Development of BOPP synthetic paper

International production of synthetic paper

At present, only a few manufacturers such as Prince of Japan, DuPont of the United States and South Asia of Taiwan can produce high-quality synthetic paper, and many manufacturers have applied for patented technology. The following are some representative patented technologies and production features:

① Japan Uniaxial Tensile Patent Law (46-40764,56-141339 and 56-118437). The core layer of biaxial polypropylene is used as the base material, and the surface layer is made of synthetic paper agent, which is produced by the composite processing of on-line laminating machine and uniaxial polypropylene (UOPP). The surface of the synthetic paper agent is inorganic powder, so there are many small holes on the paper and many shapes on the surface. In order to strengthen the gravure effect, the surface of the synthetic paper must be coated with a layer of water-based solution and then dried.

② In the United States, Taiwan three-layer bidirectional drawing method (US patent 5552011) This method uses polypropylene bidirectional drawing technology, synthetic paper products have a three-layer structure. The synthetic paper produced by this method has better mechanical strength than the products produced by the previous method, and the thickness uniformity of the synthetic paper is good, which is the most used production method in the world at present.

The development of domestic synthetic paper

China's packaging and printing industry has a large market demand for synthetic paper, mainly imported from overseas in the early stage, due to the excessive competition of conventional products, a small number of domestic BOPP enterprises began to develop and develop BOPP synthetic paper, in recent years, only Foplastic Group, Jiangsu Zhongda, Guangdong Huai Company, a small number of manufacturers to develop and produce synthetic paper, limited batch market. In terms of time cycle, Hubei Fust Group is at the forefront of the development of this new product, and has developed and developed BOPP synthetic paper with plastic material to prevent paperization and replace natural paper with functional properties, and its product performance is similar to that of similar international products.
