Analysis of China’s PVDC high barrier film application fields and market development prospects in 2023

High barrier film is a kind of packaging material with high barrier properties, preventing the penetration of oxygen, water vapor, microorganisms, insect pests, acid and alkali corrosive solvents, etc., and preventing the leakage of fragrance, organic vapor, etc., to maintain the internal environment of the packaging. It is stable and protects the contents, thus extending the shelf life and shelf life of food, medicine and other commodities. Polymer high-barrier materials are the most widely used and earliest-researched type of high-barrier materials. Among them, polyvinylidene chloride (PVDC) high-barrier films are widely used due to their excellent barrier properties and low price.

Polyvinylidene chloride (PVDC) is a copolymer with vinylidene chloride (VDC) monomer as the main component. It has a relative molecular mass of 20,000. It is non-toxic, odorless, safe and environmentally friendly. The high crystallinity and density of PVDC determine the high barrier properties of PVDC copolymer to water vapor and other gases, and PVDC has excellent properties such as freshness retention, fragrance retention, anti-corrosion, and heat resistance.

The “2023-2028 China PVDC High Barrier Film Industry Market In-depth Research and Development Prospects Forecast Report compiled and released by the Industrial Research Center recently It shows that in recent years, with the continuous improvement of the packaging industry’s requirements for packaging materials and the upgrading of consumer demand, the demand for high-barrier materials has continued to grow, and the domestic market demand for PVDC high-barrier film products has also grown. PVDC high barrier film is mainly used for packaging of food, medicine, chemicals, etc. In the pharmaceutical field, pharmaceutical packaging has strict requirements and needs to have good barrier properties such as water, light, oxygen, and odors. There are many pharmaceutical blister covers in Germany, Japan and other regions. Packed with PVDC/PVC materials; in the food field, PVDC high-barrier film can be heated by microwaves and has high transparency, high barrier properties and high-temperature cooking resistance, so it has great development potential in the field of food packaging; in addition, PVDC high-barrier film The film can also be used in the packaging of military supplies such as ammunition products. Due to its strong barrier properties, good weather resistance, and low cost, it is also widely used in the inner packaging of ammunition.

PVDC high barrier films include PVDC single film, PVDC coated film and PVDC multi-layer co-extruded composite film. Among them, PVDC multi-layer co-extruded composite film products have stronger stretchability than PVDC single film. PVDC single film is mainly used in military products, food and other fields; PVDC multi-layer co-extruded composite film can be used in food, medicine, military products and other fields, with a wider range of uses.

At present, the world’s major PVDC manufacturers include Dow of the United States, Solvay of Belgium, Kureha of Japan, etc.; Chinese PVDC manufacturers mainly include Zhejiang Juhua, Nantong Huiyufeng, etc. The high-barrier film industry has high technical and financial barriers. The development of PVDC high-barrier film products in China started later than abroad. PVDC high-barrier film products began to be used in the 1970s. However, with the development of domestic food, pharmaceutical and other industries, With continuous development, China’s PVDC high barrier film products are developing rapidly. In recent years, in addition to products such as PVDC high-barrier films, new high-barrier film products such as oxide-coated film materials have also continued to develop, and they have a certain substitution effect on PVDC high-barrier film products.
