NINGBO INNO PHARMCHEM CO.,LTD. provides essential chemical solutions for various industries, and our Polyvinyl Alcohol (PVA) is a key material for the paper manufacturing sector. PVA's unique properties, including excellent film-forming ability, adhesion, and water solubility, make it an invaluable component in producing high-quality paper products. This article highlights the diverse applications of PVA in the paper industry.

In paper manufacturing, PVA serves multiple critical functions. One of the primary uses is as a coating agent. When applied to the paper surface, PVA creates a smooth, uniform, and transparent film. This coating significantly enhances the paper's printability, ink holdout, and gloss. It helps to reduce ink penetration into the paper fibers, preventing feathering and ensuring crisp, sharp printed images. The improved surface smoothness also contributes to a better tactile feel and overall aesthetic appeal of the paper.

Furthermore, PVA acts as a binder in paper coatings and as a pigment binder. Its strong adhesive properties ensure that coating components are securely adhered to the paper substrate, preventing dusting and improving the durability of the surface. This is particularly important for coated papers used in printing, packaging, and specialty applications where surface integrity is paramount.

PVA also contributes to the internal strength of paper. When added during the papermaking process, it can improve the wet strength and dry strength of the paper sheets. This enhanced strength is crucial for various paper products, from packaging materials that need to withstand handling and moisture, to printing papers that must endure the stresses of printing and folding. The use of PVA can reduce the need for other, less environmentally friendly additives, aligning with industry trends towards more sustainable practices.

The versatility of PVA allows it to be used in different grades, tailored for specific paper applications. Whether it's for specialty printing paper, packaging board, or tissue paper, PVA offers a cost-effective and high-performance solution. NINGBO INNO PHARMCHEM CO.,LTD. is dedicated to supplying premium PVA that meets the rigorous demands of the paper industry, helping our clients produce superior paper products.
