What is Pharmaceutical PVC Rigid Film?
 

· Development of PVC

 

PVC (Polyvinyl Chloride) is a synthetic plastic made from vinyl chloride monomers through polymerization reactions. It is the third largest synthetic polymer plastic in the world (after polyethylene and polypropylene) and can be traced back to the late 19th and early 20th centuries. PVC gradually became an important material in various fields. Among them, medicinal PVC hard sheets are a common pharmaceutical packaging material, with good sealing, moisture resistance, and corrosion resistance.

 

 

As early as 1835, the French chemist Henri Victor Regnault observed the polymerization phenomenon of vinyl chloride. However, it wasn't until about 50 years later that research on PVC truly began.

 

In 1862, British chemist Alexander Parkes first prepared a polymer product of vinyl chloride, but this was not PVC in the true sense. He copolymerized vinyl chloride and styrene in sunlight, but the product was not stable.

 

In 1872, German chemist August Wilhelm von Hofmann also attempted the synthesis of PVC but without success. It wasn't until 1912 that German chemist Fritz Klatte successfully synthesized PVC by polymerizing vinyl chloride monomers. Klatte conducted polymerization experiments using vinyl chloride and peroxide, successfully producing white solid PVC.

 

In 1926, American chemist Waldo Semon independently invented PVC and developed a commercially viable production method. He discovered a new plasticizer, making PVC a more flexible material. This discovery greatly promoted the commercial application of PVC and laid the foundation for modern industrial production of PVC.

 

Since the beginning of commercial production in the early 20th century, PVC has gradually become an important material widely used in various fields such as construction, automotive, medical, electronics, and packaging. Its advantages include corrosion resistance, wear resistance, and good weather resistance, making it widely used in various industries.

 

· Development of Pharmaceutical PVC Rigid Film

 

In the early to mid-20th century, PVC as a new type of plastic material was widely used in the industrial field due to its good physical and chemical properties. Due to its low cost of manufacture, high transparency, and ease of processing, PVC began to be used in the production of pharmaceutical packaging materials.

 

In the late 20th century to the early 21st century, pharmaceutical PVC rigid film was widely used in the pharmaceutical industry, covering various drug packaging forms such as tablets, capsules, granules, and powders. They played an important role in protecting drug quality, extending drug shelf life, and facilitating patient medication.

 

Today, with the continuous advancement of medical technology and the improvement of drug packaging standards, the manufacturing technology and techniques of pharmaceutical PVC rigid film is constantly being improved. At the same time, the emphasis on environmental protection and sustainable development has also promoted the development of pharmaceutical packaging materials towards more environmentally friendly directions, such as the research and application of biodegradable materials.
