We are a Chinese company founded in 1999 with more than 25 years of experience in packaging material, specialized in Anti-static, E-commerce & express, compostable bag,Thermal insulation packaging, heavy duty bags,kraft paper bag,today let me introduce the raw material kraft paper for your easy reference.
First part:What's Kraft Paper?
Kraft paper is paper produced using a specific type of pulping process, usually in paper making, the wood is first“Crushed”, the strength of paper can be improved by treating cellulose pulp with some chemicals (sulfate) . So he named his paper Kraft Paper. This is why this material is ultimately used as a packaging material because of its durability and usefulness in Kraft paper packaging. This is why it can solve thousands of problems, and there are many different names, such as wrapping paper, recycled paper, wrapping paper, Kraft paper, printing paper...
Second part:How is Kraft paper made?
1.The structural components of wood are lignin and cellulose. Since lignin can not be made into good paper, it must be separated from cellulose.
2.The chips are cooked in a liquid made from sodium sulfide and sodium hydroxide. They break down lignin and cellulose, leaving behind solid wood pulp.
3.At this point, the wood chips have been converted to pulp and screened to remove larger chips.
All kinds of paper products can be made by removing the impurities left in the pulp after washing.
Third part:Why is kraft paper better than normal paper?
1.Stronger Kraft Paper Kraft paper is stronger and more puncture resistant than regular paper because of its low lignin content and high sulfur content.
2.Kraft paper is durable and less costly to produce because it retains its natural color and texture, so no additional bleaching and dyeing steps are required. This can result in savings because of the need to reduce the handling of materials and to be away from the chemical environment. Excessive bleaching also reduces paper strength and increases production costs.
3.Use a variety of raw materials kraft paper can be made from a variety of wood, such as pine, bamboo and oak. That means it's easier to make, so there's plenty of supply -- which means the material costs are lower. The quality of wood is quite extensive, which means that high-density and low-density wood can be mixed together.
4. Recyclable and recyclable since almost all the chemicals used in the process can be recycled and reused, Kraft paper can be recycled, reducing the environmental burden and being environmentally friendly and economical. The main unrecycled by-products are turpentine and high oil, which are used for other manufacturing purposes.
