardboard boxes, and other packaging materials. It has a wide range of applications. If we have to compare kraft paper with corrugated paper, it is because kraft paper can be used to make corrugated surface paper.

Corrugated paper can be seen everywhere in daily life. For example, beer cartons are made of corrugated paper. Unlike kraft paper, corrugated paper is single sheet and can be divided into three layers, five layers, seven layers, etc. The use of corrugated paper is more extensive, and now the most commonly used is product packaging, which has gradually replaced wooden box packaging. It can be said to be both light and beautiful
