Talking about the difference between kraft paper and kraft paper

Kraft paper and kraft cardboard are both common paper materials in life. Listening to the name, it seems a little silly to tell the difference, like a family. Don't say it, you guessed it right! They are indeed brothers of the same mother. They have both common points and small differences. Let the editor interpret the kraft paper and kraft paper in detail for you! In fact, the concept of kraft paper and kraft paper is the same. The one below 120-150 grams is called kraft paper, and the one above 150 grams is called kraft paper. Generally speaking, the heavier the weight, the greater the hardness of the paper, so the hardness of kraft paper is higher than that of kraft paper. But its essence is the same. Kraft cardboard is generally brown, and there are many types, which can be divided into ordinary kraft cardboard, coated kraft cardboard, lined kraft cardboard, single-sided kraft cardboard, and double-sided kraft cardboard. Due to the hard material, it has good bursting resistance. Its thickness is very thick, the main grams are more than 200 grams, and the highest is more than 500 grams. It is generally used for industrial purposes such as carton and cardboard, and is commonly used in daily life such as computer packaging and mobile phone packaging boxes. Kraft paper is used as a packaging material, it is very strong and usually yellowish-brown. Semi-bleached or fully-bleached kraft pulp is hazel, cream or white. Quantitative 80~120g/m2; high tear strength, rupture work and dynamic strength. Mostly roll paper, but also flat paper. The kraft softwood pulp is used as raw material, and it is made by beating on a Fourdrinier paper machine. Mainly used for paper bags, envelopes, workbooks and other small household items. In terms of price, kraft paper is definitely more expensive than kraft paper if it is calculated by sheet, but the opposite is true if it is calculated by bundles (stacks) and tons. Because the thicker the paper, the less the surface needs to be treated and the lower the cost. news
