The typical property of paper manufacturing industry is Brightness and Opacity that make the paper more efficient in printing, wrapping, and commercial use but the process on how to acquire the properties without compromising the cost-effectiveness and the smoothness of the coating is a long-standing issue of the paper industry. Kaolin clay, and this has gone through the calcification process, has become a break through material to use in paper coating recipes, and it offers brightness that is indeed unsurpassed, high opacifying, and is highly compatible with coating binding material. As the market leader among all manufacturers of non metallic mineral products of the highest quality control standards and decades of experience in the industry, our calcined kaolin clay is time-tested to be of the highest strict quality that is required by the paper producers around the world and resulting in the same quality results at the lowest possible cost. Manufactured and shipped to China, and highly quality inspected, our kaolin clay products have now become a recognized brand, among professional buyers all over the world, with the objectives of the business of the high-quality mineral fillers and coating, high-quality and reliable.
Unmatched Brightness for Premium Paper Finishes
The mystery of the kaolin ware in the whiteness of the paper surface is the calcification process: by exposing the high grade of pure kaolin to the controlled temperatures we eliminate the organic impurities, iron oxides, and other discoloring compounds that reduce the natural brightness of untreated kaolin. The resultant product is an excellent refined calcined kaolin white clay of high whiteness index which imparts the coated paper a crisp clear brightness. This enhanced brightness is necessary in high quality printing as this will ensure that there will be brilliant color reproduction, clear texts and good quality visual finish to magazines, brochures, labels and packaging paper. The calcified kaolin clay will be used in all coating recipes, and will not change its color, when compared to raw kaolin or other fillers, and will not vary among batches- to-batch, which is a very important asset, supported by the strict quality control model of our company.
Superior Opacity to Eliminate Show-Through
Opacity is an obligatory feature of most paper products because it removes ink show through and allows the products to be read through the other side of the paper. The appearance of micro-voids within the clay particles formed during the calcification process, which then cause the particle structure of calcified kaolin clay, causes the scattering of the light, and thus, the opacification of the paper coating at the same time, without making the paper coating too congested and thick. The effect causes high opacities with lower coating weights resulting into the paper producers spending fewer costs on material purchases and increased printability and flexibility of the paper. The calcined kaolin clay is superior to a number of traditional fillers used in enhancing the transparency of the filler, it is the best filler in thin paper grade, light weight packaging and high volume printing paper where the cost of production and the performance of the filler is put into consideration.
Compatibility and Performance in Paper Coating Formulations
Besides brightness and opaque characteristics, kaolin clay following the calcification process has immense functional benefits that make it easier to make paper coating. Its very fine homogenous particle size, coupled with its high dispensability in water based applications, is one of the most easily dispersible formulations to be used in coating applications freely combining with latex binders, pigments and other additives to create a smooth consistent coating slurry. The dispersibility causes reduced clumping and improved coats application to provide smooth paper surface that enhances more adhesion to print on and wear reduction in printing equipment. In addition, we also supply the calcined kaolin clay that has good abrasion resistance and surface smoothness and once again, improves the working of the coated paper at the end-use. We have a large variety of non-metallic minerals including our calcined kaolin clay, which we offer in order to support our technical advice as well as our capabilities of customizing our products where paper manufacturers can add and remove ingredients in accordance with their specific production needs.
The final consideration to the solution of attaining impossible brightness and high quality of coating with consistent performance is the calcined kaolin clay to the paper producers who would like to step up their quality level to the next level. With the help of our international sales foundation, good logistic organization and our efforts of environmentally related factors, our calcined kaolin clay can give the consistency and good quality performance of the product that is needed by the paper production. Whether it is a high end printing paper, flexible packaging or commercial grade, coated paper our high-precision processed calcined kaolin clay is added to all the key attributes and it enables the manufacturers to innovate with paper products that stand out in the competitive market.
