All About PVC

What are PVC Bottles?

When it comes to plastic bottles, there are a wide array of different materials. Each has its own unique properties and are suited to different industries, uses and products. As a proudly South African Plastics Bottle Manufacturer, B&I Polycontainers typically offers our clients a selection of five different types of material to choose from:

Today, we will be talking about PVC, very rigid yet resistant bottles available on the market.

What is PVC?

PVC, more formally known as Polyvinyl chloride, is the world’s third-most widely produced plastic, and one of the longest-serving. First synthesized in 1872 by German chemist Eugen Baumann, PVC has found a use for piping, window frames, medical products, wire and cable insulation, flooring, flexible packaging and more.

Of course, PVC is also used for making plastic bottles. Some of the properties of PVC plastic bottles are:

  • High Impact Strength
  • Brilliant Clarity
  • Excellent Processing Performance
  • Good resistance to Grease, Oil and Chemicals

 

PVC is also one of the least expensive plastics, making it widely used in many industries today. PVC Plastic Bottles are an excellent choice for salad dressings, mineral oil, and vinegar, and frequently used for shampoos and cosmetic products.

How are PVC bottles made?

PVC plastic bottles are most commonly used in blow-moulding. 

After the resin is melted and any additional colour pigments are added, the molten plastic is extruded through a metallic nozzle. After this, a mould clasps down on the plastic and high-pressured air is blown through the top of the mould. This creates a hollowed-out shape according to the specifications of the bottle. The bottle is then pushed out of the machine, and the operator cuts and trims the finished product to specification.

Due to the high resistance to chemical compounds and other liquids, PVC plastic bottles are well suited to be used in the pharmaceutical, automotive, chemical and cosmetic industries.

What are the Advantages of PVC?

  1. PVC bottles are readily available and extremely cost-effective.
  2. PVC bottles can be made with a wide array of colours and can have clarity only bested by PET.
  3. PVC bottles are very resistant to absorbing moisture.
  4. PVC bottles have a good chemical resistance over a wide range of bases and acids.
  5. PVC bottles have great impact strength.

What are the Disadvantages of PVC?

  1. PVC bottles are susceptible to UV degradation.
  2. PVC bottles have poor resistance to chlorinated solvents and aromatics.
  3. PVC bottles are highly flammable.
  4. PVC bottles are likely to become brittle from exposure to the cold.
