What Is The Difference between A Single-sided Kraft Card And Ordinary Kraft Paper?

Single-sided kraft paper is an important packaging material with broad application prospects. With the continuous progress of technology and the continuous expansion of the market, it is believed that the performance and quality of single-sided kraft paper will be further improved, bringing more possibilities to the carton packaging industry.
There are obvious differences between single-sided cardboard and kraft paper in many aspects.
Firstly, from the definition point of view, single-sided cardboard is a kind of cardboard with a special surface treatment, while kraft paper is a kind of tough, water-resistant, fold-resistant, rub-resistant and tear-resistant paper, mainly used for packaging items such as paper bags, envelopes, exercise books, etc.
Secondly, from the perspective of grammage and thickness, cardboard is usually heavier and thicker than ordinary kraft paper. Generally speaking, the heavier the weight, the greater the hardness of the paper. Therefore, the hardness of single-sided cardboard is often greater than that of kraft paper.
Furthermore, the uses of the two are also very different. Due to its relatively high hardness and aesthetics, single-sided cardboard is often used for high-end carton packaging, while kraft paper is mainly used for packaging items in daily life such as paper bags, envelopes, exercise books, etc. due to its tough and durable characteristics.
Finally, from the price point of view, although the price of cardboard calculated by sheet is usually cheaper than that of kraft paper, if it is calculated by bundle or ton, the situation may be the opposite. This is because the thick paper requires less raw materials during processing and the cost is relatively low.
