Polymer cork is a sealing device made of polymer materials such as polyethylene, polypropylene, or polyvinyl chloride, widely used in bottled beverages, pharmaceuticals, cosmetics, and other fields. Compared with traditional natural stoppers, polymer stoppers have better sealing, corrosion resistance, and consistency, which can effectively prevent the infiltration of oxygen and moisture and extend the shelf life of products.
The production process of polymer cork is flexible, and its physical and chemical properties can be adjusted according to different needs. In addition, they usually have good mechanical strength and temperature resistance, adapting to various environmental conditions.
In terms of environmental protection, many polymer cork materials can be recycled and reused, which meets the requirements of sustainable development. With the development of technology and advances in materials science, the application areas and properties of polymer stoppers are constantly expandi
